Description

Lure the mandarin fish fish culture net cage of collection wild fishes

Technical field

The utility model relates to aquaculture field, specifically is the mandarin fish fish culture net cage that lures the collection wild fishes.

Background technology

Mandarin fish is a kind of high-quality fresh-water fishes, in natural water area, be feed food with fresh and alive wild fishes, even propagating artificially under the condition, also be the live fish and shrimp of ingesting be main, culturing mandarin fish must have enough wild fisheses or low-value freshwater fish fingerling deposit, ingests with the supply mandarin fish, wild fishes is under-supply, influence mandarin fish and normally ingest and grow, will culture to mandarin fish and make troubles, the fresh and alive feed fish of therefore need throwing something and feeding continually ingests for mandarin fish.

Summary of the invention

For solving feed fish supply problem, the utility model has designed the mandarin fish fish culture net cage that lures the collection wild fishes.

The technical solution of the utility model is: the mandarin fish fish culture net cage that lures the collection wild fishes, it is characterized in that: the tank wall of net cage is designed to double-deck etting, outer etting mesh is bigger, internal layer etting mesh is less, 50 centimetres of ectonexine etting spacings, at the net cage wall several conical net tubes are set, a conical net bigger end opening is on outer etting, a less end opening is on the internal layer etting, and in taper shape net tube, arrange and fall palpus in the net tube, arrange on the internal layer etting net cage internal layer tank wall fall must, be convenient to wild fishes and enter net cage, and mandarin fish and wild fishes can not be escaped from outside the net cage.

The described water surface top that lures the mandarin fish fish culture net cage central authorities of collection wild fishes arranges one or several the energy-conservation collection lamps that lure, and is used for luring night the collection wild fishes.

Beneficial effect: the cage culture mandarin fish of adopting the utility model design, open night and lure the collection lamp, throw in net cage and spread bait daytime, wild fishes lures under the collection bait, light, enters net cage, for mandarin fish provides the feed fish, because double-deck palpus is arranged, mandarin fish can not escape from net cage, and outer etting can shield, and can support conical net tube again; The utility model is economical and practical, lures the collection wild fishes effective, reduces throwing something and feeding of feed fish, can reduce aquaculture cost, improves the mandarin fish culture benefit.
