Turbot is one of main mariculture kind of China.Its fast growth, easily domestication, acceptant mixed bait, suitable high-density breeding.But for the administrative skill of throwing something and feeding of turbot, the suitable feeding volume of system research turbot, the frequency of throwing something and feeding and time, yet there are no report both at home and abroad at present.
Summary of the invention:
The objective of the invention is to set up young turbot and culture the management method of reasonably throwing something and feeding, improve feed efficiency, reduce aquaculture cost, save China's feedstuff resource; Reduce fisheries environment and pollute, advance the sustainable sound development of culture fishery, for the turbot aquaculture management provides new scientific method.
The present invention finishes according to following method of operating:
Juvenile turbot culturing and feeding method: for the young turbot of specification at 25g-50g, every afternoon, the 15:00-18:00 point was thrown something and fed once.Feeding volume be satiated with food 80%, i.e. the 1.0%/d of young turbot body weight.
With the prior art contrast, the characteristics of the technology of the present invention are:
1. the feeding volume of young turbot, the frequency of throwing something and feeding and time have been carried out system research, from all angles such as growth performance, food utilization, immunologic function and cultivation water environment of young turbot, overall merit the influence of way to manage of throwing something and feeding to the turbot aquaculture.
2. 80% the level of throwing something and feeding of finding to be satiated with food does not influence the growth and the immune response of young turbot, and the close growth performance of throwing something and feeding can obtain and be satiated with food.
3. the suitable frequency of throwing something and feeding is 1 time/d, the turbot of throwing something and feeding once a day can reach with industrial aquaculture at present in the identical growth result of generally throwing something and feeding 3 to 4 times the every day of employing, use manpower and material resources sparingly.
4. 15:00 point-18:00 point was thrown something and fed and was thrown something and fed than other times section afternoon, can significantly promote the growth of young turbot, reduced by 20% feed cost, and it is nearly 100% that feed efficiency improves, and significantly improves productivity effect.

As can be seen from Table 1, along with the reduction of the level of throwing something and feeding, the whole opisthosoma of experiment fish weighs and rate of body weight gain shows downward trend.But 80%, 90% and 100% the young turbot of being satiated with food of throwing something and feeding, heavy and the whole last rate of body weight gain difference of whole opisthosoma is remarkable (p＞0.05) not, the 70% experiment fish rate of body weight gain of throwing something and feeding horizontal group significantly is lower than 100% horizontal group (p＜0.05) of throwing something and feeding, and 50% the throw something and feed experiment fish rate of body weight gain of horizontal group is minimum.The 60% heavy coefficient of variation of the whole opisthosoma of experiment fish of throwing something and feeding horizontal group significantly is lower than 80%, 90% and 100% horizontal group (p＜0.05) of throwing something and feeding, all the other each groups do not have significant difference (p＞0.05), the reduction of the level of throwing something and feeding can not bring the differentiation of young turbot individual growth, and the competition of ingesting of this fish is not fierce.The difference level of throwing something and feeding has appreciable impact to the feed efficiency of young turbot, decline along with the level of throwing something and feeding, the feed efficiency of experiment fish shows the trend of rising, and 50% and 60% the horizontal group experiment fish meal efficient of throwing something and feeding is significantly higher than 100% horizontal group (p＜0.05) of throwing something and feeding.
Table 2 has been listed the different influences of level to the young turbot immune indexes of throwing something and feeding.The difference level of throwing something and feeding has no significant effect (p＞0.05) to turbot serum lysozyme, superoxide dismutase and alkaline phosphatase.Reduction along with the level of throwing something and feeding, the turbot PAS shows the trend (p＜0.05) of reduction, 80% to the 100% group difference not significantly (p＞0.05) of throwing something and feeding, and the 70% and 50% group experiment fish serum phosphatase of throwing something and feeding significantly is lower than 100% group (p＜0.05) of throwing something and feeding.TAC shows the trend (p＜0.05) that raises and afterwards reduce earlier.
As can be seen from Table 3, the difference young turbot breeding environment water quality index of having thrown something and fed horizontal appreciable impact.Along with the reduction of the level of throwing something and feeding, the nitrite nitrogen in the cultivation water environment, ammonia nitrogen and phosphate all significantly reduce (p＜0.05).80% nitrite nitrogen of throwing something and feeding horizontal group significantly is lower than 100% horizontal group (p＜0.05) of throwing something and feeding, and does not have notable difference (p＞0.05) with 50% to 70% horizontal group of throwing something and feeding.50% to 70% throw something and feed horizontal group nitrite nitrogen and ammonia-nitrogen content all significantly is lower than 90% and 100% horizontal group (p＜0.05) of throwing something and feeding.50% and the 60% horizontal group phosphate content of throwing something and feeding significantly is lower than 70% to 100% horizontal group (p＜0.05) of throwing something and feeding, and it is not remarkable that other respectively organizes difference.
In sum, 80% (1.0%/d that is equivalent to body weight) of the level of being satiated with food of throwing something and feeding can reach and close growth result of the level of being satiated with food and the higher feed efficiency of throwing something and feeding, and reduces feed cost, significantly reduces nitrite nitrogen and ammonia nitrogen content in the cultivation water environment.
2. the suitable frequency of throwing something and feeding is definite: set 3 groups of different frequencies of throwing something and feeding, throw something and feed every day 1 time (8:00), 2 (8:00; 17:00) with 3 (8:00; 12:00; 17:00), young turbot (average weight 29g) is carried out 45 days growth experiment by a definite date, write down the feeding volume of every day, each frequency of throwing something and feeding is established three repetitions.The experimental session water temperature is 14-15 ℃.When growth experiment finishes, long situation of determination experiment sashimi (raw fish) and food utilization, the result is as shown in table 4.
Table 4 difference is thrown something and fed, and frequency is grown to young turbot and the influence of food utilization
