| Juveniles of the white shrimp Litopenaeus vannamei were kept Without food for between 0 to 15 clays to evaluate the impact of starvation oil physiologic state (oxygen consumption, poststarvation refeeding, index, nitrogen excretion, and O:N ratio) and digestive enzymes activity. Physiologic changes were found after 6 days of fasting, and refeeding ability declined as a result. Nevertheless. the shrimp were able to Survive 16 days Without food. Starvation Caused metabolism to drop progressively toward a basal level (21 J (.) h(-1 .) g(-1)) and a decrease in the rate of ammonia excretion, because of the catabolism of amino acids front soluble protein in the hepatopancreas. This decrease led to an increase in digestive enzymes specific activity (U/mg... |
