Description

REMOVEABLE AQUATIC BASKET AND FLOAT SYSTEM AND METHOD

Field of Invention

The present disclosure relates to an aquatic basket system and method of using the same. In particular, the use of the aquatic basket system facilitates handling of the aquatic basket system during inspection, treatment, and/or harvest of an aquatic organism contained in the aquatic basket system.

Background of Invention

Conventional aquatic basket systems for cultivating aquatic organisms, e.g., bivalve molluscs, are typically not easy to handle, and present challenges when attempting to attach a conventional aquatic basket system to a support system, e.g., a longline or drip tube. Likewise, conventional aquatic basket systems also typically present challenges when attempting to disengage the aquatic basket system from the support system when, for example, transferring the basket system to a boat or to a land base for inspection, treatment, and/or harvest. Accordingly, there exists a need for an aquatic basket system and associated method of use that facilitates ease of handling of the aquatic basket system during inspection, treatment, and/or harvest of aquatic organisms contained in the basket system.

Summary

For present purposes, aquatic organisms should be understood to include organisms of the class: Bivalvia, more particularly organisms of the sub-classes: Fleterodonta, Paleoheterodonta, Protobranchia, and Pteriomorphia. In particular, of present interest are members of the above sub-classes that are at least suitable for consumption by a human. Such members suitable for consumption by a human of the above sub-classes should be understood to include, but not be limited to, clams, cockles, mussels, oysters, and scallops. It will be appreciated that aquatic organisms may also include algae, aquatic plants, crustaceans, fish, molluscs in general, and/or other organisms amenable to aquafarming.

For present purposes, aquatic culture should be understood to include the cultivation of aquatic organisms in fresh water, brackish water, estuarine water, and saltwater environments.

Preferably, first portion 110 is part of flip adapter 114 having an upper member and a lower member 164 (Fig. 2), the upper member being detachable from lower member 164, the upper member and lower member 164, when engaged with each other, being configured to sandwich longline 108 therebetween.

As shown in Fig. 5, second portion 112 of attachment mechanism 160 forms a locking bar 116 that is slidable into a portion of aquatic basket 104. Locking bar 116 is configured with predetermined lock positions 118 permitting locking bar 116 to selectively lock aquatic basket 104 to the aquatic basket float 102 and longline 108 at a desired lateral orientation relative to longline 108. Aquatic basket attachment mechanism 160 is preferably configured to position a single longline 108 between aquatic basket float 102 and aquatic basket 104. Aquatic basket attachment mechanism 160 preferably includes a bearing attachment attachable to the longline. The bearing attachment includes two opposed bulbous end portions connected by a tubular middle portion configured to accommodate the longline therethrough as shown in Fig. 2. The present disclosure also relates to a method of attaching aquatic basket 104 to longline 108. The method includes inserting locking bar 116 into a portion of aquatic basket 104, and attaching aquatic basket 104 and locking bar 116 to aquatic basket float 102 at an orientation where long axis 166 of aquatic basket 104 is perpendicular to longline 108. Preferably, longline 108 is interposed between aquatic basket float 102 and aquatic basket 104. The method also includes detaching aquatic basket 104 from aquatic basket float 102 and longline 108. The method further includes flipping aquatic basket 104 about a longitudinal axis 168 of longline 108 while aquatic basket 104 is engaged to longline 108.

Figs. 6 to 17 show another preferred embodiment of an aquatic basket attachment mechanism, labelled as 206. Aquatic basket attachment mechanism 206 includes a float spine 208 and at least one locking mechanism 210, 212 (Fig. 11).

Aquatic basket float 102 is made of a buoyant material configured to securably receive one or more fasteners, for example, one or more foam lock pins 270, 272 without destroying aquatic basket float 102. Each fastener 270, 272 has a grip 274 and a stem 276 (see Fig. 15). Preferably, each fastener 270, 272 is configured to pass, in use, through aquatic basket float 102 and engage with float spine 208 to lock aquatic basket float 102 to float spine 208.

Locking mechanism 210, 212 includes one or more anchor(s) 284, 286 (Fig. 11) such that, in use, float spine 208 is locked onto one or more anchor point(s) on aquatic basket 104. Float spine 208 also includes one or more keyways 278, 280 each shaped and configured to receive, in use, the locking tab of one or more fasteners 270, 272. Each keyway 278, 280 includes a locking configuration 282 (Fig. 16) located therein such that, in use, each fastener 270, 272 can be positioned in a locked position to lock aquatic basket float 102 and aquatic basket 104 onto longline 108. As shown in Fig. 6, aquatic basket attachment mechanism 206 includes a bearing attachment 120 attachable to a longline 108. Preferably, bearing attachment 120 includes two opposed bulbous end portions 122, 124 connected by a tubular middle portion 126 configured to accommodate longline 108 therethrough.

