The snubnose pompano, Trachinotus blochii, is a euryhaline, pelagic, active swimming, marine tropical fish that is commonly found in the Indo-Pacific region, including the Red Sea (Froese & Pauly, 2020). This fish has been identified as a potential new species for aquaculture in Saudi Arabia, hence, baseline studies have been conducted on this species in order to determine its growth performance and production potential under the Red Sea conditions (i.e., salinity: 42 ppt). In the first experiment, baseline growth and FCR of the fish were studied by feeding the fish with locally available commercial feeds (40-46% crude protein; 9-17% crude lipid; 18-23 P/E ratio). Fish at an initial size of 209 g ABW were stocked at 6 kg ton-1 and were cultured for 80 days. The results showed that the fish attained 473-508 g after 80 days and gained around 99-113 g month_1 (Avg. temperature=27°C), with FCR values around 1.59-1.89 (Table 1). The commercial diet containing 40% crude protein and 17% lipid, P/E ratio=18, showed the best growth and FCR performance. Another experiment was also conducted to determine the effects of different Red Sea temperatures (24, 28, 32°C) on the survival and growth of the fish. The results showed that survival was not affected by the different temperatures, however, the weight gain was highest at 32°C (165 g month-1) but no significant difference with 28°C temperature (138 g month-1). At 24°C the weight gain (67g month-1) of the fish was significantly reduced by 59%. Feed intake was significantly higher at 32, followed by 28 and lowest feed intake at 24°C. FCR was significantly higher at 24°C, while 28 and 32°C showed no significant difference in their FCR value (Table 2). Based on our results and experimental conditions used, the predicted optimum temperature for growth of the fish is 32.9°C, while for FCR at 30°C. Lastly, we determined the digestibility of different protein source ingredients in the fish and used them to formulate practical diets for the snubnose pompano. The results of the digestibility experiment and the feeding experiment using the newly formulated diets will be presented at the conference. Based on our results, the snubnose pompano is considered a highly promising fish species for mariculture in the Red Sea.
