“…Cd exposure seriously damages the reproductive system of fish. When exposed to Cd for a long time, the cellular structure and function of ovarian tissue or sperm tissue is significantly damaged, causing the reproductive ability of fish to reduce, the development of hatched embryos to be incomplete, and the growth and development of juvenile fish to be significantly retarded ( Figure 1 ) [ 97 , 98 ]. Cd not only destroys the structural and functional integrity of fish gonads, but also affects the reproductive regulation system of fish by affecting the expression and secretion of hormones [ 99 , 100 ].…”

Large amounts of enriched cadmium (Cd) in the environment seriously threatens the healthy and sustainable development of the aquaculture industry and greatly restricts the development of the food processing industry. Studying the distribution and toxic effects of Cd in fish, as well as the possible toxic effects of Cd on the human body, is very significant. A large number of studies have shown that the accumulation and distribution of Cd in fish are biologically specific, cause tissue differences, and seriously damage the integrity of tissue structure and function, the antioxidant defense system, the reproductive regulation system, and the immune system. The physiological, biochemical, enzyme, molecular, and gene expression levels change with different concentrations and times of Cd exposure, and these changes are closely related to the target sites of Cd action and tissues in fish. Therefore, the toxic effects of Cd on fish occur with multiple tissues, systems, and levels.

“…Clarias gariepinus exposed to at 6.1, 12.2, 24.4 ppm lead for 96 hr lead reduced sperm motility (Alkahemal et al, 2011). ppm copper reduced motility rate of spermatoazoids, reduced fertilization and hatching rate (Pinto et al, 2020). Furthermore, Danio rerio exposed to 20 and 40 ppb copper for 130 days hampered gonad maturation (Cao et al, 2019) (Table 1).…”

“…Exposure to Cd also resulted in the loss of motility and velocities (Marquez et al, 2019) in Prochilodus magdalenae spermatozoa. Exposure of Colossoma macropomum at 0, 0.6, 1.2 and 1.8 ppm cadmium concentration decreased motility rate of spermatoazoids and also fertilization and hatching rate were found to be decreased (Pinto et al, 2020). Cadmium exposure at 2.5 pm and 25 ppm for 27.3 seconds duration decreased sperm motility and velocity in Prochilodus magdalenae (Marquez et al, 2019;Browne et al, 2015).…”

Heavy metals are ubiquitous and deleterious contaminant present in the aquatic ecosystem. Their concentration has increased magnificently due to anthropogenic wastes, geochemical composition, farming and mining activities. Fishes are susceptible to heavy metal contamination and fishes live in aquatic environment which made them inevitable exposure to heavy metal. The excess release of contaminants into aquatic ecosystem has forced the fish to accumulate more heavy metal in their tissues. However, fishes reproduce in natural ecosystem which might have contaminated with heavy metal. Fish reproduction is the key process for fish recruitment in natural ecosystem and inevitable for aquaculture production. Water quality in terms of heavy metal contamination has a definite impact on fish reproduction. Hence, it is important to know the consequence of heavy metals on aquatic ecosystem and their effect on fish reproduction. Several reviews and reports are available that deals with the effect of heavy metals on fish health, blood biochemical changes and histological changes, cellular and physiological stress in vital organs but few comprehensive reports on toxic effect of heavy metals on fish reproduction are available. Heavy metals are reported to cause reproductive disruption in fish, inhibiting induction of vitellogenin, delaying oogenesis, enhancing luteinizing hormone secretion, declining parameters of gonadal somatic index and ovulation in fish. Therefore, this review paper presents a holistic details on the toxic effects of heavy metal on fish reproduction with special reference to male and female reproductive system.

“…In aquaculture, fertilization, embryo development and progeny performance are the candidate measures in broodstock management that are most likely to be affected by the environmental conditions in which sperm-oocyte communication takes place and fertilization occurs. 32,33 Several studies have demonstrated that the spermatozoa competitive capacity significantly influences fertilization success and offspring fitness. [34][35][36] These studies suggest that a multitude of internal and external factors, such as environmental pollutants, diet, cryopreservation, temperature, salinity and oxidative stress.…”

The biology of fish sperm, an important topic in the research of reproduction and fisheries from basic science to evolutionary and applied aspects, has implications for aquaculture management, fish breeding and biological conservation. The quality of spermatozoa plays a vital role in fish fertility, and directly affects the health and performance of offspring. Environmental factors that affect determinants of spermatozoa quality usually reflected in the DNA methylation pattern of the spermatozoa epigenome, which may change offspring's performance. The aim of the present study was to conduct a review on existing data about DNA methylation in fish spermatozoa as a biological tool for identifying the quality of offspring based on their phenotypes and performances. Furthermore, this study provides valuable knowledge from fundamental to applied sciences dealing with enhancement of breeding selection, fish reproduction and environmental adaptation. The review also describes the individual
