研究了不同海洋贝类的滤水率及温度对滤水率的影响。1)蛤类种群的滤水率用下列公式估算的滤水率（F，l · m-2 · h-1）与北海道滨中湾的沙查林拟蛤和东京湾板津潮滩的菲律宾蛤仔进行了比较：F= fn· RT · RS ·Pn其中fn为Ln mm的蛤的滤水率RT为田间温度T（°C）下fn的校正系数，RS为田间盐度S（psu）下fn的校正系数，Pn ; m-2，沙打旺15个大小级、沙打旺7个大小级的蛤密度（个. philippinarum ; m，大小级数。利用从每个研究地点收集的文蛤，研究了滤水率以及个体大小、温度和盐度对滤水率的影响。通过对日本东京湾的调查，分析了滨中湾温度、盐度和文蛤密度的月变化。2）比较了日本滨中湾、日本滨中湾和日本东京湾4种双壳类的个体滤水率。philippinarum、贻贝Mytilus galloprovincialis和佩尔纳Perna viridis。3)本文研究了温度对中国蛤蜊、文蛤、文蛤、白蛤、白蛤、蛤仔、蛤仔主要结果如下：1）2龄群体对滤水率的贡献以沙田螺（65%）和厚壳贻贝（65%）为主;菲律宾（58-78%）。3龄、4龄、1龄和5龄以上的沙田柚分别占19%、8%、5%和3%，3龄以上的沙田柚分别占14%~ 22%和8%~ 20%。菲律宾的对高山云杉来说，优势年级的不规则出现可能是影响其过滤的主要因素。1 · h ~（-1））的变化规律如下：M. galloprovincialis（2.5），R. 3）对沙田原（P. sachalinensis）、菲律宾原（M. philippinarum）、沙田原（M. sachalinensis）和绿色原（P. viridis）的最适过滤温度为20 ℃; lamarcki和M. lusoria，M. chinensis，R. philippinarum和M. galloprovincialis为27.5°C; coruscus和P. viridis的温度分别为32.5°C。
The filtration rate and thermal effects on the rate were evaluated in various marine bivalves. 1) The filtration rates by a clam population (F, l · m-2 · h-1) estimated using the following equation were compared with Pseudocardium sachalinensis in Hamanaka Bay, Hokkaido and Ruditapes philippinarum in Banzu tidal flat, Tokyo Bay.F=Σmn=1fn · RT · RS · Pnwhere ; fn, filtration rate of a clam with Ln mm (mean shell length of divided size class) examined under the experimental conditions ; RT, correction coefficient for fn at field temperature T (°C) ; RS, correction coefficient for fn at field salinity S (psu), Pn ; clam density (no. · m-2) of 15 size classes in P. sachalinensis and 7 size classes in R. philippinarum ; m, number of size classes. Filtration rate and effects of body size, temperature and salinity on the filtration rate were examined using the clam collected from each study sites. Monthly changes of temperature, salinity and clam density were investigated in Hamanaka Bay, and were evaluated from analysis of available data in Tokyo Bay, 2) The individual filtration rate corrected for body size and temperature was compared between 4 bivalve species, P. sachalinensis, R. philippinarum, Mytilus galloprovincialis, and Perna viridis. 3) Thermal effects on the filtration rate were examined in 8 bivalve species, including Mactra chinensis, Meretrix lamarcki, M. lusoria, and Mytilus coruscus.Following are major findings ; 1) The contribution of the 2 year-old population to the eatimated filtration rate was dominant in P. sachalinensis (65%) and R. philippinarum (58-78%). Following contributions were for the 3 (19%), 4 (8%), 1 (5%), and over 5 year-old (3%) in P. sachalinensis and over 3 (14-22%), and 1 year-old (8-20%) in R. philippinarum. In the case of P. sachalinensis, a irregular occurrence of dominant year class may be major factor affecting on the filtration.2) The estimated filtration rates (l · indiv.-1 · h-1) of 30mm individual at 15°C were as follows : M. galloprovincialis (2.5), R. philippinarum (1.5), P. sachalinensis (1.3), and P. viridis (0.64).3) The temperature considered to be optimum for filtration was 20°C for P. sachalinensis, M. lamarcki and M. lusoria, 25°C for M. chinensis, R. philippinarum and M. galloprovincialis, 27.5°C for M. coruscus, and 32.5°C for P. viridis.
