Problems solved by technology

Artificial seedling and breeding have become an important means of resource replenishment, but there are no related reports on indoor factory artificial seedling and cultivation of cephalopods in my country.
At present, circular ponds are used for cultivation experiments in foreign countries, but the disadvantages are that the individual density of cultivation is very low, and the consumption of purified seawater is large; in addition, because squid and other cephalopod larvae like to crawl on the bottom of the pond without feeding, it is difficult to observe them growth conditions, and the operation is inconvenient, it is acceptable only in the laboratory for experimental research, but for large-scale production, not only the production and operation costs are greatly increased, but also the operation and management are cumbersome, and it is not suitable for the requirements of industrial seedling cultivation

Embodiment Construction

[0009] When implementing the method of the present invention, at first determine the diameter of used floating cage 8 tulle meshes according to the size of cuttlefish ovum diameter and larvae. The length of the casing 2 of net cage 8 is about 1 meter, and width is slightly less than the width of nursery pond 7. Top support 1 is longer than bottom support 4, can ride on the pool wall of nursery pool 7; 2 side stone pendants 3 of the front and rear sides of net cage 8 ride on the outside of the pool wall of nursery pool 7 during use, play straightening The effect of cage 8. The size of the bottom stone pendant 5 and the side stone pendant 3 should straighten the net body 2 and be advisable to stretch out. Floating net cage 8 is put into nursery pond 7, and water level remains on the 2 / 3 place of net cage height. Net cage 8 also will adopt potassium permanganate to clean before use. Put 7-9 floating cages 8 in the abalone nursery pool 7 (length×width×depth: 10m×1m×0.6-0.8m). ...

Abstract

A method for incubating the planktonic shellfish and culturing its larvae includes collecting its fertilized ova along with their attachments, hanging them from a supporting frame for development, transferring them in netted case, inculating in flowing water while aerating, and culturing their larvae in flowing water while aerating.

Description

technical field [0001] The invention relates to a method for raising shellfish seedlings in the field of aquaculture, in particular to a method suitable for high-density hatching and larvae cultivation of swimming shellfish such as squid. Background technique [0002] Squid belongs to swimming shellfish, is an important economic cephalopod in my country, and occupies an important position in the national fishery. Due to overfishing, natural resources have been quite scarce. Artificial breeding and breeding have become an important means of resource replenishment, but there are no relevant reports on indoor factory artificial breeding and cultivation of cephalopods in my country. At present, circular ponds are used for cultivation experiments in foreign countries, but the disadvantages are that the individual density of cultivation is very low, and the consumption of purified seawater is large; in addition, because squid and other cephalopod larvae like to crawl on the botto...
