Problems solved by technology

This kind of feed is incomplete and deficient in nutrients, and does not consider the feeding characteristics of swimming crabs. The feeding of swimming crabs is to use the big claws to clamp the food, and the bait is too long, which is easy to break and cause loss.
[0004] In addition, usually the swimming crabs are fed evenly in the whole pond. After long-term breeding observation and experimentation, it is found that the distribution of swimming crabs at the bottom of the pond is not uniform due to the environment of the breeding pond, the weather environment, and its own health. Swimming crabs live intensively in a certain area of ​​the breeding pond, but the feeding amount is too small or excessive, resulting in local shortage of bait or a large amount of residual phenomenon. Therefore, it is necessary to carry out more refined breeding management, which is conducive to improving the utilization rate of bait

Abstract

A feed for portunus trituberculatus, and preparation and use methods for the same. The feed is composed of 25-35% of minced fish, 64-74% of a fermented mixture component and 1-1.5% of sodium alginate. The fermented mixture component is prepared by fermenting the following components, including 23-27% of fishmeal, 45-55% of soybean meal, 18-22% of flour, 0.5-1.5% of seaweed powder and 3-5% of shrimp shell powder, with lactobacillus plantarum, yeast and bacillus subtilis according to the ratio of 2.9-3.1:0.9-1.1:0.9-1.1. The diameter of the feed is 4-6 mm and the length is 1-2 cm. During breeding, more than four feed benches are disposed in one breeding pool strictly, wherein each feed bench covers a certain breeding zone, and feeding quantity is strictly controlled according to residual feed in the feed bench. If the feed leaves in a feed bench, the feed adding quantity to this zone is reduced in the next day, while the feed adding quantity to the other zones without left feed is correspondingly maintained or increased, thereby achieving regional fine feeding management in the breeding pool. The feed is simple in process, has good palatability, is more environment-friendly than single fresh and alive feeds, and is also higher in utilization rate.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a feed for Portunus trituberculatus and a preparation and use method thereof. Background technique [0002] Portunus trituberculatus, commonly known as Portunus trituberculatus, is mainly distributed in Liaoning, Hebei, Tianjin, Shandong, Jiangsu, Zhejiang, Fujian and other sea areas in my country. It is one of the most important export products in China, and the scale of breeding has remained high. At present, the bait for swimming swimming crabs mainly depends on the catches of nets, and the commercial compound feed is still in the experimental stage. Among them, the net catches are not stable in quality and easy to be corrupted, so their utilization rate is low, and because farmers often throw small miscellaneous fish directly into the breeding ponds for feeding without any treatment, it is easy to over-feed or under-feed. Residual bait can easily cause water quality to det...
