This report concerns the aquatic and semiaquatic Hemiptera collected in Sri Lanka by Prof. Starmühlner and Prof. Costa during November and December 1970. A surprising number of new species have been found in the Starmühlner-Costa material, even in groups for which comprehensive revisions exist. Seven new species are described here.

Oil sardine blood tests against human typing sera indicated A-positive, A-negative and B-negative. The blood of mackerel is antigenically negative both for A and B. Electrophoretic studies on serum proteins revealed the existence of genetica1ly different groups of oil sardine and mackerel on the south-west coast of India.

A study was conducted at Banate Bay, Iloilo, from November 1975 to March 1976. Trials were conducted using spat collectors of four types, but no Modiolus metcalfei spat settled on any of the experimental collectors during the entire study period. Instead they attached to the exposed posterior half of the living Modiolus collected for reproductive cycle studies. The aquaculture potential of the brown mussel is considered to be low. Improvement of its production potential should be approached along the line of resource management rather than aquaculture. This management should be aimed at two objectives: (1) maintenance of enough adults on settlement surfaces, and (2) provision of space to allow new recruitments to grow. A possible solution, therefore, is controlled harvesting or thinning after the peak in the settlement season. In this manner, the chances of the mussel bed recovering year after year may be enhanced.

<正> 丹江口水利枢纽是长江流域中规模较大的水利工程之一。它的兴建导致了汉江的水文要素、鱼类饵料生物和鱼类资源的一系列变化。因此,研究丹江口水利枢纽建成后所引起的生态学效应,对于探讨三峡水利枢纽对长江鱼类资源可能产生的影响,制定三峡水库渔业规划具有一定的参考价值。此项研究工作于1976~1978年进行,调查范围包括丹江口大坝以下的整个汉江中下
