Method for feeding sea cucumbers with proportioned bait in suspending cage breeding mode

Abstract

The invention relates to a method for feeding sea cucumbers with proportioned bait in a suspending cage breeding mode, and belongs to the field of aquiculture. The method adopts powdery sea cucumber compound feed, pre-gelatinized starch and drained soaked kelp, and is characterized in that the drained soaked kelp is cut into small slices to be placed into a non-toxic container; the powdery sea cucumber compound feed, the pre-gelatinized starch and the drained soaked kelp are mixed according to a weight ratio of 1 to 2 to 8; during mixing, the sequence needs to be taken into consideration, that is firstly, the powdery sea cucumber compound feed and the drained soaked kelp slices are mixed uniformly, and then the mixture is uniformly mixed the pre-gelatinized starch, wherein in the process, the flouring of the pre-gelatinized starch and stirring are operated at the same time, and the stirring cannot be stopped until the mixture is uniform and the powdery sea cucumber compound feed is uniformly adhered to the surfaces of the kelp slices; during feeding, suspending cages are pulled out from water, bait feeding windows at all layers of each cage are opened, and the uniformly mixed bait is fed according to the food intake of the sea cucumbers.

Description

technical field [0001] The invention relates to bait ratio feeding of sea cucumber hanging cage culture in the technical field of aquaculture. Background technique [0002] At present, my country's sea cucumber culture has reached scale and industrialization, and has become one of the pillar industries of my country's mariculture. Sea cucumber culture has also developed from traditional pond culture to factory culture, net cage culture, hanging cage culture, caisson culture, etc., but At present, the largest output and the highest output value are mainly for sea cucumber farming. The reason is that seawater in natural sea areas is rich in nutrients. Simply feeding some kelp can meet the needs of sea cucumber farming. There are few diseases, high survival rate, and fast growth. , but when sea cucumbers are transferred to indoor factory culture or indoor hanging cage culture, due to the small amount of nutrients in seawater and the small amount of water exchange, the micronutrie...

Problems solved by technology

In recent years, due to the increase in the cultivation area of ​​sea cucumbers, natural sea mud can no longer meet the needs of cultivation. Therefore, the sustainable development of sea cucumber cultivation cannot be carried out by using traditional methods. Therefore, farmers use sea cucumber powdered compound feed to replace it. , but if the powdered
