2. Description of the Related Art Marine animals belonging to arthropod phylum crustaceans such as prawns, lobsters and crabs and mollusc phylum gastropods such as mica, octopus or snails and bivalves, cephalopods, and axpods are all known. Are also invertebrates, but are important as fisheries resources, and many are industrially farmed. The cultivation of these aquatic animals is performed by dividing a natural sea surface, releasing larvae or larvae of the animals to be cultivated in the water area, and administering live feed, compound feed and the like thereto. The environment of the marine area in which it is cultured is very important for farmed animals. In particular, the reduction of dissolved oxygen in cultured seawater causes a great deal of damage to farmed animals. One of the factors that reduce dissolved oxygen in cultured seawater is a rapid rise in seawater temperature. When the water temperature increases, the dissolved oxygen concentration in the water decreases, and conversely, the metabolism of marine invertebrates is activated, so that the oxygen consumption increases.
Moreover, fish invertebrates, unlike fish, cannot move inhabited areas even if their habitats deteriorate, so this imbalance causes the fish invertebrates to die. A further factor in reducing dissolved oxygen is the contamination of the sea area by the remaining feed. Reducing the amount of feed can reduce the amount of residual food, but it is undesirable because food shortages can lead to cannibalism and reduced growth, and farmers are struggling to determine the appropriate amount of feed. Therefore, a breeding method for marine invertebrates and a feed therefor that can suppress the decrease in the dissolved oxygen concentration of the cultured seawater and eliminate mortality are desired.

[0010] The mixed feed for marine invertebrates of the present invention does not disperse in water and can be formed and processed into a size and shape optimal for feeding of marine invertebrates. The combined feed preferably has a specific gravity in water of 1.00 ± 0.10. Further, it is preferable that the disintegration degree of the compound feed in water is 10% by weight or less in 24 hours. Means such as spray drying, ventilation drying, and heat extrusion are used for the forming process. Heating, kneading, and other operations are usually performed during the shaping of feed, which may lead to deterioration and ineffectiveness of nutritional components.However, the mixed feed for marine invertebrates of the present invention contains proanthocyanidins. Therefore, the product is extremely stable and can prevent deterioration and invalidation.

Good results are obtained at both rates. This is presumably because proanthocyanidins have many phenol groups, and their hydroxyl groups supplement active oxygen free radicals, so that the compound feed of the present invention has a strong ability to scavenge active oxygen. Furthermore, since proanthocyanidins have an immune system activating effect, it is considered that this is because the immune system of breeding marine invertebrates was activated.

EXAMPLE III As ultrafine particle feed for bivalves, casein 25%, krill 10%, fish meal 10%, beer yeast 20%, egg yolk 10%
%, Squid oil 11%, vitamin mix (Halber formula)
2%, Mineral Mix (Halber formula) 3%, Applephenone (50%) 1%, Vitamin C 0.1%, Carrageenan 8% are mixed, and 3 times the amount of water is added and kneaded to make a slurry And this is inverted 13
A test feed having an average particle size of 50 μm was obtained by spraying and drying in air at 5 ° C. using a rotary nozzle. In the same manner, a control feed containing 1% of dextrin as a bulking agent instead of applephenone was prepared, and the storage stability of the two was compared and examined. Test feed and control feed at room temperature 30
After standing for 30 days in an artificial weather chamber at 95 ° C. and a relative humidity of 95%, the fate of vitamin C in the product was determined by analysis. The results are as follows. Immediately after production 30 days after production Test feed (%) 0.18 0.18 Control feed (%) 0.18 0.06 Next, on the 200th day, 100 scallop shells having a shell length of about 8 cm were passed through the upstream and downstream circulating water. Housed in an aquarium with 8
Each time, the test feed and the control feed in an amount corresponding to about 10% of the body weight were administered, and the growth of scallop was measured at water temperature of 16 ° C.
Considered in ° C. The results are as follows. In addition, the specific gravity of the feed in water in both sections was 1.008, and there was no difference in the floating properties. At the start of the test 30 days after (water temperature 16 ° C) 30 days after (water temperature 28 ° C) Test feed section Shell length 8cm Shell length 8.32cm Shell length 8.11cm Control feed section Shell length 8cm Shell length 8.30cm Shell length 8.0cm In the water tank at a water temperature of 28 ° C. in the control feed group, 96 scallop shells died, and the surviving individuals were so weak that they could not close the shells sufficiently. On the other hand, 25 scallop shells died in the water tank at a water temperature of 28 ° C in the test feed plot, but the remaining shellfish were relatively healthy. In addition, the disintegration degree of the feed was 7.5% in the test feed group and 7.8% in the control feed group, all of which were 1%.
0% or less.

Industrial Applicability The present invention is effective in preventing the deterioration of the breeding environment due to feeding encountered when raising larvae and larvae of marine invertebrates such as prawns, lobsters, crabs, squids, octopuses, and shellfish. A method for breeding marine invertebrates is provided. By administering the compound feed for aquatic invertebrates of the present invention to larvae and larvae of aquatic invertebrates, stress of the animals at high water temperature can be controlled, and immunity to harmful microorganisms can be improved to improve healthy adults. Can be obtained.
Therefore, the method of breeding a marine invertebrate with the compound feed of the present invention, that is, the method of breeding a marine invertebrate of the present invention is as follows.
Even at a high temperature of 8 ° C. or higher, good results are obtained for both the growth rate and the survival rate. INDUSTRIAL APPLICABILITY The present invention is extremely useful for aquaculture production of aquatic invertebrates.
