Plagiognathops microlepis Bleeker,an economic freshwater fish (Xenocyprininae,Cyprinidae) widely distributed in China,is a favorite with our broad masses,but itsnatural population is not large and the yield of this fish is low in many waters.As a result of our experimentation and research,now we can successfully conductartificial propagation and culture of this fish on a large scale.We have already stoc-ked a reservoir with a large number of its sizable fingerlings,in anticipation of inc-reasing yield in the coming years.For pond-farming,it has been demonstrated that the participation of Plagiog-nathops in polyculture with the team of“domestic”carps does not interfere with thenormal growth of the latter,and the total yield of a pond is actually increased byabout 10%.The fish is easy to catch (by seining);this makes it a desirable objectfor the practice of recurrent stocking and“skimming”within a year in ponds in-tended for bumper yield.The juveniles as well as the adults of Plagiognathops feed on humus,bottomdetritus and benthic algae,which are not much utilized by the traditional“domestic”fishes.Growth rate of Plagiognathops is rather high during the first two years of life:young fish 6 months of age weigh about 100—150 g,those of 18 months old,above250 g (450 g for the largest specimen);the average weight of 2-year-old individuals is500 g,a size ready for the market.Owing to its tastiness and relatively more edibleparts,fish even of the grade of 100—150 g are readily acceptable to customers.The principal results of our experiments on the rearing of this fish,togetherwith the relevant biological data obtained,are given in this paper.

细鳞斜颌鲴是在我国分布较广而又为群众所喜爱的一种野生经济鱼类。这种鱼在某些天然水体中可成为优势种群,产量较大,最高可以占总渔获量的50%以上。但有许多水体中却没有这种鱼或数量不大。通过试验和研究,我们已能对这种鱼进行大规模的人工繁殖和苗种培育,近年来,已将数万尾大规格鱼种投放到一原来只投放“家鱼”(泛指鲩、青、鲢、鳙,以下均同)的水库中,并将检验其增产效果。实践证明斜颌鲴在池塘中与现有“家鱼”混养时,非但不影响“家鱼”的生长,并可使池塘总产量增加10%以上;原因是这种鱼主要以其他养殖鱼类尚未利用或未能充分利用的腐屑、腐泥和着生藻类为食物。该鱼头两年生长较快,两周年可达一市斤左右,并第一次达到性成熟,这种规格的鱼上市就是经济价值高的优良食用鱼。因其在池塘中易于捕捞,故也是丰产塘中轮捕轮放的好对象。按普通“家鱼”种的培育方法当年鱼可养成4寸左右,第二年底都能在半斤以上,大的可达8两半。由于该鱼头小肉多而味美,故即使2—3两重的鱼在市场上也受到顾客的欢迎。本文还介绍了养殖这种鱼的方法及其有关的生物学资料,并讨论了在天然水体中促使这种鱼增产的可能途径。

1 . Round scad (juvenile and adult) appears phototatic on the horizontal phofogradient from 10-1-10lux illumination. With the increasing of light intensity no rainsing of phototaxis was shown.2 . On the non-homogenous photogradient caused by the obvious contrast between light and dark formed by vertical light source, the swimming time of Round scad under weak illuminafion region is longer and shorter under stronger illumination region. The ratio between them is 1:4.3 . The phototaxis of jurenile of Round scad is stronger than that of adult.4. When water temperature is 24.5-27℃. optimum illumination of Common Japanese mackerel (juvenile) is within the amplitude between 0.01 and 71ux.5 . In both single and group experiments, the results of photoresponse of Common Japanese mackerel are the same and the response of group experiment is even more stable.6 . As the comparison of phototaxis between the 5 marine fishes, Round scad (juvenile and adult) and Common Janpanesc mackerel (juvenile) all belong fo the positive photoresponse, but not to the stronger type. Among them, the phototaxis of Round scad (juvenile and adult) is stronger than that of Common Japanese mackerel (juvenile).

1.在水平光梯度内兰圆鲹(幼鱼、成鱼)自10~(-1)—10~3lux的照度区内都表现出趋光性,但随光强的增加未出现趋光性加强的趋势。 2.在因垂直照明而形成的明暗对比显著而非均匀性的光梯度内,兰圆鲹在弱照度区游动时间长,在强照度区游动时间短,其游动时间的比例为1:4。 3.兰圆鲹幼鱼的趋光性比成鱼强。 4.在水温为24.5—27℃时,鲐鱼(幼鱼)的适宜照度区为0.01—71ux范围内。 5.无论个体或群体实验,鲐鱼对光反应结果一致,而且群体反应更稳定。 6.对于五种海水鱼趋光性之比较看,兰圆鲹(幼鱼、成鱼)和鲐鱼(幼鱼)都属于对光有正反应,但不属于趋最强光的一种类型,其中兰圆鲹(幼鱼、成鱼)之趋光性比始鱼(幼鱼)强。

1.

