Method for culturing South African sugpo prawns by higher-place pond, high salinity and high density

Abstract

The invention discloses a method for culturing South African sugpo prawns by a higher-place pond, high salinity and high density, and belongs to the technical field of marine culture. The method includes South African sugpo prawn seed workshop temporary culture, higher-place pond culture management, scallop cage throwing in the higher-place pond and fishing by stages. By combination of factory-like workshop culture modes, the South African sugpo prawns are salinized and temporarily cultured, microecological bacteria are reasonably used in the culture process, waste scallop cages are thrown into the higher-place pond, the sugpo prawns are fished by stages at a late culture stage, the South African sugpo prawns can adapt to high-salinity water, water quality can be ensured at the late high-density culture stage, and the method is of great significance for increase of survival rate at an earlier stage, guarantee of culture water quality and yield improvement.

Description

technical field [0001] The invention belongs to the technical field of marine aquaculture, and particularly relates to a method for culturing South African penaeus monodon with high salinity and high density in a high-level pond. Background technique [0002] South African monodon (Penaeus Monodon), also known as diamond shrimp, monodon king, belongs to Arthropoda, Decapoda, Penaeidae, Penaeus. Originally from Mozambique, Africa, the shrimp is large in size, bright red in color, good in taste, rich in nutrition and high in price, and is favored by people. [0003] In recent years, due to the serious disease of Penaeus vannamei, the breeding work is more difficult, so efforts are made to seek new breeding species. South African monodon has strong disease resistance, short growth cycle, low feed coefficient, high yield, and adapts to a wide range of salinity, generally 10 to 30‰, and gradually attracts people's attention. Shandong Province has a wide saline-alkali area and h...

Problems solved by technology

However, since the salinity of seawater in many saline-alkaline areas reaches 40‰ or even higher, and the highest salinity of Penaeus monodon does not exceed 30‰, the purchased seed can easily lead to death after being stocked in high-level ponds, and the high-density breeding until the later stage of breeding , the water quality has seriously deteriorated, affecting the growth of South African prawns
