Example Embodiment

[0019] Example 1

[0020] A method for culturing South African penaeus monodon with high salinity and high density in a high-level pond, including temporary cultivation in a shrimp fry workshop, high-level pond culture management and staged fishing;

[0021] Step 1: Combine the cultivation mode of the factory workshop, and cultivate the newly purchased South African monodon seedlings for 20 to 30 days; , the salinity difference is less than 5;

[0022] Step 2: Add high-salinity seawater to the factory culture pond every other day. The increase of salinity is controlled within 1-2‰, the final salinity reaches 35‰, and the water temperature should gradually rise to 28 to 29°C. The pH is 8.1-8.5; the water temperature, pH value and other indicators remain relatively stable throughout the temporary incubation period;

[0023] Step 3: After the temporary culture starts, sprinkle the micro-ecological bacteria preparation into the culture water every 3 days, and the amount of splas...

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...
