Problems solved by technology

This method has achieved good results in the breeding of elephant trunk spats, but the disadvantage of this method is that water is added all the time during the middle cultivation process without changing the water, so it is difficult to control the bait. Not good, it often causes the overgrowth of unicellular algae bait, which greatly affects the normal growth of elephant-nosed mussels

Abstract

The invention relates to a method for intermediate cultivation of a juvenile lutrariasieboldii reeve in an outdoor cement pond, and belongs to the technical field of cultivation of aquatic animals. A cement cultivation pond can be indoor or outdoor; an outdoor pond needs a frame to be put up and a sunshade net is covered at the top of the outdoor pond. According to the method, an overhead cultivation bed consisting of a bridge type support frame, a sand bed and other auxiliary facilities is arranged at the bottom of the cement cultivation pond; after the arrangement is completed, the cultivation pond is sterilized and soil-filtered sea water is introduced, wherein the water is 40 to 50 cm higher than a sand surface; juvenile lutrariasieboldii reeves which are 1 to 3 mm in shell length are fed according to a density of 3,000 to 5,000 / m<2>; monodus subterraneus and natural algaes from the shrimp pond are supplied for 2 to 4 times every day, and the water is changed twice thoroughly or 200% convection water is supplied. Subjected to intermediate cultivation for one month, the juvenile lutrariasieboldii reeve is as long as 2.0 to 2.5 cm and as heavy as 2 to 3 g so as to meet the requirement. The lutrariasieboldii reeve intermediately cultivated by the method is high in survival rate and growth speed and low in cost, and the breeds of lutrariasieboldii reeve are convenient to collect, therefore a large-scale intermediate cultivation of juvenile lutrariasieboldii reeve is realized and the economic benefit of breed production of lutrariasieboldii reeve is greatly improved.

Description

technical field [0001] The present invention relates to a method for intermediate cultivation and culture of juvenile shellfish, in particular to a kind of elephant-nosed mussel (Clam shishii, Lutrariasieboldii The invention discloses a culture method for cultivating juvenile shellfish in an outdoor cement pond, belonging to the field of aquatic animal breeding. Background technique [0002] elephant-nosed mussel Lutrariasieboldii Reeve), belonging to Lamellibranchia, Heterodonta, Veneroida, Mactracea, Mactridae, Otter clam ( Lutraria ). The elephant-nosed mussel is a warm-water shellfish, distributed in tropical-subtropical sea areas. It is a bottom-dwelling shellfish that likes to live in the intertidal zone to 10m deep sand or sandy muddy seabed. The water temperature in the living sea area is 8-32 ℃, and the salinity 11.50-33.00, pH value 8.2-8.4, transparency 4-7m, food is mainly benthic diatoms and organic debris, has the habit of diving in sand, and has strong e...
