Embodiment

[0017] The selected pond is in an aquaculture base in Anhui, and the pond is a 4 mu pond. The snail and Australian lobster are mixed according to the following breeding steps:

[0018] (1) Pond management: Disinfect the pond before breeding, adjust the water quality with microbial preparations after water injection, plant hornwort algae covering a quarter of the bottom of the pond, and set up a 2.2kw aerator per 2 mu , a set of temperature regulation system to adjust the salinity of pond water to 4-6‰;

[0019] (2) Stocking management: stock 2-4cm shrimp fry in mid-April at a stocking density of 8,000 / mu; stock 2-3cm snails in mid-May at a stocking density of 4,000 / mu;

[0020] (3) Condition management: adjust the PH value of the pond water to 7.5-8.5, the dissolved oxygen to 2-4mg / L, monitor the temperature of the pond water, and use the temperature adjustment system to keep the temperature of the pond water within 22-30°C. The water flow intensity is 0.2-0.5m / s. By detectin...

Abstract

The invention discloses a freshwater feeding method of sillago sihama. The freshwater feeding method is applied to polyculture of sillago sihama and Australia lobsters. The method comprises the following breeding steps: pond management, breeding management, condition management, feeding management, pond water management and fishing. Compared with the prior art, the freshwater feeding method of sillago sihama has the following advantages: the lobsters are bred in advance until the length of the lobsters reaches 5-7cm according to the growth characteristics of the Australia lobsters and sillago sihama, so that the lobsters are prevented from being killed when the lobsters are subjected to polyculture with the sillago sihama; the sillago sihama are mainly fed after polyculture; the lobsters eat residual feeds and organisms in the aquatic plants; hornwort can increase the content of dissolved oxygen in the pond water and can also provide habitat for the lobsters; the sillago sihama are firstly fished by an ultrasonic fishing machine, so that the fishing survival rate can be greatly improved; due to the polyculture, the water quality is optimized, a breeding cost is reduced, the survival rate of the sillago sihama and the lobsters can also be improved, and the economic benefit is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for raising snails in fresh water. Background technique [0002] Sand cone fish is a small fish with delicious taste and high economic value and nutritional value. It is an important economic fish in the coastal areas of our country and is loved by consumers. It contains high-level unsaturated fatty acids DHA and EPA, and EPA has the function of lowering cholesterol. and triglycerides, DHA itself is an important substance to form brain cells, brain nerve nucleus and retina. In order to improve the harvest rate and quality of snail fish, the previous monoculture was gradually changed to polyculture of various fish, but snail Cone fish have high requirements on water quality. They are euryhaline fish. The salinity of the water body required for growth reaches 5-43, but the survival rate needs to be improved, especially when cultured in ponds with low salini...
