Mixed culture method for Enteromorpha and hybrid abalone

Abstract

The invention relates to a mixed culture method for Enteromorpha and hybrid abalone. According to the invention, the density of the hybrid abalone is 400 hybrid abalones per a pond; the density of the Enteromorpha is 42.17 g / m3; the size of a culture pond is 180 cm * 150 cm * 130 cm; the hybrid abalone is hybridization progeny of Haliotis discus hannai and Haliotis discus and is cultured by adopting a net cage with a size of 43.5 cm * 33.5 cm * 14 cm and 40 hybrid abalones in each cage; every five culture cages are bound into a string with 200 hybrid abalones; the culture cages are placed in algae culture ponds, wherein two strings of abalone cages are placed in each pond; when the hybrid abalone is cultured for a week, algae is started to be introduced for mixed culture; and the algae is hanged at the center of pond surface for culturing through net covers and maintains a certain distance from the abalone cages, so culture algae is avoided from being eaten by the hybrid abalone. The invention researches the method for mixed culture of common macroalgae Enteromorpha and the hybrid abalone of Haliotis discus hannai and Haliotis discus in China, studies the influence of the algae on purification of water quality in a hybrid abalone culture pond and growth of the hybrid abalone, and provides a necessary and scientific basis for further selection of macroalgae for construction of a novel and effective abalone healthy culture mode.

Description

Technical field [0001] The invention belongs to the technical field of marine biology, and specifically relates to a polyculture method of hybrid abalone and Enteromorpha. Background technique [0002] With the continuous expansion of the scale and intensive degree of abalone farming in my country, the effects of abalone's feeding, excretion and residual bait have led to the growth of pathogens, the deterioration of the breeding environment, and the impact on the ecological environment of the shallow sea. In response to this problem, scholars at home and abroad have proposed using large seaweeds to bioremediate sea areas. Large seaweeds have certain advantages as biological filters. They are ecologically complementary to farmed animals, and can absorb nutrients and CO released by farmed animals into the water body. 2 At the same time, it produces oxygen, adjusts the pH value of the water body, and achieves ecological regulation and bioremediation of the breeding environment. In ...
