Method for culturing sinonovacula constricta in high-density prawn culturing tail water

Abstract

The invention discloses a method for culturing sinonovacula constricta in high-density prawn culturing tail water. The tail water drained in the high-density prawn culturing process is taken as nutritive salt for culturing algae; when the prawn culturing tail water is drained into a sinonovacula constricta culturing pond, a spreading cultivation biological agent is splashed for detoxification, the prawn culturing tail water is added according to the concentration of the algae in sinonovacula constricta culturing water, besides, an aerator is matched, sinonovacula constricta is prevented from oxygen deficit; a water pump is adopted between the prawn culturing pond and the sinonovacula constricta culturing pond to extract the prawn culturing tail water, the water in the sinonovacula constricta culturing pond is pumped into a standby reservoir after purification, and a water source is provided for the prawn culturing pond. The tail water drained in the high-density prawn culturing process is cultured and detoxified, so that nutrient salt and toxic substances in the tail water are reduced, and required nutrient salt is provided for culturing of bait for ingestion of cultured sinonovacula constricta, the sinonovacula constricta culturing water is pumped into the standby water storage pond after purification, the water source is provided for the prawn culturing pond, the cost is saved, balance of the whole ecological system is facilitated, and stable and efficient culturing of prawns and sinonovacula constricta is realized.

Description

technical field [0001] The invention relates to the field of cultivation, in particular to a method for cultivating razor clams with high-density shrimp tail water. Background technique [0002] Penaeus vannamei culture in full-steel greenhouses, due to the high stocking density and the need to feed a large amount of compound feed, due to the accumulation of residual bait, feces, shrimp shells, etc., only by changing a large number of water from time to time during the entire breeding process can the water quality be kept stable . Therefore, in the middle and late stages of greenhouse cultivation, a large amount of N, P and other nutrient salts in the water are changed, that is, eutrophic water, which is harmful but not beneficial to shrimp cultivation. But this kind of water is the best source of nutrition for ponds where razor clams are cultured. Because, a large amount of fertilizer and water are needed in the culture process of razor clams, and benthic diatoms and othe...

Problems solved by technology

This is because a large amount of fertilizer and water are needed in the cultivation process of razor clams, and benthic diatoms and other razor clams prefer to eat bait, while the cost of applying organic fertilizer in the traditional cultivation process of razor clams is very high
