Coilia mystus (L.) is a small fish of economic importance, belonging to the Family Engraulidae. It occurs abundantly along the coast of Amoy and vicinity. The present investigation was undertaken with the chief object of finding out the compostion of food and its seasonal variation. A total of 612 stomachs were examined; of these, only 22 stomachs were found to be empty. The following are the results of the investigation:(1) Coilia mystus feeds chiefly upon planktonic Crustacea, of which Copepoda is, by far, the most important, constituting no less than 75.9% of total food. Of the 15 species of Copepoda identified, Paracalanus pqrvus, Pseudodiaptomus marinus and Tortanus forcipata are relatively more important than the others. Among other Crustacea, the relative importance of various groups Is of the following order: Decapoda (including Lucifer and Brachyuran larvae) > Mysidae > Euphau-siacea > Amphipoda > Ostracoda > Cumacea > Stomatopoda. Next to Crustacea in the order of importance of food conic Chaetognatha and fish ova, the former being the more important of the two. Judging from the composition of food, Coilia mystus is a plankton-feeder.(2) The composition of food is more or less subject to seasonal variation. The order of numerical importance of various groups* in the four seasons is as follows: SPRING (Mar.-May): Copepoda > fish ova > Decapoda > Amphipoda > Mysidae> Euphausiacea > Cumacea> Stomatopoda, young fish. SUMMER (Junc-Aug.): Copcpoda> fish ova> Decapoda >Mysidae> Amphipoda> Euphausiacea > Cumacea > young fish.AUTUMN (Scpt.-Nov.): Copepoda > Decapoda > Mysidae > Ostracoda > Euphausiacea > Amphipoda > Stomatopoda > young fish.WINTER (Dec.-Feb.): Copepoda > Decapoda > Euphausiacea > Cumacea > fishova > Mysidae > Amphipoda > young fish > Stomatopoda. (3) The composition of food varies with age or length (from the tip of snout to the end of body, exclusive of caudal fin) of fish which appears to he related to the density of gill-rakers. The younger fishes (less than 15 cm. in length) with denser gill-rakers (2.0-2.7 rakers per 1 mm.) feed largely upon smaller crustaceans (Cope-poda); whilst the older fishes (over 15 cm. in length) with sparser gill-rakers (1.4 1.9 rakers per 1 mm.) feed largely upon larger crustaceans (Mysidae, Euphausiacea, Stomatopdda, Decapoda). It shows that increase in the size of fish is associated with increrase in the size of food animals eaten.(4) There exists a fairly close agreement between the composition of food and the composition of plankton in the surrounding waters. During the months of March and November when both fish and plankton were collected at the same time off Hai-Chen near Amoy, Copepoda was found to be the most dominant group in both food and plankton. It shows that the fish fed heavily upon those crustaceans occurring most abundantly in the plankton. In this respect, Coilia mystus exercises no selectivity of food. The writers are of the opinion that abundance and availability rather than selection by the fish determine the species of animal eaten.(5) A comparison of the food of Coilia mystus with that of other Clupeoids in Amoy waters reveals the predominance of Copepoda in the diet of most of these fishes. For the sake of increasing the yield of these economic fishes, it is essential to enhance the production of Copepoda in nature by artificial means such as to fertilize the water with nutrient salts, especially phosphates and nitrates, to increase the production of phytoplankton which will, in turn, lead to the higher production of Copepoda.

1.六丝鲚的食料差不多完全是浮游动物,以甲壳类为主,其中以桡足类为最重要、十足类(包括莹虾)次之,糠虾类,端足类,磷虾类更次之。除甲壳类以外,它还捕食很多毛头类和鱼卵,所以六丝鲚应属蜉食性的鱼类。 2.六丝鲚的食料成份有季节变化,不过不很显著:春夏两季以桡足类为主,鱼卵次之,十足类(包括短尾类幼虫)更次之。秋季以桡足类为主,十足类(包括莹虾和短尾类幼虫)次之,糠虾更次之。冬季以桡足类为主,十足类次之,磷虾类更次之。总的来看,桡足类在四季食料中都占了绝对优势。六丝的次要食料则随季节而异;春夏两季是鱼卵,秋冬两季都是十足类。值得注意的是:糠虾类和介壳类在秋季食料中的比率增加,磷虾类在冬季食料中占相当重要位置。食料的季节变化是和浮游生物的季节变化分不开的。 3.食料种类大小和体长有关:体长在15厘米以上的捕食较大的甲壳类(如磷虾类,口脚类和十足类等),而体长在15厘米以下的则捕食较小的甲壳类(如桡足类)。这和鳃耙密度有关:前者的鳃耙较稀(1毫米长中有1.4—1.9鳃耙)而后者的鳃耙较密(1毫米中有2.0—2.7鳃耙)。 4.食料和浮游生物存在着一定关系;在浮游生物中占优势的种类也同样地在食料中占优势。桡足类便是一个...

Miracil D is effective against Schistomia Mansoni,but is ineffective against SchistosomaJaponica.The present communication deals with the preparation of seventeen new compoundsof the hydrochlorides of 3-dialkylaminomethyl-thiochromanones including its 7-chloro-and 7-methoxy-derivatives,which are related to Miracil D in structure.Those compounds were prepared by means of the Mannich reaction from the correspondingthiochromanone,amine and paraformaldehyde.Besides the hydrochloride of the Mannich base,tar-like substance was also obtained as the by-product of the reaction.It was found that theaddition of few drops of alcoholic hydrochloride solution could prevent the formation of the tar-like substance and thus increase the yield of the hydrochloride of the Mannich base.All the products,especially the 7-chloro-derivatives,were unstable in aqueous solution onstanding for several hours; but they were stable even on boiling if a few drops of dilute hydro-chloric acid solution were added.The physical and chemical properties of the decompositionproduct in aqueous solution and those of the above mentioned tar-like substance were identicalfor the same thiochromanone.It was probably a dimer of the corresponding 3-methylene-thio-chromanone.

Field observations and laboratory studies revealed that the “white soil” in Tai Lakeregin was formed as a result of surface water-logging.The iron content of the wholesoil and the clay fraction in the “white horizon” at a depth of from about 25 cm to 40cm was rather low,and as a consequence the alumina/iron oxide ratio of the “WhiteHorizon” was high as compared with other horizons.The soil differed from the “de-graded paddy soil” of Japan in that it was not a result of present-time formation.The infertility...

Field observations and laboratory studies revealed that the “white soil” in Tai Lakeregin was formed as a result of surface water-logging.The iron content of the wholesoil and the clay fraction in the “white horizon” at a depth of from about 25 cm to 40cm was rather low,and as a consequence the alumina/iron oxide ratio of the “WhiteHorizon” was high as compared with other horizons.The soil differed from the “de-graded paddy soil” of Japan in that it was not a result of present-time formation.The infertility of the soil was found to be due chiefly to the lack of available nitro-gen and phosphorus,especially in the “white horizon”.Field experiment revealed thatthe application of large amount of manures and fertilizers could increase the yield of riceby about three times as compared with the control treatment.

根据研究结果,认为太湖地区的低产白土,曾经遭受过一定程度的表面潜育过程。但是白土层的出现,并不是现代水稻土成土过程的产物,而且这种白土的特性,又与太湖地区的一般脱沼泽土不同。这种白土的低产原因,是由于施肥过少,因而有效养分,特别是氮和磷比较缺乏所致。物理性质不良也可起有一定影响。由于有机质含量和胶体含量都较少,所以保蓄养分的能力也较差。通过田间试验证明,深耕结合施用大量有机肥料,可以变低产为高产,在一次改良措施后,水稻即可增产一倍以上。
