Sepia lycidas fry breeding method

Abstract

The invention relates to a Sepia lycidas fry breeding method, belonging to the field of aquatic fry breeding. The method specifically comprises the following five steps of: fishing of parents, temporary culture of the parents, acquisition of eggs, hatching of the eggs and breeding of fries, wherein sexually mature parent Sepia lycidas are selected and put into a water pond, temperature, salinity and stocking density are controlled, the water quality is kept and alive small fish and shrimps are fed for temporary culture; the parents with eggs are put into egg laying ponds in proportion and fertilized eggs are collected periodically; the eggs of the same batch are put into a hatching pond for hatching; embryos to be hatched soon are collected and put into breeding ponds, the area of each breeding pond is 10-15 square meters, the water temperature is 20-30DEG C, the seawater salinity is 25-35, the stocking density is 200-400 fries per square meter, and the fries are fed for the first time after 6-12 hours from the time when the fries are hatched and get out of embryonic membranes; and after the mantle length of the fries is more than 1.5cm, the fry breeding process is completed and the fries are moved out. The breeding method has the advantages of high survival rate, few diseases, rapid growth, easiness in operation and high success rate, and is suitable for large-scale breeding.

Description

technical field [0001] The invention relates to a method for cultivating seedlings, in particular to a method for cultivating squid seedlings of Pseudomorpha squid, belonging to the technical field of squid cultivation. Background technique [0002] The carcass of the squid is shield-shaped, and the carcass length is about twice the carcass width; the back of the carcass has some eye spots interspersed with many thin horizontal stripes. The meat fins are relatively wide, the maximum width is slightly less than a quarter of the carcass width, located on the entire edge of both sides of the carcass, and separated at the rear end. [0003] The squid is distributed in the Indian Ocean-West Pacific area, and often inhabits places with a water depth of 15-100m. It is large in size, short in reproduction cycle, fast in growth, delicious in meat, high in protein content, and has a wide range of comprehensive utilization. An excellent variety with high value.
