Definitions

  • the present invention relates to fish tags, and more particularly to a new and improved fish tagging system which includes a new and improved anchor for securing the fish tag, a mechanism for connecting a streamer to the anchor, and an applicator for inserting the tag in the fish.
  • Tagging of fish is becoming an important con ⁇ servation effort for commercial and sports fisher- men alike, especially due to the worldwide en ⁇ vironmental awareness of the 1990's.
  • the data gathered through tagging programs is vital to estimating age, growth, migration patterns, dis ⁇ tributions, and stock structures of all species of fish, and most importantly to their ultimate sur ⁇ vival.
  • the most common tag is a stainless steel dart attached to a piece of mono- filament on which a yellow vinyl streamer is attached.
  • the streamer has printed on it an identification number and a return address to the person or organization sponsoring the tagging program.
  • This dart tag is manufactured by Floy Tag and Manufacturing, Inc. in Washington state and used extensively by the National Marine Fisheries Service in Miami, Florida.
  • the dart is a stainless steel anchor which fits onto a stain ⁇ less steel applicator protruding about two inches from a six foot wooden pole.
  • the streamer is attached to the stainless steel dart by mono- filament line which is inserted through a hole in the metal dart head and crimped through a flush mounted nut which is held by the dart.
  • the streamer is hand pressed into a notch in the wood pole.
  • the tag is inserted into the fish by applying force to the applicator. More specifically, the tag is inserted a full two inches into the flesh of the fish just below the forward part of the dorsal fin in the billfish and the second dorsal fin for tuna.
  • the tag is in- tended to be inserted completely through the petrygiophores, which is the bone structure which anchors the dorsal fin, so that it is locked in place behind the petrygiophores.
  • the dart is made from metal which is not bio ⁇ logically compatible with the fish.
  • the metal dart often causes infections and irritations that prevent the tag wound from healing properly, which ultimately results in tag loss.
  • the surface area of the tag is small (i.e., a thin blade) which provides less holding capability.
  • the thin dimen ⁇ sions and sharpness of the dart causes a slit type wound as opposed to a puncture type wound when inserted in the flesh. Slit type wounds heal slower than punctures. The slit is instrumental in tag loss since it doesn't heal as fast.
  • the thin stainless steel anchor is also bent slightly near the tip. This bend can hinder penetrating the skin of the fish if attempted at angles less than ninety degrees.
  • the applicator and its method of use can cause faulty application of the dart tag, which also can result in tag loss.
  • requiring that the dart tag be inserted behind the petrygiophores leaves much to chance. If the tag is not properly locked in place behind the petryg ⁇ iophores the tag could remain on the applicator as it is withdrawn from the fish. Alternatively, it could remain in the fish with nothing to hold on to except the flesh of the fish which may reject it.
  • the applicator has a stainless steel shaft which is rounded on the end with a slot forming two ears.
  • the dart tag must be bent to properly set in the applicator.
  • the dart head faces slightly sideways, and is inserted at an angle in the fish, i.e., off center.
  • An in ⁇ creased amount of force is needed by the user to insert the tag sideways.
  • the side force wears on the ears of the applicator which holds the dart, causing the ears to bend until they eventually break off.
  • Flesh can also be jammed between the ears of the applicator when inserted in the fish thereby preventing the dart head from coming off in the fish, and being withdrawn with the applicator.
  • the flesh, along with dirt that gets caught between the ears from frequent use of the applicator, can also cause the ears to rust and break off.
  • the notch in the wooden pole or tag stick, which the applicator is connected to swells, splinters and can fill with dirt, preventing the streamer from staying in the notch.
  • a rubber band is now used to hold the streamer to the pole.
  • a loop or bend is formed in the mono ⁇ filament connecting the streamer to the dart head.
  • the loop or bend in the monofilament causes a side force which can prevent the dart from coming off the applicator, since about one hundred pound test monofilament line is used.
  • the monofilament is usually crimped by a flush mounted nut on the dart head.
  • Monofilament is a polymer which crystallizes and becomes brittle when heat is applied to it.
  • heat is applied to the monofil ⁇ ament when it is crimped, tied in a knot, or heated to a bulbous end to connect the streamers to their respective anchor members.
  • Another tag used for tagging tuna has a nylon anchor member formed in the shape of a cone.
  • the tuna tag has two barbs which are created by mold ⁇ ing two slots in the cone and heating the sliced ends to bend them straight away from the base of the anchor, as opposed to being radiused or flared out.
  • the problem with the barbs is that they are not resilient enough to retract to their original positions after being inserted in the fish, which can result in poor holding capability and ultimately tag loss. Further, the barbs are not tapered to a sharp edge to shear the flesh of the fish to properly secure the tag in the fish.
  • the tuna tag has a cavity in the anchor for inserting an applicator.
  • the applicator has a metal shaft with a rounded head.
  • the streamer on the tuna tag is connected by monofilament to a hole in the top of the conical anchor member.
  • the enlarged part of the nylon anchor, that accommodates passage of the monofila ⁇ ment causes resistance when puncturing the fish, also causing tag loss.
  • the monofilament is bul ⁇ bous on the end connected to the anchor member to prevent the monofilament from falling back through the hole.
  • the bulbous end is created by heating the monofilament, which crystallizes over time and can break.
  • the other end of the monofil ⁇ ament is passed through the streamer and is sharply bent and covered with a plastic tube. The plastic tube is heat shrunk over the monofilament to prevent it from passing back through the streamer.
  • applicators are connected to a tag stick.
  • the tag stock may or may not have some type of stop system to prevent insertion of the tag too far into the fish, or entirely through the fish. Overinsertion is caused by the excitement of tagging large fish, such as bill- fish.
  • the tag stick is a pole made from fiberglass, wood or aluminum.
  • the applicator and tag stick when used with existing tags such as the dart tag and tuna tag, are only used as force applying mechanisms. They do not pass entirely through the anchor member to initially puncture the fish. Also, the applicators as discussed above for the dart type tags and the plastic tuna tag provide poor mechanisms for holding the anchor member on the applicator, which leads to faulty application.
  • a fish tag including an anchor member which includes a generally conical head, a rear portion extending from the base of the head, and two barbs flaring outwardly from the base of the conical head.
  • the barbs are at an angle to the axis of the conical head. The angle is larger at the end of the barb which is farthest from the head than at the end of the barb which meets the head.
  • the barbs are flexible for bending inward when inserted in the fish, but resilient enough to bend outward to their original positions once inside the fish.
  • the barbs are also rigid enough to not be bent outward substantially further than their original positions, in order to secure the anchor firmly inside the fish.
  • the anchor member also has an axial channel running through its conical head and rear portion through which an applicator may be inserted for holding the tag, and applying center force to the anchor member in order to puncture the fish to facilitate inser ⁇ tion of the anchor member.

