The Effects Of Acute Stress On Rainbow Trout (Oncorhynchus Mykiss), Ayşegül Kubi̇lay, Gülşen Uluköy
Turkish Journal of Zoology
The physiological effects of acute stressors (transport, handling, netting and confinement) on rainbow trout in an aquaculture system were investigated. Serum cortisol level, serum glucose and lysozyme activity were determined in rainbow trout stressed by acute stressors, and compared with those of unstressed (control) fish. Serum cortisol, glucose levels and lysozyme activity were significantly higher(P

This experiment was conducted between 15th February 2000 (day 1) and 31st January 2001 (day 350) at the DSI-Gölköy Fish Production Station, Bolu (Turkey). Abant trout larvae obtained from eggs of wild Abant trout broodstocks in Lake Abant and rainbow trout larvae obtained from eggs of the hatchery broodstocks in Gölköy Fish Production Station were used. Trials I and II involved eight groups (four Abant and rainbow trout experimental groups, and four Abant and rainbow trout parallel groups). A total of 1784 larvae was used in both the trials. At the end of the experiment, although the mean wet weight …
Histological Study In The Digestive Tract On Larval Development Of Rainbow Trout ( Oncorhynchus Mykiss, Walbaum, 1792), Mustafa Sarieyyüpoğlu, Aydin Gi̇rgi̇n, Si̇bel Şi̇mşek

In this study the development of the digestive tract of newly hatched rainbow trout ( Oncorhynchus mykiss) larvae were examined. The digestive tract was attached to the anus a few hours after hatching. On the second day their mouths were open and the differentiation in the esophagus started. Mucosal folds contained a large quantity of cubic epithelium and goblet cells. Goblet cells were stained positively with Alcian blue and also stained negatively with P.A.S. The wall of the esophagus consisted of a circular muscle layer and a thin tunica serosa. It was possible to see a thin longitudinal muscle layer …
