Abstract
The invention discloses an overwintering method for golden pomfret. The golden pomfret belongs to warm water fish, and is suitable to grow at the water temperature of above 23 DEG C, so that the breeding period of the golden pomfret is between March and October, and the golden pomfret is difficult to overwinter. According to the overwintering method for the golden pomfret, the aspects of (1) fish fry throwing time, (2) feeding bait, (3) resistance enhancement, (4) net cage arrangement, (5) later feeding and the like are combined with a measure of adjusting the in-vitro environment of sea fish by a multi-vitamin solution, so that the overwintering resistance of the golden pomfret is improved; after the measure is taken, the overwintering mortality rate of the golden pomfret is reduced below 2 percent from over original 10 percent, the culture benefits are improved, fresh golden pomfret can appear on the market during a marketing slack season of the golden pomfret, and the added breading value is improved.
Description
Technical field
The present invention relates to the wintering method of golden butterfish, belong to sea and to breed fish cultural technique field.
Background technology
Gold butterfish is water warm pelagic fishes, oppressing delicate delicious flavour, is famous and precious edible fishes, and golden butterfish ingests artifical compound feed, growth rate is rapid, therefore, become coastal waters and mainly cultivated one of fingerling, be adapted at cultivating in net cage, gold butterfish is because be warm water fishes, be adapted at the water temperature growth of more than 23 DEG C, so the cultivation phase of golden butterfish is all in 3-10 month, golden butterfish is difficult to survive the winter.Because the cultivation of current golden butterfish is all adopt cage culture, at wealthy wide large marine networking case, can not be improved the temperature of breeding water body by the mode of heating, therefore, comparatively greatly, cultivation risk of surviving the winter is high for golden butterfish cultivation climate and Water Temperature.Less in winter-spring season gold butterfish landings, the market price is higher, if make golden butterfish survive the winter smoothly, in the winter time also can normal growth or maintenance, and good economic benefit will be produced.Therefore, provide a kind of method that the triumph of golden butterfish is survived the winter, being a kind of technological progress for golden butterfish cultivation, is also the useful measure improving culture benefit.
Summary of the invention
The object of this invention is to provide the wintering method of golden butterfish, utilize comprehensive cultural method, improve the cold tolerance of golden butterfish, survive the winter smoothly, overcome the deficiency that traditional cultural method gold butterfish cannot survive the winter.
The realization of the object of the invention is because take following technical scheme, the wintering method of golden butterfish, comprises following concrete technical step:
(1) the fry time is thrown in: throw in fry selection of time in late June to early July, throw in fry 2.5-3 centimetre, throwing in density is 70-100 tail/cube water body, and fry grows to 7-9 centimetre and starts to sieve fish branch mailbox, through sieve fish branch mailbox, finally form density at 25-30 tail/cube water body;
(2) bait is fed: throw the seedling initial stage to by the end of July, to throw something and feed manufactured feed, starting August throws something and feeds is full fish slurry, with the 60-80% of conventional feeding volume throw something and feed fish slurry, feed in conjunction with conventional manufactured feed, controlling the growth rate of golden butterfish, making golden butterfish to maintaining during the 11-12 month between 450-500 gram, slow down its growth rate, build up resistance;
(3) build up resistance: in the breeding process of golden butterfish, especially at 1 monthly age, 2 monthly ages and 3 monthly ages, within every 10 days, mix bait respectively and to throw something and feed compound vitamin or polysaccharide 1-2 time, the 3-5% that multidimensional, polysaccharide press feed relative adds;
(4) net cage is arranged: at the ebb fluoran stream surface that rises of fish culture net cage, set up the abortive haul case with fish culture net cage same specification respectively, with abortive haul case dash stream, reduce flow velocity, making the activity of fish few, is not easily injured, sand hill is carried additionally, in order to fixed cage in the corner, bottom of fish culture net cage and abortive haul case;
(5) later stage feed: the early spring macrura reevesii survive the winter smoothly, water temperature progressively rises, when water temperature reaches 20 DEG C, throw something and feed every day containing feed 4-5 time of fish slurry, each feeding volume is the 20-30% of conventional feeding volume, refer to the feed adding fish slurry by the 1-2% of feed relative containing fish soluble feed, so feed and feed by normal feeding volume afterwards until adult fish listing for 10-15 days.
Take the present invention of above-mentioned measure, in the breeding process of golden butterfish, have employed the measure of the extra large vivo environment of breeding fish of multidimensional solution adjustment, in conjunction with the throwing seedling time, feed bait, the aggregate measures such as net cage setting and later stage nursing, improve the resistance of surviving the winter of golden butterfish, after taking above-mentioned measure, the overwintering mortality of golden butterfish is down to less than 2% by original more than 10%, the culture benefit of raising, make also there is fresh and alive golden butterfish listing dull season in the listing of golden butterfish, the cultivation added value of raising.
