Although much attention has been paid to the fishes accompanying floating algae in the daytime, so far as is known, no study has been made of those at night. This paper is concerned with the relation between the life of fishes and the floating algae during night as well as day.
The authors obtained larvae. and juveniles of fishes accompanying the floating algae at night as well as in the daytime. They also collected fishes under a 1-kilowatt lamp at night, independent of algae. Collections were made during April, 1958 to March, 1959, in the vicinity of Tsuyazaki, Fukuoka Prefecture, by mean of a rectangular scoop net and dip nets. The results are given in Table 1. In the case of day collections, the floating algae drifting near the rectangular route as shown in Fig. 1 were scooped up. In the case of night collections, the authors left port thirty minutes before official sunset, and slowly proceeding searched for the floating algae with the help of lamp. The lamp was held at the bow, light-ing the water surface within about thirty meters. At certain locations the boat stopped with the lamp hung on the side of the boat for collecting about an hour.
Species and size ranges of fishes obtained from the floating algae at night were similar to those obtained in the daytime. In Oplegnathus fasciatus and Dasson trossulus from the night collecting the characteristic yellow coloration of their bodies was not revealed, and the blackish patterns on whitish ground color were clearly seen. Aluterid fishes did not show any noticeable color change. Most of the species collected under the mere lamp light were different from those accompanying the floating algae. In the few species caught both under the mere lamp and under the algae, differences in size and color patterns were observed. The majority of the juveniles appeared under the lamp light were those living near the surface, and some species among them were also obtained with the floating algae. This fact can be understood that those grown juveniles only temporarily used floating algae as their habitat in place of the algal zone in shallow waters where they were to live after the change of habitat in their life history.
Number of individuals as well as of species in the collections varied in seasons. Fish were abundant during spring to early autumn and scarce in winter. The largest number of species, 17, was obtained in early August, and the least number of species, 3, in October and in early February. Sebastes spp. were found in abundance from mid-April to mid-May. Late May yielded large catch according primarily to the abundance of Seriola quinqueradiata and Girella punctata in the collection. Dasson trossulus and aluterid fishes were taken in abun-dance during July to December. The largest number of individuals was collected in early September, represented by but 6 species. Girella punctata and Agrammus agrammus dominated from February to early March, but total number of individuals was rather few.

The fishing efficiency to the solar radiation energy was calculated in the Yellow and the East China Seas from 1954 to 1960.
The obtained values ranged between 0.000216 and 0.000256% which is almost equal to that in Georges Bank by CLARK, G. L. and about a half that in Tokyo Bay by HANAOKA, T.
The deficiency of the detailed data about Chinese catch by species made this calculation somewhat difficult and only rough estimation.

　看護職の疲労の実態と疲労改善ケアへのニーズを明らかにすることを目的に、青森県内のA病院に勤務する看護職を対象に質問紙調査を行った。

　274名に配布し、233の回答を得た（回収率85.0％）。蓄積的疲労兆候インデックスによる女性全体の疲労は、8特性全てにおいて、基本平均訴え率より高くなっていた。残業時間、子供の有無、職種、診療科の違いにより疲労に差が認められ、その影響は、個人的要因、勤務に関する要因が考えられ、疲労には特徴があることが明らかとなった。特に疲れる仕事内容は【直接的な処置・ケア】【スタッフ間のコミュニケーション】等があり、心身疲労への対処法は、【趣味・娯楽】【他とのふれあい】等であった。148名（68.2％）がリラクゼーションケアの習得を希望しており、疲労の特徴により希望するケアに違いがあった。

　看護職の疲労を改善していくためには、対象の疲労の特徴を把握し、適した疲労改善ケアを行っていく必要性が示唆された。
