The feeding habit,age and growth,and the propagation of the mud carp,Cir-rhinus molitorella,has been studied.And suggestions concerning its culture have beenmade accordingly.The mud carp feeds mainly on phytoplankton.When water temperature is bet-ween 16.4℃ and 29.4℃,the fish have a strong appetite,above and below this tem-perature feeding declines.Most fish cease to eat at a dissoved oxygen level of 0.24—0.65 mg/l,and when the oxygen level exceeds 0.99 mg/l the feeding of the mudcarp becomes quite active.The age of the fish was determined according to the disposition of the circuli ofthe scales.New circuli are formed between March and November,which denote thegrowing period of the fish.Among the fish examined,the largest female had a body-length of 595 mm,wei-ghing 4,100 g,10 years of age;the largest male's body-length was 580 mm,weighing3,850 g,9 years of age.The correlation between body-length and body-weight is calculated for 261 fishfrom Yu-kiang River and for 382 pond-reared fish.Pearl-organs appear on the head and pectoral fins of the mature male duringApril through July.The females have none.The sex ratio of the 1,119 fish examined was about 1∶1.But when the fish weredivided into different size-groups,it was found that the proportion of the maledecreased as the size increased.The seasonal changes of the ovaries and the testes of the pond-reared mud carpwere studied.And the gonadal development of the pond-reared mud carp was com-pared with that of the mud carp caught from Yu-kiang River.It is found that the mud carp is capable of natural spawning in the Da-wang-tan Reservoir.During the years of 1962—1964,the spawning grounds of the mud carp inYu-kiang River were investigated.The ecological conditions for spawning include:water level rises rapidly (0.37—2.12m within 24 hours),the velocity of currentincreases markedly,and the water temperature ranges between 25.9 and 29.6℃.The minimum size for sexually mature individuals are as follows:fish from Yu-kiang River,female 273 mm,525 g,male 275 mm,415 g;pond reared fish,female247 mm,366 g,male 235 mm,291g.According to the data obtained from 28 fish,the fecundity for river fish is 84 eggs/g body-weight,and 139 eggs/g body-weight for pond reared fish.The embryonic development is divided into 4 stages and 26 periods while thepost-embryonic development,8 stages.Induced spawning has been successfully carried out from early-May until mid-June,with the water temperature from 22℃ to 29℃.Spawning takes place 4.5 to6 hours after the injection of pituitaries or gonadotropins.According to the experiences of the fish-farmers,in ponds for poly-culture ofvarious fish,a stocking rate of 1,000 fingerlings of the mud carp to each mou(666m~2) is suitable,the number of the silver carp (Hypophthalmichthys molitrix)fingerlings stocked should be kept at one-third that of the mud carp.In pondswhere the mud carp is intended to be the main object,a rate of 1,500—2,000 permou is desirable.

本文对鲮鱼的食性、年龄、生长和繁殖进行了研究,并对渔业生产提出了建议。鲮鱼以浮游植物为主要食料。在水温14.6—29.4℃时食欲旺盛。当水中溶氧量0.24—0.65毫克/升时,绝大部分个体停止摄食,而溶氧量在0.99毫克/升以上时,摄食强度很大。见到的最大个体:雌鱼体长595毫米,体重4,100克,10龄;雄鱼体长580毫米,体重3,850克,9龄。鲮鱼能在大王滩水库中自然繁殖。鲮鱼人工繁殖季节以5月初至6月中旬较适宜;催产时水温以22—29℃为好,注射催产剂的效应时间一般为4.5—6小时。见到的性成熟最小个体:郁江鲮鱼雌体长273毫米,体重525克,雄体长275毫米,体重415克;池养鲮鱼雌体长247毫米,体重366克,雄体长235毫米,体重291克。根据群众经验,一般池塘中鲮鱼每亩放养1,000尾,鲮与鲢的放养比例以3∶1较好,以鲮鱼为主体的池塘则每亩放养1,500—2,000尾较好。

