“…When the second experiment began, sticklebacks were already at 16°C and were exposed to a progressive increase in temperature from day 0 (the beginning of experiment 1). Under a low rate of water temperature increase (0.04°C h -1 ) corresponding to the increase applied in the present study, amylolytic activity levels in goldfish, carp, roach and perch juveniles seem to be at the same levels in all seasons [ 48 ]. The temporal decrease of amylase activity levels in our three temperature groups could be explained by the production of new isoenzymes with low-energy activation, which are more efficient even at low concentrations.…”

Determining digestive enzyme activity is of potential interest to obtain and understand valuable information about fish digestive physiology, since digestion is an elementary process of fish metabolism. We described for the first time (i) three digestive enzymes: amylase, trypsin and intestinal alkaline phosphatase (IAP), and (ii) three gut morphometric parameters: relative gut length (RGL), relative gut mass (RGM) and Zihler’s index (ZI) in threespine stickleback (Gasterosteus aculeatus), and we studied the effect of temperature and body size on these parameters. When mimicking seasonal variation in temperature, body size had no effect on digestive enzyme activity. The highest levels of amylase and trypsin activity were observed at 18°C, while the highest IAP activity was recorded at 20°C. When sticklebacks were exposed to three constant temperatures (16, 18 and 21°C), a temporal effect correlated to fish growth was observed with inverse evolution patterns between amylase activity and the activities of trypsin and IAP. Temperature (in both experiments) had no effect on morphometric parameters. However, a temporal variation was recorded for both RGM (in the second experiment) and ZI (in both experiments), and the later was correlated to fish body mass.

“…), barramundi ( Lates calcarifer ), Atlantic cod, turbot, tilapia and Japanese yellowtail (included in Tacon & Metian, ). Indeed, the lower FCR found for greater amberjack held at 26°C could be related to a higher protease activity and subsequently better protein digestibility (Abbink et al., ; Kofuji, Akimoto, Hosokawa & Masumoto, ), as digestive enzymes activity is directly related to temperature (Bowyer et al., ; Golovanova, Golovanov, Smirnov & Pavlov, ). A better protein retention for rainbow trout held at higher temperatures as been related to an improvement of the diet digestibility (Oliva‐Teles & Rodrigues, ).…”

Effect of temperature on growth performance of greater amberjack (SERIOLA DUMERILIRisso 1810) Juveniles

In order to successfully diversify Mediterranean aquaculture, it is necessary to determine optimum culture conditions of potential candidate species such as greater amberjack (Seriola dumerili). Among culture conditions, rearing temperature is a key factor for achieving optimum growth and maintaining fish welfare. However, little is known about the optimum culture conditions of greater amberjack (Seriola dumerili).Thus, the aim of this study was to determine the effect of three different rearing temperatures (17, 22 and 26°C) during 120 days on growth performance, body morphometry, biochemical composition, gut transit and liver morphology of greater amberjack (Seriola dumerili) juveniles. After 120 days of rearing, fish raised at 26°C showed higher (p < .05) body weight and specific growth rate than fish held at lower temperatures, as well as improved feed utilization, protein efficiency and nutrient retention percentages. Fish stomach emptying was faster (p < .05) in fish raised at 26°C than in fish held at 22°C and 17°C. Similar results were obtained for gut transit time, being gut emptying faster (p < .05) in fish reared at 26°C than in fish cultured at lower temperatures. Rearing temperature also induced changes in fish morphology which resulted in a higher (p < .05) caudal propulsion efficiency index for fish reared at 26°C. Based on these results, we conclude that greater amberjack fingerlings perform better at 26°C than at 22°C or 17°C.

“…At higher temperatures, the GET became shorter as there was an increase in fish digestive enzyme activity [ 35 , 36 ]. This finding also complements the assertion made by Suja et al [ 37 ], whereby rapid digestion rate coincides with FCE.…”

The present study was carried out to analyse the effect of water temperature on two components: (1) growth performance, and (2) gastric emptying time (GET) of African catfish Clarias gariepinus fingerlings. After 70 days, it was observed that experimental temperatures had no significant effects on the growth performance parameters, except for food conversion ratio (FCR) and food conversion efficiency (FCE). GET observation through X-radiography denoted that the shortest GET (10 h) was observed in fish reared at 32 °C and the longest GET (16 h) was observed in fish reared at 26 °C. The rapid digestion rate coincides with the FCR and FCE obtained in this study. Considering the limited scope of our study, more extensive studies on the impact of water temperature on other fish physiological parameters should be pursued. A better understanding of this research topic would be beneficial for the growth of African catfish fingerling aquaculture.
