Abstract:
Physiological response studies were made on commercially important crabs, Portunus pelagicus sampled from Bangsaen Chonburi, Thailand. In the present work, physiological effects of enhanced temperature (20 ํC, 25 ํC, 30 ํC), salinities (25%SW-125%SW) and concentration of copper (0,0.75, 1.5, 3, 6 ppm) on the crabs were studied in laboratory experiments. Both weight specific oxygen consumption and heart rate of crabs increased with increasing temperature and decreasing salinity. When transferred to decreasing salinity in the laboratory, the crabs showed a pronounced decrease in osmotic, ionic and blood ammonia-N concentration but the crabs showed a pronounced increase in ammonia-N excretion rate. Exposure to copper might result in breakdown of osmotic-ionic regulation, increased oxygen consumption and heart rate which might be followed by increasing ammonia excretion rate. The highest copper concentration induced disruption which occurred at lower salinities. Changes in the environment (temperature, salinity, cooper concentration) have a significant effect on the physiological respones (weight specific oxygen consumption, heart rate, osmotic and ionic regulation and ammonia-N excretion rate) except in blood ammonia-N concentration, which no significant difference (P<=0.05) was detected.
