| 内容記述 | In the culture of yellow-tail, Seriola quinqueradiala TEMMINCK et SCHLEGEL, sand eel, Ammodytes personatus GIRARD, anchovy, Engraulis japonica (HOUTTUYN), and jack mackerel, Trachurus japonicus (TEMMINCK et SCHLEGEL), are usually used as available diets and have been considered to have various merits for the fish culture. But these fresh fish diets are perishable and cause the dietary disease. In order to avoid such defect of the fresh food fishes, it may be desirable to accomplish the artificial diets as complete yellow-tail foods. As a preliminary study for the exploitation of artificial feed mixture, two artificial feed mixtures were tested against sand eel diet, one of which was a modified formulation of the Oregon pellet and the other was a reformed type of the Halver' s trout culture diet. The experiment was carried out during from August 11 to October 26 (1964) in the experimental small floating net (3 × 3 × 3m), set in the offshore of the laboratory located at Ono near Hiroshima. The water temperature, salinity and the other environmental conditions there varied with the season. The net was exchanged to keep the foulings away from it at times. The food supply was adjusted the amount to, in dry basis, equivalence of sand eel, which was restricted to 80 percent of sufficient feeding. The yellow-tails were fed twice or three times each day. Body length and weight of fish were measured weekly and according to these velues, feeding level for the following interval was adjusted. Results obtained are summarized as follows. 1) Three diets used in this experiment were the frozen sand eel, the mixed diet (fresh fish meat-meal mixture diet) and the synthetic diet (Tables 1, 2, 5). 2) There were differences in the rate of growth in weight and length (Figs. 1, 2). The sand eel diet was the most efficient, and the synthetic diet the worst. 3) The difference of fatness among three diets was also observed, and both the sand eel diet and the mixed diet were more efficient than the synthetic diel (Fig. 3) .4) It may be considered that there are some correlations between the fatness and the growth of gonad, therefore, the composition and the size of diet fed at each stage of fish condition must be sufficiently studied in the future. 5) On the relative growth of the body weight and liver weight (liver weight/body weight × 100), the fish fed with the sand eel diet gave higher value than that with the artificial diets (Fig. 6). On the contrary, in the case of pyloric caeca weight, the fish fed with synthetic diet showed the highest value (Fig. 8). 6) The observed conversions of food into flesh were most efficient after feeding the sand eel diet, followed in order by the mixed diet and the synthetic diet. 7) There were also differences in the protein required per kilogram of fish produced, and both the sand eel diet and the mixed diet were more efficient than the synthetic diet. 8) Chromic oxide was used as an indicator of the digestibility. Gross estimation of protein digestibility showed that the synthetic diet has considerably lower value than the sand eel and also the mixed diet. 9) None of these artificial diets may be considered as food suitable for raising the yellow-tail at this time. | |||||||||||

| 内容記述 | 1964年8月11日より10月26日までの間,3種の餌料を用いハマチの小割飼育試験を実施し,魚体成長,肥満度,内臓諸器官重量および餌料効率の点から考察して次のような結果を得た。1)使用した3種の餌料は,冷凍イカナゴ,混合餌料および人工配合餌料である。2)体重,体長からみた成長ではイカナゴ餌料区が最もよく、次いで混合餌料区,最も成長の悪いのは人工配合餌料区であった。3)3餌料区の中で最大の肥満度を示したのはイカナゴ餌料区であり,最小は人工配合餌料区であった。飼育期間中の週ごとの変化ではイカナゴ餌料区が最小であり,他の餌料区はかなり大きい。4)成長段階と肥満度との間には,なんらかの関係があると考えられ,今回の人工配合餌料がこのような関係に十分適合していたとは考えられず,今後成長段階に応じた餌料組成,形状などについて十分な研究が必要である。5)内臓諸器官重量については特に肝臓,幽門垂について考察し,飼育中体重と肝臓重量の相対成長ではイカナゴ餌料区が肝臓重量増が大きく、人工配合餌料区は小さい。幽門垂の場合は全くこの逆がみられた。6)餌料の増肉係数では乾物基準で人工配合餌料,混合餌料,イカナゴ餌料の順に小さくなり,この点でも人工配合餌料はよくなかった。7)蛋白効率の点でもイカナゴ餌料が最もよく,人工配合餌料が最も悪い結果を得た。8)蛋白消化率ではイカナゴ餌料,混合餌料はともに80%以上であるに対して,人工配合餌料は60%台の値を示し,今後改良すべき点を多く残している。 | |||||||||||
