Marine fish tank system and method for facilitating the breeding and spawning of marine fish

Abstract

The present invention relates to a marine fish tank system and method for facilitating the breeding and spawning of marine fish species. The system includes two fish tanks for housing broodstock (BF, BF1), with mechanisms for circulating water between the tanks (1000, 1010), collecting eggs (1003A), and maintaining optimal water quality. The system components include an egg collection net cum physical filtration net (1003A), coral rubble (1002) for biological filtration and calcium release, discharge pipes for waste removal, and a backwash pipe (1016) for cleaning the system. The system is further designed to aerate the water, monitor water levels (1001, 1001A), and enable non-intrusive observation of the broodstock. The method involves maintaining environmental conditions suitable for spawning, including water quality and aeration, and performing various operational steps to ensure efficient breeding and egg collection. The system’s operation promotes sustainability and natural behaviours in the breeding process, improving efficiency and egg quality. Figure 1
