Conclusions It is emphasized that this report is based on one year's work only and therefore the effect of particular diets and of heavy, medium, or light feeding through two or more years cannot be taken into consideration. However, from these experiments and until more information is available, certain tentative conclusions as to the feeding of brood stock seem Justified. Those judged of more immediate practical interest are given first. 1. Underfeeding through eight months preceding spawning is not harmful to the quality (fertility-viability; of eggs. 2. Although good eggs were obtained from heavily fed yearlings and, using a high meat diet and high meat and fish diet, very good eggs from 2-year-olds, it appears that overfeeding older fish (3-year-olds) a good 60–40 diet definitely reduces the average quality of eggs. 3. Starting with a very low level, not taking into consideration the subsequent condition of the brood stock, and in so far as the cost of eggs is based on the cost of food, increased fee...
