“…sinensis , hence reduced energy consumption on osmoregulation [ 10 , 36 ], resulting in more nutrients/energy being channeled to gonadal development [ 37 ]; 2) certain ions, such as calcium, are substantially higher in brackish water, which may have the function in stimulating gonadal development of crustaceans [ 14 , 38 ]. Previous studies have also shown that ovarian development of several marine crustaceans were delayed at low salinities [ 39 – 40 ], which might be due to these crustaceans having to spend much of energy for osmoregulation, hence leading to poor gonadal development [ 40 – 41 ].…”

As a catadromous species, salinity is a key parameter that affects gonadal development of Chinese mitten crab Eriocheir sinensis during reproductive migration. It is however unclear the effects of salinity on the gonadal development of male E. sinensis as well as their physiological responses to salinity during reproductive migration. This study investigated the effects of four salinities (0 ‰, 6 ‰, 12 ‰ and 18 ‰) on gonadal development, osmoregulation and metabolism of adult male E. sinensis over a 40-day period. The results showed that elevating salinity promote gonadal development, increase hemolymph osmolality and K+ and Mg2+ concentrations (P < 0.05). The 12 ‰ salinity resulted in the highest contents of taurine and arginine in the hemolymph while the highest contents of threonine, phenylalanine, lysine, ß-alanine, tryptophan, ornithine and total free amino acids were found for 0 ‰ treatment (P < 0.05). A decreasing trend was detected for the Na+/K+-ATPase activity and its mRNA expression level in the posterior gills with salinity (P < 0.05). Total saturated fatty acids in the anterior gills decreased with increasing salinity (P < 0.05); the 0 ‰ treatment had the highest total polyunsaturated fatty acids in the posterior gills while total n-6 polyunsaturated fatty acids increased with salinity (P < 0.05). The hemolymph glucose and uric acid showed a decreasing trend as salinity while an increasing trend was found for the hemolymph triglyceride and high-density lipoprotein cholesterol (P < 0.05). The 12 ‰ treatment had the highest levels of hemolymph malonaldehyde and hepatopancreatic γ-glutamyltranspeptidase (P < 0.05). In conclusion, these results suggested that the brackish water promote gonadal development of male E. sinensis, and increase osmolality and ionic concentrations in hemolymph while reduced the activity of Na+ /K+- ATPase and its mRNA expression in the posterior gills as well as metabolism.

“…In the Gulf of Gdańsk it usually overwinters at depths of 20-40 m, whereas in summer it accumulates in large numbers in warm shallow waters, often at depths from 0.2 to 5.0 m (Żmudziński & Ostrowski, 1990). With the onset of the reproductive period, the females move off to deeper waters (Boddeke, 1976;Gelin et al, 2001). The seasonal migration pattern in P. elegans is similar: offshore in autumn, and back to shallower waters in spring (Kobyakova & Dolgopol'skaya, 1969).…”

This study concerns the environmental requirements of the shrimp, Crangon crangon, and the prawns, Palaemon adspersus and Palaemon elegans, which occur in the Gulf of Gdańsk. Specimens were sampled from the 0.5-1.0 m and 5.0-10.0 m depth layers in the southwestern part of the Gulf, near the seaside resort of Sopot, in 2002Sopot, in -2003. The dominant species was C. crangon, the largest concentrations of which were recorded at 5.0-10.0 m. Seasonal changes were observed in the composition of the population of these three species during the year. P. elegans, a relative newcomer to the Polish zone of the Baltic Sea, has occupied a vacant ecological niche (the 0.5-1.0 m depth zone) and in doing so, has avoided competition with the native C. crangon. In the littoral zone (0.5-1.0 m) off Sopot, and also off Hel and Gdynia, P. elegans occurred together with P. adspersus. The diverse requirements of these three species with respect to biotic (e.g., food) and abiotic factors (e.g., substrate, dissolved oxygen) enable them to coexist in the waters of the Gulf of Gdańsk. RÉSUMÉCette étude concerne les exigences environnementales des crevettes Crangon crangon, Palaemon adspersus et Palaemon elegans, qui sont présentes dans le golfe de Gdańsk. Les spécimens ont été récoltés à 0,5-1,0 m et 5,0-10,0 m de profondeur dans la partie sud-ouest du golfe, près de la station balnéaire de Sopot, en 2002de Sopot, en -2003. L'espèce dominante était C. crangon, dont les effectifs les plus élevés ont été trouvés à la profondeur de 5,0-10,0 m. Des variations saisonnières ont été observées dans la composition de la population de ces trois espèces au cours de l'année. Présent depuis peu dans la zone polonaise de la mer Baltique, P. elegans a occupé une niche écologique vacante (la zone de profondeur 0,5-1,0 m) et a ainsi évité la compétition avec l'espèce autochtone C. crangon. Dans la zone littorale (0,5-1,0 m) au large de Sopot, et également au large de Hel et Gdynia, P. elegans est présent avec P. adspersus. Les exigences différentes de ces trois espèces par rapport aux facteurs biotiques (nourriture) et abiotiques (nature du fond, oxygène dissous) leur permettent de coexister dans les eaux du golfe de Gdańsk. 1 )

“…Besides temperature and rainfall, variations in salinity may influence the reproduction of decapod crustaceans, affecting the survival and reproductive cycle of females (Gelin et al 2001;V asquez et al 2013). However, in the Pacific where salinity varied significantly among the studied sites, this environmental parameter does not seem to be an important trigger for the onset of the reproductive period.…”

The mangrove crab Aratus pisonii was considered to have an amphi‐American distribution; however, a recent study revealed that the Eastern Tropical Pacific populations were genetically distinct, thus representing a new species: Aratus pacificus. These species separated by the Isthmus of Panama have diverged under different environmental conditions that may have influenced their reproductive biology. As the available information about this genus concerns almost exclusively the Caribbean species, the aim of the present study was to analyse and compare reproductive aspects of A. pacificus and A. pisonii obtained from both the Pacific and Caribbean coasts of Costa Rica. Females were collected from April 2011 to April 2012, and reproductive features such as breeding season, size distribution of ovigerous females, fecundity, reproductive output, embryo volume and embryo water content were assessed. Both species produced embryos during the entire sampled period. Most females of A. pacificus carrying embryos close to hatching were found during the rainy season. Ovigerous females of A. pisonii were substantially larger and reached sexual maturity at a larger size than females of A. pacificus. Embryo production started in A. pacificus at a smaller female size than in A. pisonii. As fecundity increased with female size, the average fecundity was lower in A. pacificus. Females of A. pisonii produced larger embryos, which might be related to lower food availability: higher energy content in the embryo enhances the chances of larval survival. These data regarding reproductive features of the Pacific and Caribbean species support the conclusion to separate A. pacificus from A. pisonii.
