Abstract

Probiotics are defined as live microorganisms which when administered in adequate amounts, confer a health benefit on the host. Nowadays, Probiotics are used for eco-friendly and sustainable production in many production areas. They have also been common organisms that used in aquaculture as growth promoter, stress tolerance, pathogen inhibition, and nutrient digestibility, to increase water quality. Probiotics use in aquaculture comprehensively reviewed as an alternative to antibiotic treatment. However, very few studies have addressed the effects of probiotics on reproductive performance and gamete quality of fish. Thus, this review summarizes most current studies on the effects of probiotics on reproductive performance and gamete quality in fish and evaluates further applications of probiotics in reproduction of fish.
