Fine scale fish is a kind of precious economic coldwater fish. In this report, we found the growth equation of this fish is: L_t=71.5 (1-e~((-0.1156)(t-0.0711)) and W_t=3235 (1-e~~((-0.1312)(t-0.0711))~3. The relationship between the length and weight of this fish is W=0.01776 L~(2·8369). The relationship between maximum day energy intake (DEImax) and weight is DEImax=0.024W~(1·2340) and the relationship between ecological growth efficiency () and weight is W=3.3114w~(-0.4278).

Fine scale fish is a kind of precious economic coldwater fish. In this report, we found the growth equation of this fish is: L_t=71.5 (1-e~((-0.1156)(t-0.0711)) and W_t=3235 (1-e~~((-0.1312)(t-0.0711))~3. The relationship between the length and weight of this fish is W=0.01776 L~(2·8369). The relationship between maximum day energy intake (DEImax) and weight is DEImax=0.024W~(1·2340) and the relationship between ecological growth efficiency () and weight is W=3.3114w~(-0.4278). The relationship between maintenance metabolism energy (MME) and weight is MME=0.03828w~(0.8443). The relationship between day energy growth (G) and day energy intake (DEI) can be described as G=a+bDEI.By analysing, we established the energy budget of fine Scale fish of 3 size groups in 7%, 5%, 2.5% and 1% feeding levels according to winberg formula C+G+ (F+U). The feeding level should not be lowwer than 5% in fish farming for fine scale fish.

本文报导了细鳟鱼(Braochymystax enok P.)体长与体重的关系、最大日摄入能与生长能的关系、生态生长效率等方面生长与能量代谢的研究结果。并确定养殖中最低投饵水平,对生产有一定的指导作用。

Feeding-growth experiments on rock fish (Sebastodes jusccsccns H-) were carriedout at 4.0-27.3C of seawater temperature during Dec., 1983-May, 1984 and Jun.,1990-Jan., 1991. The results were as follow:1. The mean daily food consumption (2.4-10.0g) and this consumption as aproportion of experiment fish body weight (l.1 %-4.4%) have remarkable monthlychanges and similar trends. The suitable feeding temperature of this fish is from8C to 25C and feeding intensity would be very low outside this range.2. The monthly...

Feeding-growth experiments on rock fish (Sebastodes jusccsccns H-) were carriedout at 4.0-27.3C of seawater temperature during Dec., 1983-May, 1984 and Jun.,1990-Jan., 1991. The results were as follow:1. The mean daily food consumption (2.4-10.0g) and this consumption as aproportion of experiment fish body weight (l.1 %-4.4%) have remarkable monthlychanges and similar trends. The suitable feeding temperature of this fish is from8C to 25C and feeding intensity would be very low outside this range.2. The monthly changes of rock fish ecological growth efficiency range from6.5 %-34.7 % (16.7 % in average).3. The mean daily increments of body weight in April, June, July and Octo-ber-December were higher than that of the other months and the peak months ofrock fish feeding and growth were October-December.

于1983年12月-1984年5月和1990年6月-1991年1月以中国科学院海样研究所生物培育楼养殖黑为材料,进行黑周年的摄食-生长实验,以探讨其生态生长效率变化规律。结果表明,作为冷温性鱼,黑在4.0-27.3℃水温条件下都有摄食;平均日摄含量为2.4-10.0g,相对体重的百分比为1.1%-4.4%.单见,这二者的周年变化趋势基本一致;平均体重日增长量以4,6,7月和10-12月份较高。生态生长效率波动于6.5%-34.7%范围内,年平均为16.7%。

The growth experiments of five fishes, common Japanese conger (Astroconger mgriaster), Bartail flathead (Pistycephalus indicus ), Black porgy (Sporus macrocephalus ), spotbelly rockfish (Sebastes pochycephalus) and banded dogfish (Triakis scyllium), were carried out. It was concluded that the ecological growth efficiency of these fishes, feeding Diopatra neapolitana, Loligo beka and so on, were between 3. 833. 6%, and 16. 0% in average. The mean relative daily food consumption fluctuated between 1. 6-11. 5%....

The growth experiments of five fishes, common Japanese conger (Astroconger mgriaster), Bartail flathead (Pistycephalus indicus ), Black porgy (Sporus macrocephalus ), spotbelly rockfish (Sebastes pochycephalus) and banded dogfish (Triakis scyllium), were carried out. It was concluded that the ecological growth efficiency of these fishes, feeding Diopatra neapolitana, Loligo beka and so on, were between 3. 833. 6%, and 16. 0% in average. The mean relative daily food consumption fluctuated between 1. 6-11. 5%. In addition,' food coefficients, mean daily food consumption and mean daily increment of body weight were discussed in this paper.

在常温下进行星鳗(Astrocongermyriaster)、       (Platycephalus indicus)、黑鳗 (Sparus macrocephalus)、厚头平(Sebastes pachycephalus)和皱唇鲨(Triakis scyllium) 等五种鱼类的生长实验,得出这5种鱼类摄食巢沙蚕、火枪乌贼、斑 (碎块)、带鱼 (碎块)和玉筋鱼的生态生长效率波动于3.8~33.6%范围内,平均为16.0%,相对 平均日摄食量处于1.6~11.5%之间,另外,对饵料系数、平均日摄食量及平均体 重日增长量进行了探讨。