A synthetic analogue of LRH(p-Glu-His.Trp.Ser·Tyr·D-Ala·Leu·Arg· Pro·NH·C_2H_5)used as a stimulant for spawning in “domestic fishes” produces a highdegree of spawning,fertilization and hatching for normal fry,and is popular withpisciculture farms.This paper reports further studies on the following aspects:stabilization of thestimulatory action of LRH-A,augmentation of its effectiveness and shortening of thetime for induction of spawning.Emphasis is placed on the responsiveness of silver carp(Hypophthalmichthys molitrix)to the LRH analogue,resistance to HCG upon repeatedtreatment with the hormone for periods covering many years,and the combinedeffect on spawning of cyclic AMP given at the same time with LRH-A.The mechanismof these effects is also discussed.

人工合成的LRH 类似物(焦谷·组·色·丝·酪·D-丙·亮·精·脯乙基酰胺)对家鱼催情产卵具有催产率高、受精率高、孵化率高的优点,深受广大水产养殖场的欢迎。本文进一步报导在稳定和缩短效应时间、提高催产率等方面的工作,重点研究了鲢鱼对LRH 类似物的敏感性,多年以HCG 催产的“抗药性”,水温变化对效应时间的影响及cAMP-LRH 类似物混合剂的催产效果,并就有关问题进行了讨论。

On the basis of species discrepancies of responsiveness to LRH--A, serum gonado-tropin (sGTH) levels of the mature female carps and immature female silver carpwere compared after cardiac injections of LRH-A at two different timos of a day.Fish sera were sampled at intervals either within 1 hour or during a 24--hour period.The sGTH concentration was measured by radioimmunoassay. In all cases, dealingwith the mature fish held under 18--20℃ two distinguished peaks were observed,one within 5 minutes and the other...

On the basis of species discrepancies of responsiveness to LRH--A, serum gonado-tropin (sGTH) levels of the mature female carps and immature female silver carpwere compared after cardiac injections of LRH-A at two different timos of a day.Fish sera were sampled at intervals either within 1 hour or during a 24--hour period.The sGTH concentration was measured by radioimmunoassay. In all cases, dealingwith the mature fish held under 18--20℃ two distinguished peaks were observed,one within 5 minutes and the other 5--6 hours later. The second peak was notdetectable in immature fish. This may signify that the second surge of GTH was moreimportant than the first in inducing spawning. When carp was subjected to lowertemperatures (11-13.5℃), the occurrence of the peaks was much delayed, which is inaccordance with the fact that when water temperature drops down beyond optimum,the response to the analogue is prolonged or even suppressed as has been found in farmpractice. When silver carps receiving LRH-A 23 days after the first ovulation which wasinduced by the same hormone analogue, the sGTH pattern was similar but higher in magnitude. Anatomical examination showed that ovaries had significantly proceededto the IV stage of maturation. though the GSI values were lower than that prior to thefirst ovulation. The long-term effect of LRH--A in terms of acceleration of ovarianrecrudescence in the postspawning phase of the reproductive cycle was apparent.

多年使用LRH-A催产的经验说明,不同鱼类对LRH-A的敏感性不同。为探索催产条件的规律,我们曾测定池塘中能自然产卵的鲤和不能自然产卵的草鱼、鲢产卵季节血清促性晚激素(sGTH)的日周期变化。本文则观察和比较心脏灌注LRH-A后1小时和24小时之内sGTH的变化。 三种鱼在灌注LRH-A后5分钟和5—6小时出现sGTH高峰,说明LRH-A对GTH的释放有立即的和迟缓的二种作用。不成熟的鲢也有“5分钟”的高峰,但未见5—6小时的峰。以LRH-A催产后23天的鲢对灌注LRH-A尤为敏感,能刺激sGTH的大量释放。经解剖这些鱼卵巢已发育到Ⅳ。是否在适当时间、温度进行当年第二次催产是值得试验和可能对生产有重要意义的课题。 水温急剧下降的情况下灌注LRH-A,sGTH的高峰出现推迟,可以解释LRH-A催产效应时间增长的原因。
