정치망과 들망에 의해 어획된 멸치를 축양하여 어분 크기, 어획방법, 이송방법등에 따른 생잔율의 차이를 조사하였다. 1. 중형 멸치 (전장 $7.8~9.6cm$, 분중 $3.6~4.8g$)를 $20~25$일간 축양한 생잔율이 $70-92\%$였음에 비하여, 소형 멸치 (전장 5.2cm, 분중 1.0g)는 어획후 12시간 동인의 생잔율이 $16\%$였다. 2. 어획된 멸치를 운반조에 수용하여 축양장까지 이송할 때, 운반조를 예인한 거리가 멀수록, 또 이송속력이 빠를수록 축양중의 생잔율이 낮다. 3, 정치망과 들망으로 어획된 멸치가 다 같이 상당히 좋은 생잔율을 보였으나, 이 두 어법 사이의 생잔율의 차이는 이 두 시험의 결과로는 단정할 수 없다.
Preliminary creel-holding test of live anchovies which are to be used as bait for the skipjact fishery, was conducted on the fish caught by set net and lift net. They were held in the creels constructed with bamboo frame and minnow netting, during the period of Oct. 24-Nov. 28 in 1972. If was found that the survival rate of the creel-held anchovies varied by the size of fish, the towed distance and speed of fish-carrying creel in which the fish were accomodated after catchi. 1. The survival rate of the medium size anchovies, 7.8-9.6cm in length and 4.6-4.8 g in weight, was $70-92\%$ during the holding period of 20-35 days. Whereas, only $16\%$ of juvenile anchovies, 5.3cm in length and 1.0 g in weight, were survived for 19 hours after catch. 2. During the time of transport, the farther and faster the creel containing fish were towed, the less fish were survived in the subsequent holding period. 3. Though both the set net and lift net could be fairly used to catch live anchovy, no decision between these two gears could be made in this experiment to determine the superiorness for the subsequent survival rate.
