Growth and Predator-Prey Interaction of Asian Seabass, Lates calcarifer and Sabaki Tilapia, Oreochromis spilurus in Polyculture System

This study estimated the survival, growth, fry production, and farming cost of Sabaki Tilapia Oreochromis spilurus broodstock in the following five outdoor production system types: arena, raceway, cage, concrete pond, and earth pond. The experiments were performed in triplicates in the year 2020 with 300 broodstocks per production system. Survival rate, growth performance, fry production, and farming cost were monitored. Our results indicated that Sabaki Tilapia fry production was feasible under high‐salinity conditions in the production system types studied; however, the systems showed significant differences in terms of survival rate, growth performance, and fry production. The arena and raceway systems were the most effective and exhibited the highest fry production.

“…The purpose of this study was to determine whether two common species used in such systems, namely Asian seabass (Chithambaran, 2019;Monwar, Ruhul, Sarker, & Das, 2013) and largemouth bass (McGinty, 1985;Ouizgane, Farid, Droussi, & Hasnaoui, 2017), are susceptible to francisellosis, a major disease of tilapia. The findings of this study advance our understanding of the pathogen's expansive host range and help to modify management and vaccination strategies in predation polyculture systems.…”

Francisella orientalis is a highly virulent, emerging bacterium that causes mass mortalities in tilapia. This pathogen also affects numerous other warm‐water fish species, including three‐line grunt, hybrid striped bass and various ornamental fish. This study sheds light on two new species of fish that are susceptible to F. orientalis. Asian seabass and largemouth bass showed variable levels of susceptibility in a bacterial challenge experiment. After intraperitoneally injected with a dose of 106 CFU/fish, a total of 64.28% and 21.42% mortalities were obtained in Asian seabass and largemouth bass, respectively. Meanwhile, Nile tilapia showed acute mortality of 100%. All fish showed typical lesions of francisellosis, including multifocal granulomas in the spleen and head kidney. Immunohistochemical analysis revealed strong positive signals inside the granulomas of all fish. The bacterial recovery in solid media from infected fish was highest in Nile tilapia (85.71%), followed by Asian seabass (35.71%) and largemouth bass (21.42%). PCR results tested 100% positive for Nile tilapia, and 78.57% and 21.42% for Asian seabass and largemouth bass, respectively. In conclusion, Asian seabass and largemouth bass are susceptible to this pathogen, which warrants new management strategies when employing predation polyculture systems of these species with tilapia.

“…Sabaki tilapia (Oreochromis spilurus) is the most popular and widely farmed marine tilapia species in the Kingdom. Its seed availability to farmers, fast growth rate, tolerance to a variety of cultural situations, appeal with customers, and ease of breeding in captivity are the factors contributing to its extensive culture (Chithambaran, 2019). Results of the experiment showed that use of probiotics such as Sanolife Pro W and Protexin Balance improved growth and survival of sabaki tilapia, O. spilurus.…”

The use of beneficial bacteria to improve fish health and growth is an innovative method in aquaculture practice. A study was conducted to test the efficiency of two commercial probiotics, such as Sanolife Pro-W and Protexin Balance on the microbial load in culture water and growth performance of Sabaki tilapia, Oreochromis spilurus in fiber glass tanks (400 liters) for a period of 75 days. Sanolife was supplied at 3ppm in the rearing water daily, and designated as Treatment 1. Protexin was incorporated at the rate of 1ppm in a supplementary feed, containing 35% protein in diet and considered as treatment 2. A control was also maintained without treating with probiotics in culture water or feed. Healthy and uniform size fish (3.1 ± 0.5g) were stocked at the rate of 25peaces/tank and both treatments and control tanks were set on a randomized design and triplicated. Water quality parameters (physical and chemical), microbial load in water, growth performance and body composition (nutrients) of fish were assessed during the culture period. Significant difference (p<0.01) on growth was observed between control and treatments, the highest growth was recorded in Protexin treated fish. Water quality parameters did not show significant variations. Carcass protein and lipid content showed significant difference between control and treatments. Considerable reduction in bacterial population and improved growth were observed in Sanolife Pro W treated water, when compared to Control. The result shows that Sanolife significantly reduce the bacterial population in culture water and Protexin improves the growth of fish. The outcome of the study has great application in the field of tilapia aquaculture sector in the Kingdom.