In a preferred embodiment, at least one of the one or more anchors 284, 286 is a slidable lock bolt shaped and configured to be lockably received, in use, by a lock anchor point located on the aquatic basket 104. Slidable lock bolt 284 may, as shown in Figs. 11 to 13, be pulled in a first direction 300 to locate, in use, slidable lock bolt 284 in a locked position relative to the lock anchor point and pushed in a second direction 302 to locate, in use, slidable lock bolt 284 in an unlocked position relative to the lock anchor point.

Preferably, the one or more anchor points may be a loop located on aquatic basket 104. An anchor point may be formed integral to the aquatic basket or may be fitted to the aquatic basket.

Preferably, in use aquatic basket float 102 biases each the flange of each stem 276 into locking engagement with a respective locking configuration 282. It will be appreciated that elastic deformation of the aquatic basket float 102 as each fastener passes through aquatic basket float 102 to lock aquatic basket float 102 to aquatic basket 104 may provide such bias.

Fig. 14 shows a preferred embodiment of fasteners 270, 272 in a first position (Fig. 11 ) and a second position (Fig. 12). It will be appreciated, the first position may represent a locked position and the second position an unlocked position, or vice versa. Reference to the locked position shall, for present purposes, be understood to mean where aquatic basket float 102 is locked onto aquatic basket 104, and unlocked position shall be understood to mean where aquatic basket float 102 may be disengaged from aquatic basket 104.

Figs. 15 to 17 show a preferred embodiment of a fastener (for example, 270) and float spine 208. Float spine 208 includes one or more keyways 278, 280 each shaped and configured to receive, in use, the flange of stem 276 of the fastener (for example, 270). Each keyway 278, 280 includes a locking configuration 282 located therein such that, in use, each fastener 270, 272 can be positioned in a locked position to lock an aquatic basket float and an aquatic basket onto a longline.

Preferably, the aquatic basket system is manufactured from a degradation- resistant material. Also preferably, the aquatic basket system is manufactured from a material that is corrosion resistant. Such degradation resistant and/or corrosion resistant material may be a UV resistant polymer, a polymer including an anti-UV stabilizer, a polymer resistant to thermal degradation, a polymer resistant to photo-oxidation, a polymer resistant to ozonolysis, a polymer resistant to oxidation, a polymer resistant to chain scission, and/or any combination of the afore-mentioned polymers. The polymer of present interest may include one or more antioxidant(s), a light stabilizer such as a UV absorber, a UV quencher, or a hindered light amine stabilizer. The polymer may also include an acid scavenger, a heat stabilizer, and a biocide.

Such a biocide may limit degradation of the polymer by a deleterious organism or pathogen, colonisation of the aquatic basket by such a deleterious organism or pathogen, and/or limit/reduce disease in a bivalve contained in the aquatic basket or human having consumed the bivalve. Such a deleterious organism or pathogen may be a bacterium, a fungus, a protist, a virus, a plant, a sponge, a snail, a whelk, a crab, a lobster, a flatworm, a leech, a sea star, a fish, and/or any other animal known to deleterious to bivalves.

Such degradation resistant and/or corrosion resistant material may be a suitable metal or metal alloy that is resistant to corrosion. A particularly preferred metal or metal alloy would be resistant to corrosion in an aquatic environment. A person skilled in the art will appreciate that such metal or metal allow may include, for example only, stainless steel and/or duplex steel, at least of marine grade.

Preferably, the aquatic basket float as herein disclosed may be manufactured as a single buoyant component or be assembled from multiple buoyant components, i.e., two or more buoyant components. Also preferably, the aquatic basket float as herein disclosed may be made of a buoyant material configured to securably receive one or more fasteners, for example, one or more screws, one or more clamps, one or more clips, and the like without destroying the aquatic basket float. The term “destroyed” as used herein should be interpreted to mean reduction of the buoyancy of the float such that the aquatic basket is insufficiently and/or ineffectively supported in an aquatic environment as a result.

