- 摘要：The present paper deals principally with a detailed comparative analysis of the length-weight relationship in 10 spawning shoals of the Large Yellow Croaker during their spawning season. The concept of length-weight relationship for species and the method of computation of length-weight standard regression for species are also discussed. The data used for the present paper were obtained from samples collected primarily for the purpose of studying its population structure and fecundity. These samples were collected in the years 1958-1960 from the main spawning grounds of the Large Yellow Croaker during its spawning periods.

The first part describes in detail the important morphological characters of the eggs, larvae and young fish of Engraulis japonicus Temminck and Schlegel. Description is based mainly on life organisms. The eggs used for observation were obtained from ]iaozhou Bay, Qingdao, with a plankton net during the spawning seasons in the years 1963 and 1964. The larvae hatched from these eggs were reared successfully in our laboratory to complete metamorphosis. Rearing continued for 76 days, and the largest one of young fishs reached a total length .of 60 mm. The second part deals with the abundance and distribution of the eggs and larvae in Bohai Sea and Yellow Sea. The area of investigation covered was west of longitude 124°E and north of latitude 34°N. Samples were monthly collections made in 1959, by vertical tows with the plankton net having a mouth diameter of 80 cm, The duration of the spawning season .of the anchovy, Engraulis japonicus is very long, lasting for about 6 months. Spawning,. which begins in May, takes place first in coastal waters of less than 30 meters in depth, later, gradually shifting to deeper offshore areas. The surface water temperature of the spawning ground ranges between 13°C and 28°C, and salinity 29一33%. The spawning area is extensive. Except where the salinity of the water was lower than 29% and the transparency of the water was very poor，eggs and larvae occurred in most parts of the areas surveyed.

They are most abundant in the 1ndo-West-Pacific region. The carangid fishes of China are well represented by 4 subfamilies, 166 genera and 70 species. The subfamily Caranginae is best represented, having 10 genera and 50 species, all of which are found in the South China Sea, 7 genera and 16 species range to the East China Sea, and 6 genera and 10 species to the Huanghai Sea. SecondIy, it is the subfamily Chorineminae which has 1 genus and 10 species, all occurring in the South China Sea. In the third place, the subfamily Seriolinae is represented by 4 genera and 6 species, all occurring in the South China Sea, 3 genera and 5 species in the East China Sea, only 1 genus and 3 species in the Huanghai Sea. The representation of the subfamily Trachinotinae is very weak， with only 1 genus and 4 species, all inhabiting in the South China Sea, and only a single species ranging to the East China Sea and Huanghai Sea. According to the thermal adaptation of the species, the Chinese carangid fishes may be grouped into 2 types, viz., the warm-water and the warm-temperate species. The warm-water species are abundant, having 58 species (83% of the total); the warm-temperate species are rather few, with only 12 species (17%). According to the geographical range of the species, the Chinese carangid fishes may be referred to 4 types: (1) the circumtropical-subtropical type, with 15 species (21% of the total); (2) the Indo-West-Pacific type, with 38 species (54%); (3) theWest-Pacific type, with 9 species (13 % ); (4) the endemic type, with 8 species (12 % ). Due to the relative prevalence and seasonal variation of the warm currents, the number of species found along the coastal waters of China decreases with the increase in latitude. Among the 70 species of China, aI1 are found in the South China Sea, 22 in the East China Sea (31%) , and 14 in the Huanghai Sea (20%). The fauna of carangid fishes of China is closely related to that of the neighbouring couutries. There are 50 species commonly distributed in China and 1ndonesia, 48 species in China and Japan, 45 species in China and Philippines and 18 species in China and Korea. There are 2 species confined in distribution to both China and Japan, 3 species confined in distribution to China, Korea, Japan and USSR. There are 8 endemic species in China, 10 in Indonesia, 3 in Philippines, 6 in Japan, and none in Korea.关键词：GEOGRAPHICAL DISTRIBUTION;THE CARANGID FISHES

发布时间：2023-04-28 - 摘要：Jiaozhou Bay is situated at the south side of the Shandong peninsula, between long. 120°5'30"-120°24'30"E and lat. 35°58'30"-36°14'20"N. It is about 29 kilometers wide and about 33 kilometers long, with a total area of about 255 square kilometers. Its water temperature at surface is rather varied, the February monthly mean is about 2℃, while that for August is about 25℃. The salinity of sea water varies monthly, the highest average monthly salinity being 31.24‰ in June and the lowest being 29.61‰ in August. The types of tides are regular semi-diurnal, with a tidal range of not over 4.7 m usually. The universal intertidal zonation by Lewis was used for Jiaozhou Bay, in which the belt from upper limit of Littorina to upper limit of barnacles is called littoral fringe, whereas that from upper limit of barnacles to upper limit of Laminaria is called eulittoral. In order to see how far the subjectively recognized zones represent an overall organism structure, we carried out a hierarchic distance analysis. The analysis was an example of a divisive shortest distance classification and information theory, in which frequency and cover data for individual species were used as the basis for both classification and amount of information. From the species pair association matrices, we constructed a hierarchical dendrogram to indicate the occurrence of some major subgroups.关键词：MARINE ALGAE;Jiaozhou Bay

