Principles of Fish Nutrition

Aquacultural production is a major industry in many countries, and it will continue to grow as the demand for "sheries products increases and the supply from natural sources decreases. As in more traditional forms of animal production, nutrition plays a critical role in intensive aquaculture because it in#uences not only production costs but also "sh growth, health and waste production (Gatlin,...

Physiology and Endocrinology: Nutrition, Growth and Stress

ratios of insulin to glucagon (I/G) from 14E to 17E ranged from 1.8 to 2.2 which were significantly greater than normal I/G ratio in the postabsorptive state in avian species (1.2-1.7). The results indicate that insulin is an important promoter of chick embryo growth by anabolic drive to promote protein deposition especially during the embryonic rapid growth period. There also was a significant...

Physiology and nutrition of Lampropedia hyalina.

A detailed study of the physiology and nutrition of Lampropedia hyalina revealed that it is an aerobic, cytochrome-containing chemoheterotroph which is limited in its energy sources to a few intermediates (and close derivatives) of the Krebs cycle. Reducing compounds at low levels are potent growth inhibitors. The microbe has no photosynthetic ability (despite its previous taxonomic position wi...

History of nutrition and acid-base physiology.

In the 17th century the notion of nutrition and diet changed in northern European countries. First chemical experiments fostered the idea that salts resulted from a union of acids and bases. Digestion was no more regarded as a process of cooking but a succession of fermentations controlled by a balanced production of acids and alkali. Life seemed to depend on the equilibrium of acids and alkali...
