Embodiment 1
[0017] Relying on the large-scale floating seine (length 100, width 50, height 12 meters) built by Laizhou Mingbo Aquatic Products Co., Ltd., according to the climate conditions and sea area characteristics of Laizhou Bay, combined with the behavior characteristics of cultured fish, the pelagic fish-red Carry out ecological mixed culture of pufferfish, benthic fish - tongue sole and rocky fish - porphyra. The half-smooth tongue sole is a bottom-dwelling flounder, which has a very low utilization rate of the middle and upper waters; the red-finned puffer can efficiently use the middle and upper waters; although the porpoise is a rocky reef fish, it has a wide range of food habits and can be used to effectively remove seine nets. The attached algae and shellfish ensure the exchange of water inside and outside the net. At the same time, red-finned puffer, semi-smooth tongue sole and grouper sea bream have wide temperature ranges and have similar temperature ranges. Therefore, acc...

The present invention provides a large -scale floating fence fish ecological mixed breeding method, which is a middle -layer fish, bottom fish and rock reef fish in the floating fence.The method of this invention makes full use of the fence farming space to achieve three -dimensional hybrid breeding, increasing the economic benefits of the breeding, and at the same time, omnivorous rock reef fish can effectively eat feed bait, or they can be eaten on the net clothes and algae to prevent it from preventing it from the web clothes to prevent it from being able to prevent it.The blocking of the mesh effectively guarantees the exchange of water in the interior and outside of the net clothes. In the process of hybridization, there will be no food phenomenon in the same middle and upper fish and bottom fish.
Description
technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a large-scale floating purse seine fish ecological mixed culture method. Background technique [0002] At present, seine culture and cage culture are the two most important farming models for the development of deep-sea culture. Compared with deep-water cage culture, large-scale seine culture has a larger volume, ranging from tens of thousands to hundreds of thousands The size varies, which is equivalent to hundreds of net cages. The breeding objects have a large space for activities, and the ecological environment is closer to the natural state. It can realize the harmonious symbiosis of multi-trophic marine organisms such as fish, shrimp, shellfish, algae, and ginseng. The quality of the breeding objects It is closer to nature and ecology. At the same time, its unit water cost is only less than 10% of the cost of aquaculture net cages. It makes full use of the a...