1. The food organisms of young mackerel of the year were diverse in species and they included polychaeta, Chaetognatha (Sagitta crassa), Copepoda, Amphipoda (young Themisto gracilipes), Caprellidea, Cephalopoda (Idiosepius paradoxa), fishes (young anchovy, Engraulis japonicus, young mugil, etc.), but fishes, cephalopods and crustaceans were the major varieties. Young mackerel of the year also ate seaweeds and other kinds of plant seeds, sand and mud. 2. In the Yantai-Weihai coastal region, young mackerel of the year, less than 89 mm FL in size, fed mainly on planktonic organisms. When they reached to the size larger than 80 mm, they could take various specieses of food organisms, showing their omnivorous feeding habits. There was a little change in food items taken by mackerel from year to year. In the Qingdao coastal region young mackerel of the year fed mainly on Idiosepius paradoxa, juveniles of Themisto gracilipes and juveniles of fish, but some groups fed among the dense clusters of seaweeds, consequently, in their stomach Caprellidea, seahorse, thread of hemp, etc. could be found. 3. As the FL of young mackerel of the year become longer, a slight change in their preference of food items could be observed, though it was not conspicuous. This was due to the feeding habits of the young fish of 35 mm FL was nearly similar to that of the adult and in the shallow coastal waters planktonic organisms were scarce but young anchovies (Engraulis japonicus) and mugils and Idiosepius paradoxa, etc. were in abundance. 4. Young mackerel of the year fed day and night. At night they followed the tide and came into the shallow coastal waters where they snatched juveniles of anchovy and Themisto gracilipes throughout the whole night and daring the daytime they fed on planktonic organisms, benthos, young fishes, seaweeds and other kinds of plant, seeds, etc.. 5. Since the adult mackerel fed mainly on adults of anchovy (Engraulis japonicus) and Themisto gracilipes, young mackerel of the year fed mainly on the juveniles of anchovy and Themisto gracilipes. There was a close relation in nutrition between mackerel and anchovy ane Themisto gracilipes. Adult mackerel lived in the coastal waters deeper than 20 meters, where they searched their food organisms, while young mackerel of the year lived in the coastal waters shallow than 20 meters, where they might grew up and took these areas as their nursery grounds.

1.当年生鲐鱼幼鱼摄食种类十分广泛,包括多毛类、毛颚类的强壮箭虫、桡足类、端足类的细长脚(虫戎)幼体、钩虾、麦杆虫,头足类的微鳍乌贼,鱼类的鳀鱼幼鱼、梭鱼幼鱼等,其中以鱼类、头足类、甲壳类为主;并吞食海藻碎片、植物碎屑、种子、砂泥等,有杂食性的表现。 2.烟威沿岸海区叉长35—194毫米当年生鲐鱼幼鱼以微鳍乌贼、细长脚(虫戎)幼体、鯷鱼幼体等为主要食物。叉长80毫米以下个体主要以浮游生物为食,80毫米以上个体摄食种类广泛,有杂食性表现。频年摄食种类变化不大。青岛沿岸当年生鲐鱼幼鱼也以微鳍乌贼、细长脚(虫戎)幼体、鱼类幼鱼等为主要食物,但有部分群体在海藻丛中摄食,所以在胃中出现麦杆虫、海马、麻绳丝等。 3.随着体长增长有食物转化现象,但不很显著。原因:一为当年生鲐鱼幼鱼叉长35毫米即近似成鱼的摄食习性,一为沿岸浅水浮游生物较贫乏,鲐鱼、梭鱼等幼鱼和微鳍乌贼等较多。 4.当年生鲐鱼幼鱼昼夜均进行摄食,夜间各个时间随着潮流游到沿岸浅水攫食鯷鱼幼鱼和细长脚(虫戎)幼体。白天摄食浮游生物、底栖生物、鱼类幼鱼以及海藻碎片、植物碎屑、种子等。 5.鲐鱼的成鱼以鯷鱼和细长脚(虫戎)为主要食物,当年生鲐鱼幼鱼也以鯷鱼幼鱼和细长...
