“…Salinized water as a strategy for increase stocking density in Heros severus larviculture, an Amazonian ornamental fish 20 larvae L -1 in 3 g L -1 of salinized water presented the higher growth values. These results may be related to the reduction of the osmotic gradient, between farmed water and fish plasma, which leads to a reduction in energy requirement for osmoregulation (Salaro et al, 2012;Fabregat et al, 2015), redirecting that energy to other physiological processes, such as fish growth (Fisher et al, 2021;Freire and Sampaio, 2021). Furthermore, adequate levels of salinized water can reduce the toxic effect of ammonia and nitrite, contributing to improving the welfare of the fish and decrease the toxicity of the nitrogenous compounds (Sampaio et al, 2002).…”

“…In addition, the increase in water salt concentration decrease the ionic difference between water and fish plasma, which reduce the energy expenditure by freshwater fish to maintain its osmotic equilibrium (Salaro et al, 2012;Fabregat et al, 2015). The fish larval can redirected this energy to other physiological processes, such as fish growth, immunity and stress responses (Fisher et al, 2021;Freire and Sampaio, 2021). Salinized water also reduces the toxicity of nitrogenous compounds (Sampaio et al, 2002) and prevents the occurrence of some fish diseases and parasites (Garcia et al, 2007;Santos et al, 2020).…”

The aim of this study was to evaluate the effect of different salinized water (0, 3 and 6 g L-1) and stocking densities (10, 15 and 20 larvae L-1) in Heros severus larviculture. The experimental design was completely randomized, in a 3x3 factorial design, with three replicates. For this, a total of 405 larvae of H. severus were randomly distributed in 27 aquariums (1L) according to the treatments and after 15 days all the larvae were measured, weighed and counted. Higher values for final length, length gain and specific growth rate were observed in H. severus larvae raised at any stocking density tested at 3 g L-1 of salinized water (p < 0.05). The final weight and weight gain followed the same trend of the length, being higher in fish submitted to 3 g L-1 of salinized water (p < 0.05). On the other hand, the salinized water of 6 g L-1 was detrimental to larvae weight uniformity and survival rate (p < 0.05). The fish stocked at densities of 15 or 20 larvae L-1 presented the best results of final weight and weight gain (p < 0.05). The stocking density of 20 larvae L-1 in salinized water at 3 g L-1 is recommended for H. severus larviculture.

In recent years, the production of economically important crustaceans, and decapods in inland saline areas has increased considerably. The osmoregulatory capacity of these decapods renders them culturable in wide salinity ranges, contributing to a global industry valued at billions of dollars. Therefore, gaining insights into the fundamental mechanisms that drive the adaptive capacity of crustaceans to thrive in diverse salinity ranges is essential. This comprehensive review paper unveils the pivotal adaptations of decapods that allow them to flourish in diverse salinities, ranging from freshwater to saline waters. This article discusses the molecular mechanisms of osmoregulation in decapod crustaceans with more emphasis on Litopenaeus vannammei. Moreover, the importance of maintaining an ideal osmotic balance for efficient digestion and nutrient absorption in L. vannamei is discussed. Furthermore, the effect of salinity on disease resistance in these species is explored, highlighting the need for effective disease management in aquaculture. Overall, this review explores the multifaceted factors influencing decapod crustaceans' adaptation to shifting salinities and also emphasizes the ongoing need for continued research in this domain.
