  • Suitable zooplankter species include, but are not limited to, brine shrimp, rotifers, Artemia spp., Artemia salina,
  • the purpose of the present invention is to provide an inexpensive and highly nutritious source of food derived by bacterial, algal, and/or yeast fermentation for mass production of rotifers, shrimp, larvae, and other filter feeders, such as oysters, clams, mollusks, and mussels.
  • rotifers, shrimp, larvae, and other filter feeders such as oysters, clams, mollusks, and mussels.
  • a major impediment to marine fish aquaculture is the high energy and labor cost (up to 85% of total operation costs according to Bolton and Fulks (Bolton 1982; Fulks and Main 1992)), and practical difficulties associated with growing high-quality algae. Frequently, it is difficult for a hatchery to supply sufficient algae at all times of the year.
  • Unicellular algae are generally photoautotrophic and, as such, require light for photosynthesis during which carbon dioxide is reduced to organic carbon and oxygen is released. Hatcheries are generally using electric lighting for indoor algal cultures or, if climate conditions permit, algae can be grown in outdoor tanks. However, cell densities and growth rates are limited by light penetration into the culture medium. Photoautotrophic culture methods are energetically inefficient, costly, and require hatcheries to employ a skilled person to maintain the algal culture system. [017] It is an objective of the invention to provide rotifers, shrimp, larvae, and filter feeders with inexpensive and high quality dry feeds that are produced from phototrophically or heterotrophically grown bacteria, algae, and yeast.
  • This yeast may be partially digested baker's yeast with cellulase or brewers yeast having a thin and easily digested cell wall.

  • Crypthecodinium cohnii, and Schizochytrium sp. have exceptionally high levels of docosahexaenoic acid (DHA, 22:6n-3), which is an essential fatty acid supplement in a marine fish larval diet (reviewed by Kanazawa (Kanazawa 1993) and Watanabe (Watanabe 1993)).
  • DHA docosahexaenoic acid
  • Vitamin B ⁇ 2 supplemented waste stream co-products of algae up to 400 ⁇ g/100 g dry matter. More specifically, these feeds can be supplemented with additional algae-derived products containing phosphohpids rich in essential fatty acids such as docosahexaenoic (DHA, 22:6n-3) and arachidonic (ARA, 20:4n-6) acids.
  • DHA docosahexaenoic
  • ARA arachidonic
  • These extracts can contain additional essential growth factors, antibacterial agents, bacterio static compounds, pigments, and essential amino acids.
  • macroalgae include, but are not limited to, Laminaria sp., Padina sp., and Gracillaria sp.
  • zooplankton refers to members of three major groups of invertebrate animals: the rotifers, copepods, and cladocerans. All three of these major groups have species adapted to pelagic (open water), littoral (vegetated), and benthic (bottom) environments, and are widespread in both freshwater and marine environments.
  • Rotifer shall mean any of a class of minute, usually microscopic, but many-celled aquatic invertebrate animals having the anterior end modified into a retractile disk bearing circles of strong cilia that often give the appearance of rapidly revolving wheels. Rotifers are used as a source of live feed for aquatic animals during their early larval stage.
  • Artemia belonging to the phylum Arthropoda in the class Crustacea. These tiny crustaceans can be found in salt lakes and brine ponds throughout the world. Artemia brine shrimp are used as a source of live feed for aquatic larvae during their early and late larval stages.

  • algal feed shall mean any dry feed form, which includes any portion of algal component.
  • enrichment feed shall mean any type of feed either dry or moist, that is used for short duration feeding of aquatic zooplankton, prior to their harvest, in order to deliver essential nutrients for aquatic larvae when fed to these zooplankton.
  • filter feeder is any species of invertebrate animal that obtains its food from aquatic media by removal of small particles or organisms by any mechanism.
  • macroalgae refers to algae that in at least one life stage form large structures that are easily discernable with the naked eye. Usually these organisms have secondary vascularization and organs. Examples of different groups containing macroalgae follow but are not limited to the chlorophyta, rhodophyta, and phaeophyta.
  • microalgae refers to prokaryotic and eukaryotic algae that are classed in many different species. Normally the prokaryotic algae are referred to as cyanobacteria or bluegreen algae.
  • the eukaryotic microalgae come from many different genera, some of which overlap with the macroalgae and are differentiated from these by their size and a lack of defined organs (although they do have specialized cell types).

