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...

Abstract

The invention provides a method for fishes ecological mixing breeding in a large scale floating purse net. The method comprises the steps of breeding pelagic fishes, benthic fishes and rockfishes in the floating purse net. The method takes full advantage of breeding space of the floating purse net, achieves the three-dimensional mixing breeding, and increases breeding economic benefits; meanwhile,the omnivorous rockfishes can effectively ingest residual feeds, can also ingest shells and alga attached to the net, avoids blocking meshes, effectively guarantees waterflow exchange of the inside and outside of the net, and phenomenon of the rockfishes fighting for food with the pelagic fishes and the benthic fishes does not occur in the mixing breeding process.

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...
