TL;DR: The recent ecotoxicological issue of pharmaceutically active compounds (PhACs) present in the aquatic environment indicates a high potential for further endocrine modes of action on aquatic vertebrates by ED derived from PhACs, such as glucocorticoids, progestins, and ß‐agonists.

Influence of temperature on puberty and maturation of pikeperch, Sander lucioperca.
B. Hermelink,Sven Wuertz,Achim Trubiroha,Bernhard Rennert,Werner Kloas,Werner Kloas,Carsten Schulz +6 more
TL;DR: Moderate temperatures (12-15°C for) for at least 3 months were required to proceed with first maturation in juvenile pikeperch, as revealed by histological as well as endocrine parameters.

Temperature control of pikeperch (Sander lucioperca) maturation in recirculating aquaculture systems—induction of puberty and course of gametogenesis
TL;DR: Postpubertal temperatures around 14 degrees C promoted a complete ripening in pikeperch of both sexes within 8 weeks, whereas higher temperatures constrained full gonadal maturation, indicating the existence of a dynamic temperature influence for optimal maturation due to post pubertal inhibition of maturation at temperatures higher than 18 degrees C.

Photo-thermal manipulation for the reproductive management of pikeperch Sander lucioperca
TL;DR: Both male and female pikeperch initiated reproductive maturation during the wintering phase, which was confirmed through histological analysis and sex steroid measurements, and gonad development and maturation was assessed.

Induction of gonadal maturation at different temperatures in burbot Lota lota
Fabian J. Schaefer,Fabian J. Schaefer,B. Hermelink,P. Husmann,P. Husmann,Wouter Meeus,Jurgen Adriaen,Sven Wuertz,Sven Wuertz +8 more
TL;DR: Less drastic temperature regimes as previously reported in combination with hormone treatments seem sufficient to induce maturation in L. lota after isothermal grow-out, indicated by advanced gonadal stages, higher numbers of oocytes undergoing germinal vesicle breakdown in vitro and elevated sex steroid levels.