It will be appreciated that the buoyant material should be buoyant in an aquatic environment. Such buoyant material may include a foam. Such foam may be an open-cell foam, a closed-cell foam, or a combination of an open-cell and a closed-cell foam. Preferably, the foam may be manufactured from polyurethane, polystyrene, a resin, and/or any suitable manufactured foam material. The foam will have a high strength-to-weight ratio. The foam may be an integral skin foam having a high-density skin and a low-density core. The foam may include hollow particles within a matrix material. The hollow particles may be manufactured from a suitable material such as glass, a ceramic, and/or a polymer. Alternatively, the foam may be a suitable metal foam. Preferably, the metal foam should be corrosion resistant and/or enclosed in a corrosion resistant skin.

In use, the basket may be detached from the longline during inspection, treatment, and/or harvest of an aquatic organism contained in the aquatic basket system. Such inspection, treatment and/or harvest of the aquatic organism contained in the aquatic basket system may occur in situ, i.e., on or alongside a boat, or ex situ, i.e., on land, a pier, a jetty, or the like. Also, in use, aquatic basket 104 may be flipped 90°, 180°, 270°, 360°, or to an extent required about longitudinal axis 168 of longline 108 for inspection, treatment, and/or harvesting of an organism contained in aquatic basket 104.

Inspection may include checking growth progress, checking biofouling, checking for presence of a pathogen, e.g., a bacterial, a fungal, a parasite, a protist, a viral, and/or an algal pathogen, or a plant or animal deleterious to the organism contained in aquatic basket 104. Treatment may include treatment to remediate any effect arising from the presence of a pathogen, a plant, and or animal deleterious to the organism contained in aquatic basket 104.

Referring now to Figs. 18 to 36, an aquatic basket system 300 is shown in accordance with another preferred embodiment of the present disclosure.

System 300 is similar to system 100 except that system 300 is configured with a tube bracket assembly 380 configured to secure a float 302 and a basket 304 to a drip tube or longline 308. System 300 is configured to permit the basket and/or float to be interdependently attachable and detachable to the longline, for fast and efficient assembly and disassembly. Referring to Fig. 18, bracket 380 includes a first, handle engagement end 381 , and a second float engagement end 382 opposite the handle engagement end along a longitudinal axis. Bracket 380 further includes a line retention or engagement area 383 located approximately halfway along the length of bracket 380. Line retention area 383 has an axis oriented generally perpendicular to the longitudinal axis of bracket 380 so that basket 304 is oriented generally perpendicular to the longline when attached to the longline.

Referring to Figs. 18 to 20, longline 308 is secured to bracket 380 with a pair of clips 384. Each clip 384 is configured to overlie and snap into cooperative engagement with a clip engagement area 385 located at ends of line engagement area 383. As shown in Figs. 19 and 20, clip 384 includes an end that is configured to tuck under tabs located at each end of line engagement area 383.

Figs. 22A to 24 show more detail of handle engagement end 381 , and its interaction with a basket latch bracket 386 and release handle 387. Referring to Figs. 22A and 22B, handle 387 includes a pair of parallel handle pins 388 projecting from a handle portion. Flandle pins 388 each preferably include a tab stop 389 configured to retain handle 387 to main bracket 380, and limit longitudinal movement of handle 387 when engaging and disengaging basket 304 to main bracket 380. Referring to Fig. 24, handle pins 388 are preferably configured to reside and be retained under a portion of basket latch bracket 386.

Fig. 25 shows basket 304 with basket latch bracket 386 and a basket axle bracket 390 engageable with the top of basket 304 using a slidable locking bar, such as previously described above. Basket latch bracket 386 and basket axle bracket 390 are secured to basket 304 by sliding a locking bar through the top of basket 304, and through the lower surfaces of brackets 386 and 390 similar to the interaction between the locking bar and the basket described above in relation to the embodiment of Figs. 1 to 17.

