Problems solved by technology

The previous method of manually fishing live bait for shrimp ponds with nets was heavy workload and low efficiency. Moreover, the bait specifications were different, there were many algae, and there were often large fish and shrimp mixed in, so it was difficult to separate them.

Abstract

The invention relates to a method for collecting live bait for raising squid seedlings and temporarily cultivating indoors. A floating net cage made of a net is used as a bait collection net cage, and the floating net cage is used as a temporary bait raising net cage and a bait collection net cylinder; A bait casting tray equipped with lighting equipment is hung on the four corners of the net cage; the bottom of the bait temporary storage cage is equipped with micro-hole oxygenation; , the other end of the bait collection net cylinder is connected to the water outlet of the floating pump, and the floating pump is suspended in the bait collection cage; the floating pump is turned on to collect live bait and then temporarily raise it. The invention can realize rational utilization of live baits in shrimp ponds, meet the needs of large-scale seed breeding of squid, reduce labor costs, and has simple technical operation, and is suitable for supplying a large amount of live baits in the process of fully artificial squid seedling breeding.

Description

technical field [0001] The invention relates to a method for collecting and feeding bait, in particular to a method for collecting live bait for raising squid seedlings and temporarily cultivating indoors. Background technique [0002] With the breakthrough of artificial breeding technology of golden squid, tiger squid and squid mansoni, the artificial breeding of cephalopods may set off a new wave of aquaculture. In the process of cultivating squid seedlings, the supply of a large amount of high-quality live bait has become a bottleneck for the success of squid seedling cultivation. Under normal circumstances, squid seedlings must eat a large amount of live bait within 10 days after they emerge from the film, otherwise they will die in large numbers; and a large number of mysis and copepods naturally breed in the shrimp breeding pond, which can meet the needs of squid seedlings for live bait. need. Previously, the method of manually fishing live bait for shrimp ponds with...