  • the monofilament ends passed though the tube are folded back along the length of the exterior of the tube.
  • Surrounding the monofilament ends and the tube is a heat shrinkable material to prevent the monofilament ends from coming loose.

  • a gap 14a is formed between the streamer and the heat shrinkable tube which provides heterogeneous surface area for attachment of unwanted marine growth, such as barnacles and the like.
  • Such marine growth also attaches to the indicia of the fish carried by the streamer, such as the identification number and the address, and tends to destroy, deteriorate, erase, or severely degrade the quality of the indicia, over time or upon removal of the growth. Further, the growth tends to hide the streamer from view.

  • the small mass and surface area of the dart provide for very little holding capability if the dart breaks free from behind the petrygiophores. Very often the dart fails to be placed between the petrygiophores but remains only in the flesh. The applicator provides side force instead of center force. Also, flesh and dirt get caught between the ears, causing the dart to stick to the applicator and corrosion encourages the ears to eventually break off. The crimping of the monofilament heats it causing it to eventually become brittle and break.

Abstract

L'invention décrit un dispositif et un procédé de marquage intramusculaire destiné à un poisson; le dispositif de marquage comprend un élément d'ancrage (40) pourvu d'une tête en forme de cône tronqué, un canal axial (43) traversant la tête et deux barbillons (42) s'évasant vers l'extérieur à partir de la base de la tête. Les barbillons s'étendent d'abord parallèlement à l'axe de la tête et, ensuite, s'évasent vers l'extérieur pour former un angle de quarante-cinq degrés à l'extrémité du barbillon la plus éloignée de la tête. Chaque barbillon comporte une surface intérieure (46) et extérieure (45) qui convergent pour former un bord cônique aigu (47), créant ainsi une masse plus grande à l'extrémité du barbillon proche de la tête qu'à l'extrémité du barbillon la plus éloignée de la tête. Une telle disposition donne une certaine élasticité aux barbillons, de telle façon qu'ils s'incurvent en pénétrant à l'intérieur du poisson et retournent à leurs positions originales une fois qu'ils se trouvent à l'intérieur du muscle du poisson. Un dispositif d'application (60) pourvu d'un applicateur à tige cônique aigue (612) passe à travers le canal axial pour former un cône axial pour former un cône complet avec la tête de l'élément d'ancrage pour percer le poisson.