Referring now to Figs. 26 to 30, main bracket 380 is positioned and angled over the top of basket 304 such that a pair of tabs of float engagement end 382 fit under corresponding pins 391 of basket axle bracket 390, as shown in Fig. 27. Once float engagement end 382 is engaged with axle bracket 390, handle engagement end 381 of main bracket 380 is rotated towards basket 304 so that handle engagement end 381 engages with basket latch bracket 386 by pushing handle engagement end 381 into place as shown in Figs. 28 and 29. This includes pushing the handle until a latch 392 at handle engagement end 381 engages with a latch receiving region of handle 387 to latch the handle in place, as shown in Fig. 30. Referring now to Fig. 31 , float 302 has an opening end 393 that preferably includes a pair of opposed key slots 394 configured to receive a float pin key 395 therethrough, as shown in Fig. 34. Referring to Figs. 32 to 34, float 302 is engaged with main bracket 380 by inserting the float loops under opposed pins 396, 397 at float engagement end 382. This engagement permits float 302 to be attached to main bracket 380 by rotating opening end 393 of float 302 towards handle engagement end 381 of bracket 380, until key slots 394 are aligned with the curved portion 398 (Figs. 30 and 34) of handle engagement end 381 of main bracket 380. Once curved portion 398 is aligned with key slots 394, float pin key 395 is laterally inserted therethrough in Fig. 34 to secure float 302 to main bracket 380 as shown in Fig. 35.

To disengage the basket from main bracket 380, a user lifts up latch 392, and pulls out release handle 387 longitudinally away, as shown in Fig. 36. Float 302 may be disengaged from main bracket 380 by pulling pin key 395 out.

It may be seen from above that the basket and float may be independently engaged and disengaged to the main bracket, and hence, to the longline. Such an arrangement provides enhanced flexibility for maintaining either or both the float and basket, and increases the ease of deploying an aquatic harvesting system in a marine environment. This is particularly advantageous in adapting the system in challenging marine environments, and permits the easy replacement of a defective or broken element without a laborious and time- consuming shutdown and replacement of the entire line to replace what essentially might only be a single problematic element.

If desired, the system may be configured so that the attachment of the basket to the longline permits the basket to remain in a fixed orientation, such as an inverted orientation, so that any aquatic fowling may be dried out to help maintain sanitary conditions.

It will be appreciated that the basket may be in any dimensional configuration suitable for the intended purpose. For example only, the basket may have a square or oval configuration. In situations where the basket has a square orientation, or where its longest dimension is parallel to the longline when attached, it will be appreciated that basket rotation about the longline would be parallel to that longest dimension. If desired, the baskets may be configured in an interconnectable modular manner so that they are attached to one another to form one or more elongated baskets of suitable dimensions depending upon the environment being engineered towards.

Exemplary advantages of one or more preferred embodiments of the disclosed aquatic basket system and method of use of same include:

• Facilitating ready attachment or removal of the float to/from the aquatic basket while in use, i.e., in position on the longline.

• Attachment of the float around a bearing using a flip adapter, which can be removed once the aquatic basket is removed.

• Lock bars configured to engage the flip adapter in a plurality of suitable positions balanced around the bearing.

• Lock bars easily removable with endcaps of the basket in place.

• Lock bars adapted to increase the lock adapter positions.

• Ready access to the lock bar such that the aquatic basket can easily be disengaged from the float.

• The float fitted snugly to the top of the aquatic basket.

• Float can be easily fastened to the bearing.

• Float remains attached to the line when the aquatic basket is disengaged and readily/easily re-attached to the aquatic basket when required.

• The flip adapter shaped and configured to fit snugly around appropriate configurations of the aquatic basket.

• The flip adapter including a lock tab design that corresponds to the lock adapter on the flip adapter ends, with a preferred at least one additional engagement of the lock bar under the bearing.

• Bearing on the line stops the basket from migrating along the line.

• Bearing reduces wear giving resistance and strength and protecting the line to hold the basket in place.

• If the line breaks, all baskets remain on the line, rather than threading off the line. • Baskets can be individually collected to be utilised on existing onshore grading systems. This gives greater flexibility to the farmer as they have options to either work on their boat or punt if they have purchased the necessary infrastructure or use current land base.

• Baskets can be deployed individually rather than requiring threading all baskets onto a single line.

• With the floats removed, baskets can be sunk underneath ice for wintering.

• Baskets can be sunk during aggressive environmental conditions underneath wave action to reduce the risk of damage to infrastructure and to the bivalves, for example oysters.

• The line is central between float and basket, i.e., as close to the centre of gravity to help facilitate ease of flip of the basket and float.

It will be appreciated that one or more of the aforementioned advantages need not apply to every embodiment, but is dependent upon factors such as dimensions, environments, and operational use and purpose. The features described with respect to one embodiment may be applied to other embodiments or combined with or interchanged with the features of other embodiments, as appropriate, without departing from the scope of the present disclosure.

Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the features disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
