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。

This paper summarizes our practical experiences for years on the Ctenopharyn- godon idellus (Cuv.et Val.),Hypophthalmichthys molitrix (Cuv.et Val.) and Aristichthys nobilis (Rich.)spawning twice a year under strengthening cultivation conditions.After making a preliminary study on the morphological cytology and histology of the development of their ovaries,experiments show that immediately after the first spawning of these pond-cultured fishes the oocytes of the Ⅱ,Ⅲ and Ⅳ phase can be seen existing simultaneously,especially the early,middle and late stages of the Ⅲ phase can be distinguished clearly. Based on these observation we have come to the conclusion that the Ⅲ phase oocytes can develop into the Ⅳphase oocytes in the same year by strengthen- ing cultivation of the parent fishes.But if the fishes are cultivated in an ordinary way without further strengthening after spawning,the ovaries will degenerated to the Ⅱ phase.Thus the non-synchronous development of the oocytes in the ovaries of these fishes is the internal factor which accounts for the artificial spawning of these fishes more then twice a year.

本文总结了高州水库多年来在强化培育下家鱼一年两次产卵的生产实践经验,并从卵巢发育的细胞形态学和组织学进行了初步研究后指出:在这几类家鱼第一次刚产卵后的卵巢中可以观察到第Ⅱ、Ⅲ、Ⅳ时相卵母细胞同时并存,其中可以明显地见到处于早、中、晚期的第Ⅲ时相卵母细胞,它们在亲鱼强化培育下可以当年发育成第Ⅳ时相卵母细胞,如果对产后的亲鱼不进行强化培育,卵巢将退化至第Ⅱ期。家鱼卵巢中卵母细胞发育的非同步性,是获得一年多次产卵的内在因素。

Studies on the artificial inducement of reproduction in common eel (Anguilla japon-ica) have been carried out since 1973. The parents were collected from Tai Hu. They were induced by injection with pituitary gland of carp and HCG. The results of induce-ment show that the females can be induced to mature by means of injecting with smalldosage of the gonadotrophie hormones at an interval between 15--20 days each time and5--6 times in total. All the females were matured in 7--8 times, and the method seemsto be...

Studies on the artificial inducement of reproduction in common eel (Anguilla japon-ica) have been carried out since 1973. The parents were collected from Tai Hu. They were induced by injection with pituitary gland of carp and HCG. The results of induce-ment show that the females can be induced to mature by means of injecting with smalldosage of the gonadotrophie hormones at an interval between 15--20 days each time and5--6 times in total. All the females were matured in 7--8 times, and the method seemsto be of good effect. The spawning of common eel usually takes place in the early morning between 4:00and 6:20 A. M. at water temperature between 18.5--24.5C. The spawning place isjust under the surface of the sea water. Soon after spawning the females begin to takefood and gradualty restore to health. The remnant of ovary absorbs rapidly. Thesephenomena lead us to consider whether the gonad can redevelop and mature again. The 3--days old larvae demonstrated that the digestive organs are incompletelydeveloped, and the yolk sac is nearly absorbed. The intestine is filled with foods andwithin it there is a violent ciliary movement. This may be a kind of special method ofnutrition in transition. The larvae lived 19 days (434 hours).

本文报道了自1979年以来河鳗人工繁殖研究的基本情况,包括亲鳗催熟、催产以及胚胎发育和培育等试验内容。 试验结果表明,在人工催熟和水温逐渐升高的条件下,大部分亲鳗在4月上旬至5月中旬性腺成熟。从1974年至1978年总的产卵受精率为8.4%(其中流卵和产死卵者不计在内)。亲鳗自然产卵的时间一般在凌晨4时至6时20分之间,水温在18.5-24.5℃范围。产卵行为较特殊,产卵前发情时,雄鳗和雌鳗先后由池底阴暗处游至水表,沿池边环游追逐,最后在较小范围内急游产卵授精,产毕又回至池底。海水盐度在23-29.8‰范围,均能产卵受精,并孵出鳗苗。 孵出后头两天的仔鳗悬于水表;第3天的仔鳗,卵黄囊大部分吸收,消化道全通,在肠内开始发现食物团,肠道内有强烈的纤毛运动,鱼体开始悬于水中,有极缓慢的下沉和上升;第4天眼球出现黑色素,晶体透明,上、下颌能启闭,有四对牙齿;第5天,肠道有蠕动波,出现肝脏原基,静止时侧卧水底;第14天,仔鳗在微流水中能不断游动,在静水中常处于水底。仔鳗养至第19天,存活434小时。
