Resumo: | Four batches of 7 500 larvae were reared during a period of one month in 150 l tanks at 18° C. The first one was fed on the basis of estimates of the required daily amount of organisms that were made by one of the authors ; the second batch was fed on the average , of the estimates made by both authors ; the third and the fourth batches were fed, respecti­vely, with,20 % above and 20 % below this average. The densities of food in the tanks varied from 0 to 16 organisms /ml before the daily meal and from 1 to 25 organisms/ml after it. There was no significant difference in the final weight or length of the larvae, although the larvae receiving. the highest food level showed a significantly better growth at the age of 15 days. Survival seemed to be better at lower feeding levels. The food conversion rates varied from 34.1 to 15.3 (wet weight) and from 18.7 to 8.4 (dry weight). The best rates were obtained at the lowest feeding level.