The southern limit of its geographical distribution along the China coast is Jiaozhou Bay where it is commonly found only on harbour wharves or on ships. Since 1958, the Institute of Oceanology. Academia Sinica and the Qingdao Mariculture Station repeatedly transplanted seed mussels collected from Yantai (Shandong Province) and Dalian (Liaoning Province) to Qingdao for experiment culture, but failed finally in their efforts to propagate them. Owing to the mass culture that was constant1y expanding in 1975 and 1976, the use of waste ropes discarded after the harvesting of Laminaria as spat collectors was widely popularized in Jiaonan County, as a result of which there was a great increase in the amount of spats collected. Investigations showed that during 1974-1976, the amount of spats collected from the various culture grounds annually increased many times, even to tens of times (Tab. 2) From Tab. 3 it can be seen that by 1975， the number of spats collected amounted to 400 million, and by 1976 to 2900 million.关键词：MUSSEL;Jiaozhou Bay

发布时间：2023-04-28 - 摘要：Pectinidae is a rather large family of marine Pelecypod mollusk. Owing to the deliciousness of its adductor muscles (the dry products called "gan bei" in China) , this group of mollusk as the marine products is well known in the wor1d today. In our country the biology of two common edible scallops, Chlamys (Azumapecten) farreri and Chlamys (Mimachlamys) nobilis were studied in detail on the reproduction, growth, as well as the artificial breeding and cultivation. But up to the present time, the reports of Pectinid species and their distributions along our coast are still rare. The present paper dealing with 3 species which belongs to the subfamily Amusiinae is the second part of the studies of Pectinidae along China coasts. The samples of these species were collected by the Institute of Oceanology, Academia Sinica after liberation. Among the 3 species identified, Amusium pleuronectes pleuronectes is found more abundant in the South China Sea and in the rather deep water 16-85 m down. Amusium japonicum formosum is a rare species on1y found in the rather deep water off the coast of eastern part of Guangdong Province and Taiwan Province. Amusium japonicum balloti is also a rare species main1y found in Beibu Gulf in the depth from 10 to 40 m and it is recorded for the first time from Chinese waters.关键词：PECTINIDAE;AMUSIINAE

发布时间：2023-04-28 - 摘要：On the basis of laboratory investigation, 9 types of Al-basic sacrificial anodes with different compositions are selected and studied in the harbour. Anodic closed circuit potential and output currents are also measured. Anodic surface resolved characteristics are recorded in detail at the end of experiment. Current efficiencies and discharge capacities of anodes are calculated. Environment factors: temperature，conductivity, pH and salinity of sea water are measured too. It can be seen from the results that (1) properties of No. 1 anode are the best, next come Nos. 2,4,6,3,5,7,8,9 in that order. Nos. 1-6 anodes may be applied to protect marine constructions as anodic materials in marine engineering and their discharge capacities are 2-3 times as large as Mg-basic and Zn-basic anodes; (2) effect of alloy element In (indium) on anodic properties is evident, content of In being controlled at about 0.024%. If content of In exceeds 0.03%, properties of anode deteriorate; (3) output currents are affected by anodic properties themself, also by temperature and conductivity of sea water. When temperature and conductivity come down, anodic output current decreaes.关键词：AL-BASIC SACRIFICIAL ANODES;PROPERTIES

发布时间：2023-04-28 - 摘要：A Series of aerial remote sensing experiments were conducted from May 16 to 19, 1980 by Academia Sinica in the Bohai Bay to monitor pollution effect, the first one being made on May 16, 1980. Sea water spectral radiances were measured by a 101 W spectral radiance meter aboard a Meeg~8 helicopter, sea truth measurements and sampling were made from four boats. These sea truth measurements include suspended sediments, chlorophyll concentrations, water color and other water quality parameters. Stepwise Regression Analysis; was, used to determine regression equations relating the sea truth measurements (include suspended sediments and chlorophyll a concentrations and water color etc.) to sea water reflectances. Spectral reflectance data at 760 nm were used for countirig suspended sediments; for chlorophyll a, data at 480 nm, 620nm, .740 nm were used; for watet color data at 740 nm were used. The correlation coefficierits (measutenient of relative change between remotely sensed data and sea truth measurements) were about 0.7.关键词：DATA ANALYSIS;SPECTRAL SIGNATURES
