TLDR
The findings suggest that the synthesis and secretion of the two tPRLs could be independently regulated in the same cells.About:

Journal ArticleDOI
The role of prolactin in fish osmoregulation: a review.
TL;DR: Much of the recent work has focused on the isolation and characterization of fish PRLs and their receptors, which have provided the necessary tools to obtain a better understanding of the evolution of PRL and its role in osmoregulation.

Physiological and Respiratory Responses of the Mozambique Tilapia (Oreochromis mossambicus) to Salinity Acclimation
TL;DR: The results of this study indicate that the physiological changes associated with SW acclimation in tilapia represents a significant short-term energetic cost, and may account for as much as 20% of total body metabolism after 4 days in SW.

Reproductive physiology of female tilapia broodstock
K Coward,N. R. Bromage +1 more
TL;DR: Current understanding of the reproductive physiology of tilapia is reviewed with particularemphasis upon those factors deemed critical to successful broodstock management, such as fecundity, egg size, spawning periodicity, ovarian development and the endogenous and endogenous regulatory mechanisms involved in their control.

Osmoregulatory Actions of Growth Hormone and Prolactin in an Advanced Teleost

TL;DR: Tilapia PRLs (PRL177 and PRL188) increased plasma osmolality in 100% seawater and reduced gill Na+,K(+)-ATPase activity, the effects induced byPRL188 being more significant than those by PRL177, indicating GH may be involved in seawater adaptation of tilapia, a species belonging to the most advanced teleost super-order.

Effects of fasting on growth hormone/insulin-like growth factor I axis in the tilapia, Oreochromis mossambicus.
TL;DR: Plasma IGF-I levels were correlated significantly with specific growth rate, condition factor and hepatosomatic index, indicating that plasma IGF- I is a good indicator of growth in the tilapia.
