A water-saving nursery method suitable for bay scallops

Abstract

The invention relates to a seedling raising method, in particular to a water-saving and low-carbon seedling raising method for bay scallops. During the cultivation of bay scallop seedlings, high-concentration fresh bait is fed during the cultivation period, and photosynthetic bacteria and antibiotics are applied at intervals during the feeding of fresh bait, thereby synergistically controlling water quality, prolonging the water change cycle during scallop seedling cultivation, and improving seedling growth. Success rate. The invention provides a scientific and effective method for water-saving and low-carbon seedling cultivation of bay scallops, which greatly reduces the consumption of warming seawater during the cultivation of bay scallops, effectively reduces the emission of carbon dioxide and dust, reduces costs, protects the environment, and reduces Frequent water changes can harm the seedlings, improve the success rate of seedlings, and promote the healthy and sustainable development of the bay scallop seedlings and aquaculture industry.

Description

technical field [0001] The invention relates to a seedling raising method, in particular to a water-saving and low-carbon seedling raising method for bay scallops. Background technique [0002] Gulf scallops belong to Phalabranchia, Heterocylinda, Scallopidae, and Scallop genus. They are native to the Atlantic coast of the United States and are an important local harvested bivalve economic mollusk. The shell is fan-shaped, the two shells are almost equal, and the shell surface is dark brown or brown. Most of the bay scallops are distributed at 3-10 meters below the sea surface. They have a more pungent personality and a temperature range of -1-31°C. They stop growing below 5°C, grow slowly below 10°C, and grow faster at 18-28°C. Its salt-tolerant range is 16‰~43‰, and its suitable salt range is 21‰~35‰. Bay scallops are filter feeders, they have the ability to select the size of food, but they have no ability to select the type. The main food is organic debris, micro parti...

Problems solved by technology

At present, major changes have taken place in the environmental protection policies of the main production areas of bay scallop seedlings. The use of traditional coal-fired or oil-fired boilers is strictly prohibited. Electric heating and other more environmentally friendly methods can only be used to heat seawater, but the cost of heating seawater is more expensive. Seed production The profit margins of enterprises have been severely squeezed, and the bay scallop seed industry has been more severely tested

In short, with the transformation and upgrading of my country's marine economy and the continuous advancement of new and old kinetic energy conversion projects, the pressure of technological innovation in traditional industries such as bay scallop seedlings is increasing. The production mode with high energy consumption and high cost technology has become increasingly unable to adapt to scallop breeding. The demand for healthy and sustainable development of the industry
