“…In all animals, spermatozoa quality parameters (e.g., motility, velocity and concentration) are determinants of male fertility, and are directly associated with fertilization, hatching and malformation rates. 229 Environmental factors affect spermatozoa quality during the period of testicular development and after discharge of sperm into the aquatic environment at spawning. 28,129,133,181 Our current knowledge indicates a relationship between spermatozoa quality parameters and changes of the DNA methylation pattern.…”

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

“…Nevertheless, the eggs must also control the alkalinization of the cytosol to avoid shifts far beyond necessary levels for metabolism activation because alkaline-dependent apoptosis has been proposed to occur in mouse ganglion neurons, opposed to the common acidosis-dependent origin suggested for apoptosis [112]. The Cl´-HCO 3´e xchangers are also likely to be involved in pH i regulation as they are found in direct relation to the activation of sperm motility [168,169]. The function of these exchangers is based on the driving force of Cl´gradients across membranes for the extrusion of HCO 3´a nd it is self-controlled by acidification of the cytosol: in acidic surroundings this activity sharply decreases by about 80%-90% [86].…”

Ocean Acidification (OA) represents a major field of research and increased efforts are being made to elucidate its repercussions on biota. Species survival is ensured by successful reproduction, which may be threatened under detrimental environmental conditions, such as OA acting in synergy with other climate change related stressors. Achieving successful gametogenesis, fertilization, and the development of larvae into healthy juveniles and adults is crucial for the perpetuation of species and, thus, ecosystems' functionality. The considerable vulnerability of the abovementioned developmental stages to the adverse conditions that future OA may impose has been shown in many species, including sea urchins which are commonly used due to the feasibility of their maintenance in captivity and the great amount of gametes that a mature adult is able to produce. In the present review, the latest knowledge about the impact of OA on various stages of the life cycle of sea urchins is summarized with remarks on the possible impact of other stressors. The cellular physiology of the gametes before, at fertilization and, at early development, is extensively described with a focus on the complex enzymatic machinery and the intracellular pH (pH i ) and Ca 2+ homeostasis for their vulnerability when facing adverse conditions such as acidification, temperature variations, or hypoxia.
