Recirculating aquaculture systems (RASs) for fish culture have been used for decades. The RAS has the advantages of using small land areas and minimal water volume for intensive production. Although RAS has proven to be very efficient, it still has some challenges. One of such challenges is sometimes poor water quality (high levels of ammonia nitrogen and nitrite nitrogen) which mainly emanates from accumulated fish waste and uneaten feed. Probiotics have been adopted by many fish farmers as an alternative to control microbial infections compared to antibiotics, as it improves water quality, enhances the fish immune system and improves fish growth. Although some studies have been conducted on the effectiveness of probiotics in ponds or still-water setups in lab conditions, little study has been done for its effects on improving water quality and fish growth in the RAS.
To investigate the effectiveness of probiotics in promoting fish growth and water quality, a 60-day experiment was carried out in a RAS on blackhead seabream, Acanthopagrus schlegelii using commercially available probiotics. The experiment was conducted in four identical RASs and each system consisted of three rearing tanks (70 L each) with a set of water treatment system. Fifty fingerlings (34±0.20 g, 5.95±0.25 cm) were stocked in each tank. Probiotics were applied to fish feed in ... 전체 초록 보기
