Acanthogobius ommaturus Richardson ecological breeding method

Abstract

The invention discloses a Acanthogobius ommaturus Richardson ecological breeding method. The Acanthogobius ommaturus Richardson ecological breeding method comprises the steps of selection of parent fishes, control of the stocking number, selection of the pond size, winter cultivation management and fry collection. The method is characterized in that the parent fishes with the weight of 100-250 grams are selected from November to December and put into a pond with the size of 3-9 mu for cultivation, wherein the proportion of females to males is 1:1, and the stocking number per mu is controlled to 3-5; 1-2 kilograms of live Exopalaemon carinicauda is put in per mu in the period of winter cultivation as fodder of the parent fishes, water is changed at regular intervals to keep the good water quality condition, the water level of the pond is maintained at 1.25 meters, and the salinity is maintained at 5 %. or above; fry sampling is conducted after the next April 20th, the growth situation is examined, and fries are dispersed in time after growing to 2.5 centimeters or above.

Description

technical field [0001] The invention relates to a method for raising seedlings of the goby. Background technique [0002] Spot-tailed goby (Acanthogobius ommaturus Richardson), also known as spear-tailed goby, belongs to Perciformes, family Goby, and genus Goby. It is an annual warm-temperate offshore bottom fish, adapting to temperature and salt They are widely distributed in coastal areas, harbors and estuaries. They like to inhabit muddy or sandy bottom waters. They are a kind of carnivorous fish with fierce habits. They mainly feed on juvenile fish, shrimps, crabs and small In molluscs, it is also common for large individuals to eat small ones among the same kind. Gobies are larger and grow faster. Adults can grow to 100g-250g in the current year, and some individuals can grow to about 500g at the end of the year. Its meat is tender, boneless, high in yield, and delicious. It is well known and favored by the public and has certain economic value. Although there is a c...

Problems solved by technology

Since the 1970s, some scholars in my country have successively carried out some biological research on the goby. In recent years, its breeding and breeding have gradually developed, but there are few reports on successful cases and mature technical experience, especially However, there have been no reports about successfully obtaining ecological seedlings of the goby by selecting suitable size parent fish, controlling the stocking quantity, and creating suitable breeding conditions after overwintering cultivation based on its reproductive characteristics.
