Culter Alburnus Of Xingkai Lake Cultivation Mode And Acute Toxicity Test Of Drug Research

Xingkai lake become warped lips Bo (Topmouth culter) is become warped lips Bo (culter alburnus) in a geographic populations, also called the xingkai lake big white fish, fish is a rare economy.Its whiteness, tender meat, taste delicious, was as a fish in the first grade and favored by people.By years of predatory fish, the water level decline and environmental factors, xingkai lake become warped lips Bo have fewer wild population.In order to conserve fish resources and continuously meet the needs of people’s life, xingkai lake become warped lips Bo artificial aquaculture has developed rapidly, has become especially important in heilongjiang province in the northeast of breeding objects.Xingkai lake become warped lips Bo intensive aquaculture experiment is to ask Gao Xingkai lake become warped lips Bo intensive breeding level.This experiment by xingkai lake become warped lips Bo intensive cultivation experiment was carried out, in order to further promote xingkai lake become warped lips Bo farmed, explore become warped lips Bo pond farming productive technology, help to improve the pond farming economic benefits.In recent years as the xingkai lake become warped lips Bo artificial breeding technology breakthrough, the increase of market demand, breeding, xingkai lake become warped lips Bo has gradually rise.At present the study of xingkai lake become warped lips Bo mainly concentrated in xingkai lake become warped by only mouth Bo cultivation, breeding and the development of embryo, seedling cultivation, fish breeding, and meat quality and flavor, and so on.But the drug trial of xingkai lake become warped lips Bo rare reports.Therefore, this test by xingkai lake become warped lips Bo young fish acute toxicity experiment of commonly used fishing with drugs and dosage of safety research, aimed at efficient intensive healthy farming xingkai lake become warped lips Bo provide technical support.Thesis mainly from two aspects of xingkai lake become warped lips Bo was studied, and the first pond breeding, different specifications of the xingkai lake become warped lips Bo and different sets of a mode of study;Second several common fishery drugs in xingkai lake become warped lips Bo larvae first acute toxicity test, the results are as follows:(1) the wild xingkai lake become warped lips Bo is the main pelagic fish on natural bait, we still have some difficulties in large-scale intensive in the pond farming, with constant xingkai lake become warped lips Bo artificial breeding technology breakthrough, through the training can fully feeding compound feed.Become warped lips Bo of dissolved oxygen in water body demand is higher, but at the same time can low dissolved oxygen, can be intensive, high density in the pond.This test after the pond aquaculture different specifications of the xingkai lake become warped lips Bo and breeding mode, achieved the expected target, it has reference and guidance for the broad masses of farmers.(2) the test adopts crude protein is40%compound feed, bait coefficient of1.56, xingkai lake become warped Bo mouth to feed the crude protein content of the demand is higher, about40%～40%, crude protein content in feed close to the experiment, the bait coefficient on the high side.Xingkai lake become warped lips Bo feed protein content should be more than43%, to increase production, become warped lips Bo colleagues to improve the commodity price of fish, increase the breeding benefit.(3) on the large size fish pond is by Lord raise xingkai lake become warped lips Bo fish production and economic benefit is the key.Because relatively late xingkai lake become warped lips Bo breeding season (from June to July), on the basis of conventional seedling cultivation method of farmed fish, of aquaculture ponds feeding to need2years time, can’t be commercial fish in aquaculture.So can develop the low density of the large size fry method, cultivate15cm above the large size of xingkai lake become warped lips Bo species, in order to make sure the pond aquaculture xingkai lake become warped mouth Bo demand.(4) in the process of the cultivation experiment, xingkai lake become warped lips Bo basically feeding diseases occur, this suggests that the variety of disease resistance is strong, suiTab. for high-density intensive farming pond.By using three kinds of commonly used for aquaculture drugs xingkai lake become warped lips Bo young fish acute toxicity experiment was carried out, the chlorine dioxide, povidone iodine, chlorine, bromine different cyanuric acid on the safety of the xingkai lake become warped lips Bo larval concentrations were2.58mg/L,3.95mg/L,0.51mg/L.Xingkai lake become warped lips Bo sensitivity to the three drugs in the order:bromine chloride different cyanuric acid> chlorine dioxide> povidone iodine.Xingkai lake become warped lips Bo domestication of the sensitivity of the chlorine dioxide than other breeding shorter fish is high, the lower the sensitivity of povidone iodine.Although the xingkai lake become warped lips Bo resistance is better, but also should pay attention to during the process of breeding careful with drugs.
