Description
Technical field
The present invention relates to culture fishery technology and aquatic product matched field of feed, more specifically relate to and a kind ofly limit the aquatic fish cultural method of eating/being satiated with food and alternately throwing something and feeding.
Background technology
Occurring in nature is due to seasonal law, environment drastic change or the unequal reason of bio distribution, and wild fish ubiquity periodically lacks the phenomenon of food or poor nutritional.Adapt to as the one in Physiological Ecology, wild fish can by reducing the nutriment of analytic metabolism level and the storage of consumption autologous tissue, developed the even hungry suffertibility of coercing of inanition from aspects such as physiology, biochemistry and behaviors, if after this fully ingest, then normal physiological function may be recovered, also compensation phenomenon may be there is in growth, namely by reduce the basic maintenance level of survival needs, increase energy utilization efficiency or by improving grazing rate, the growth indexes such as make body weight, body long forereaches the population level of always fully ingesting.This fish because lacking food or poor nutritional recover the certain quick growth showed normally at food, be called as the compensatory growth (compensatorygrowth) of fish.
The compensatory growth of fish is generally divided into following 4 classes from the angle of compensation rate (body weight):
1) over-compensatory growth refers to refeeding a period of time again after hunger after a while or limit food, and weight gain has exceeded the weight gain continuing in same time to throw something and feed.
2) after full remuneration growth refers to hunger or limit food restoration ecosystem weight gain close to or reach the level of the group that continues to throw something and feed.
3) partly (limited) compensates and refers to energy normal growth in the restoration ecosystem of fish after hungry or limit are eaten, even growth rate is accelerated in a short time to some extent, but body weight finally can not catch up with fed continuous group, this phenomenon is more general in fish, as cod (Joblingetal., 1994), arctic charr (Miglavsetal, 1989), Hybrid tilapia (Wangetal.., 2000).
4) compensatory growth can not refer to that fish is when restoration ecosystem, not only body weight is unable to catch up with continuing fish of throwing something and feeding, and growth rate is also not as good as normal level.It is generally acknowledged and occur that this situation is because hunger or limit are eaten too serious, certain injury is caused to the physiological situation of fish, so that cannot normal level be returned to, if (1985) such as Schwarz are to the research of carp.
The factor affecting compensatory growth mainly comprises the kind, temperature, salinity, illumination etc. of limit food degree, restoration ecosystem time, the nutritive quality of food, sexual maturity degree, fish.
Research shows, the compensatory growth of different aquiculture animal shows different compensation features, even same biology also has the difference showing compensation at different vegetative stages.Limit food degree contains limit drinking water gentle limit food duration two aspects.Growth rate in compensatory growth process returns to normal level after showing as a period of time of first rising again.If the restoration ecosystem time is too short, growth rate not yet returns to normal level, just can not give full play to Compensation growth effect.Otherwise restoration ecosystem overlong time, Compensation growth effect is covered to a certain extent.Growth rate is all higher than the individuality continuing to be satiated with food recovering on a full stomach after hungry or limit food for aquatic livestock, but this growth rate not remains on higher level always, but declines gradually after a period of time and then return to normal level.
Although existing research shows likely to utilize compensatory growth principle to improve fish culture technology, hybridization sunfish (Robert is made as adopted alternately strategy that is hungry and refeeding, 1997) body weight gain increases, but in breeding production, accelerates fish growth speed according to compensatory growth principle and the example reducing aquaculture cost yet there are no all reports.
Sturgeon due to food ration larger, the bait feeding amount of juvenile fish is about 5% of fish body weight, throw something and feed every day 6 ~ 8 (Feng Guangpeng etc., 2004), so large daily ration, feeding quantity is a white elephant concerning breeding water body, may cause a large amount of residual of bait in reality cultivation, not only cause the waste of feed, the increase of aquaculture cost, the aggravation of water pollution is in addition for the threat causing again its existence concerning the sturgeon that water quality has higher requirements.Therefore, need to set up a good pattern of throwing something and feeding, improve the utilization ratio of feed, reduce residual bait and fish body excretion.Research shows, sturgeon has compensatory growth phenomenon, and its compensatory growth is ingested by raising and feed efficiency realizes (Huang Ying etc., 2010) jointly.For this reason, we consider to utilize this physiological phenomenon of the compensatory growth of fish to solve this problem, reducing the discharge of residual bait, improving condition of water quality, reducing environmental pollution and the object reducing aquaculture cost to reaching.
Summary of the invention
The object of the invention is to utilize compensatory growth principle, there is provided a kind of and limit the aquatic fish cultural method of eating/being satiated with food and alternately throwing something and feeding, the method can improve the utilization ratio of aquatic fish to feed, the nitrogen phosphorus discharge reducing bait waste and caused by residual bait, reduce environmental pollution, reduce aquaculture cost.
