In view of this, the ecological fitness characteristics of the proliferation and release groups and influence factors and optimization measure research of the ecological fitness characteristics become hot spots in the proliferation and release basic research field.
Research shows that the ecological fitness of artificially-bred seedlings to natural water bodies is obviously lower than that of wild individuals of the same species, and the method is specifically shown as follows: the artificial propagation seedling seeds have weak capability of predating natural baits, poor capability of resisting stress of releasing operation and low capability of escaping enemy after entering natural water, and further the survival rate after releasing is obviously lower than that of the same wild population; meanwhile, the individual proportion of the artificially-bred seedlings in the natural water body is relatively small, the individual fertility is low, and the death rate of the offspring in the early life history stage is high, so that the reproductive supplementation capability of the artificially-bred seedlings in the natural water body is relatively weak.
The black sea bream is a rare marine economic fish, is also an important mariculture object and a breeder and release fish species, has reef-approaching property and is favored to inhabit a reef substrate sea area. The behavior tendency of the reef-seeking running fish to approach to the reef body is an external reflection of the reef-seeking strength, has important significance on requirements of predation, enemy avoidance, competition and the like of the reef-seeking fish in the growth, development and propagation processes, and determines whether the reef-seeking running fish can adapt to complex habitat in the field to a certain extent, so that the reef-seeking running fish can survive and grow better.
The environment capacity enlargement means a treatment method for intentionally increasing the complexity of the water environment so as to reduce the inadaptation behaviors of fishes, thereby realizing the improvement of the welfare of the cultured fishes. Research shows that the environmental capacity enlargement can have a plurality of effects on the behaviors, physiology and growth of animals, can enhance the hiding, competing and predating capabilities of the animals, and can improve the survival rate of domestic animals in the field. Therefore, the artificial breeding black sea bream fries are subjected to corresponding natural water survival simulation training, the anti-stress capability and the natural bait predatory capability of the fries are improved, the ecological fitness and the survival rate of the released fries are improved, and the artificial breeding black sea bream fries have extremely important significance in improving the proliferation and release effects. However, the current research on the environment and the capacity enlargement of the black sea bream is less, and the traditional black sea bream seed cultivation and release method has more defects, so that the result not only causes the waste of larger manpower, material resources and financial resources, but also seriously influences the release efficiency of the black sea bream and the sustainable utilization of the black sea bream resources.
