Feeding system and method for apostichopus japonicas industrial aquaculture

Abstract

The invention provides a feeding system and method for apostichopus japonicas industrial aquaculture. The feeding system comprises a culture pond, a feed trough, a feed guiding pipe and a sprayer. The feeding system is characterized in that the feed trough is arranged on one side of the culture pond, the bottom of the feed trough is higher than the culture pond, the bottom of the feed trough is connected with the feed guiding pipe, the tail end of the feed guiding pipe is connected with the sprayer, an electromagnetic valve and a timer are installed at the joint of the feed trough and the feed guiding pipe, and the electromagnetic valve and the timer are connected with a control system. A spraying pipe is held manually or driven by a movable frame to move at constant speed form one end to the other end along the position above the culture pond, and apostichopus japonicas feed in the feed trough is drained into the culture pond below the spraying pipe through the feed guiding pipe based on the siphon principle. The mechanical degree is high, the culture efficiency can be improved, the labor intensity can be reduced, diseases can be reduced, the product quality can be improved, and comprehensive culture benefits can be increased.

Description

technical field [0001] The invention relates to seawater culture technology, in particular to a feeding system and a feeding method for imitating sea cucumber factory culture. Background technique [0002] Imitation sea cucumber (commonly known as sea cucumber, sea cucumber, etc.) is the most important cultured species with rich nutritional value in the northern coast, and the market demand is huge. At present, the country has developed an area of ​​3.25 million mu of imitation japonicus, with an annual output of 206,000 tons and an annual output value of nearly 40 billion yuan. It has become the leading aquaculture industry with the highest output value of a single marine species. With the continuous development of the japonicus aquaculture industry, the extended development space of outdoor pond aquaculture is gradually restricted. At the same time, it also faces the adverse effects of frequent extreme weather in recent years. The advantages of high degree of intensificat...

Problems solved by technology

Artificial sprinkling methods generally have disadvantages such as high labor intensity, time-consuming and laborious, uneven sprinkling, and inaccurate feeding amounts, which can easily cause the accumulation of residual bait at the bottom of the pond and the deterioration of the smelly bottom. stage, it is more likely to cause diseases, which directly affects the breeding effect of sea cucumbers; although feeding with feeding pumps saves time and effort, it also generally has disadvantages such as uneven feeding, waste of spraying, and affecting the internal hygiene of the workshop.