  • Such yeast can comprise, but are not limited to, Saccharomyces cerevisiae,
  • Saccharomyces bayanus Saccharomyces bayanus, and Kluyveromyces sp.
  • the rotifer and brine shrimp culture system includes fiberglass tanks at a working volume of 20-2000 L each. This system is capable of producing up to 5 x 10 9 rotifers/day/tank at a density range of 200-10,000 individuals/mL or up to 10 kg brine shrimp wet biomass/day/tank.
  • the temperature is regulated in each tank by a thermostat heater at 28-32°C, depending on the rotifer strain.
  • a pH controller continuously monitors the pH in each culturing tank and 10% hydrochloric acid (HCl) is added automatically by means of a Petri pump to control the pH to between 6.5-7.0.
  • a buffer solution containing sodium hydroxymethane sulfonate is added to keep the ammonia in a non-toxic form. Slightly acidic pH of the culture medium is maintained, especially in high-density culture systems, since rotifer growth and fecundity rates are sensitive to high concentrations of toxic ionized ammonia (e.g., concentrations over 7.8 mg/L, as reported by Yu and Hirayama, 1986).
  • Food is delivered to each culture tank manually or continuously by means of a Petri dosage pump.
  • the daily amount of algal feeds and other supplements may be maintained in a chilled (0-4°C) suspension chamber, equipped with a slow mixing device.
  • Rotifers are harvested continuously in a separate harvesting tank by daily exchanging of up to one third of the culture volume and can then be further enriched with essential nutrients before being delivered to fish larvae.
  • a shortage of oxygen is expected. Therefore, pure oxygen, provided from oxygen cylinders or an oxygen generator, is diffused into each tank through air stones to maintain a minimal oxygen level at 3 ppm. Accumulation of parti culate organic matter and contaminating protozoans is anticipated at high culture densities, which may affect production and clog plankton nets at harvesting.
  • the rotifer or brine shrimp medium is continuously circulated through nylon mat filters (1 cm thick); such a simple filtration system effectively removes solid substances with only minimal losses and stabilizes the culture performance (Yoshimura et al., 1996; Yoshimura etal, 1995).
  • Brewers yeast or partially hydrolyzed baker's yeast (where at least the external layer of the cell wall is digested, either enzymatically or chemically) provide brine shrimp and rotifers with highly digestible nutrients.
  • the yeast content in the algal feed formulation ranges from 30% to 95% and, more preferably from 70% to 90% of the feed.
  • the present invention provides yeast that are accessible to the digestive enzymes of their predators, but their wall remains sufficiently intact so that the cell contents do not escape into the water prior to consumption.

  • Long chain polyunsaturated fatty acid-rich microalgae are provided as a source of essential fatty acids, especially DHA, ARA and EPA (Barclay and Zeller 1996; Cure et al. 1996; Furuita et al. 1998; Abu-Rezq et al. 2002; Place and Harel 2002a; Place and Harel 2002b).
  • the inclusion level of DHA-rich algae ranges from 0.5 % up to 50% of the feed, and more preferably from 5% to 20% of the feed.
  • DHA docosahexaenoic acid
  • Larvae ultimately acquire these fatty acids from algae, either by directly feeding on algae with high levels of polyunsaturated fatty acids or by feeding on rotifers and brine shrimp that have been enriched with algae high in polyunsaturated fatty acids (Barclay and Zeller 1996).
  • DHA-rich microalgae can be produced in fermentors utilizing sugar as a source of energy or photosynthetically. These algae are fortified with Vitamin B 12 , a vitamin essential for growth and reproduction of rotifers, during the production process to contain at least 200 ⁇ g/100 g dry matter.
  • Arachidonic acid (ARA) rich microalgae or fungi are provided as a source of essential fatty acids.
  • the inclusion level of ARA-rich algae ranges from 0.5% to 10% of the feed, and more preferably from 2% to 8% of the feed.

  • Probiotic or prebiotic bacteria e.g., Lactobacillus sp., Bacillus sp.,
  • Bifidobacterium sp., and Enterococcus sp. are added at a range from 0.01% to 5%. These bacteria function either to colonize the gut of the organism or deliver a beneficial activity or nutrient. Such probionts could relieve stress or reduce the pathogen load of the consuming animal.
  • Macroalgal extracts are also included in the formulation at a range from about 0.1 % to about 10%, and more preferably from about 0.5% to about 1%.
