“…Decreasing survival rates with increasing salinity level are characteristics of stenohaline freshwater fish due to increasing osmotic pressure at higher salinities (Kilambi & Zdinak, 1980). It has been reported that salinity levels more than 6‰ showed higher mortality and reduced growth rate in fingerlings of Heteropneustes fosslis (Ahmmed et al, 2017). On the other hand, salinity level ≥9‰ negatively affected the growth of goldfish (Altinok & Grizzle, 2001).…”

Summary Salinity intrusion in the coastal freshwater rivers due to climate change and construction of the dam in the upstream rivers are alarming in aquaculture. Hence, an experiment was conducted to know the effects of salinity on growth performance, hemato‐biochemical parameters and erythrocytes structure in a commercially cultivable catfish species, striped catfish (Pangasianodon hypophthalmus). Firstly, median lethal concentration (LC50) of salinity for striped catfish was determined and then the fish were exposed to three salinity conditions (4, 8 and 12‰) and a control (0‰). Fish were sacrificed at day 7, 14, 28 and 56 after the start of salinity exposure. The 96 hr LC50 value was found to be 14.87‰. Salinity levels from freshwater to 8‰ showed optimal conditions with high survival rate and good growth performances of fish in terms of weight gain and specific growth rate (SGR). Interestingly, the lowest food conversion ratio (FCR) was found in 4‰ group. The hemoglobin (Hb) level and number of red blood cells (RBCs) were found to be decreased significantly in 8 and 12‰ compared to 0 and 4‰ at the initial days of exposure, while number of white blood cells (WBCs) and glucose level showed opposite scenario. Frequencies of ENA (erythrocytic nuclear abnormalities) and ECA (erythrocytic cellular abnormalities) were significantly increased with increasing salinities in the initial days of exposure. Overall, findings of the present study revealed that striped catfish might be suitable fish species for culture in the brackish water containing salinity up to 10‰.

“…This indicates that the tested salinities were well within the optimal range of LFBH because Ahmmed 2017). This is generally believed to be in response to increase energetic costs associated with osmoregulation and/or a disruption to metabolism (Febry and Lutz, 1987).…”

“…Indeed, survival and growth linearly decreased from 0 -14 ppt in snakehead, fry (Amornsakun 2017) and 0 -9 ppt in the freshwater catfish, fingerlings (Ahmmed 2017) and fry (Romano 2017). These fish species could, therefore, be described as stenohaline freshwater.…”

Aim: Methodology:Results: Interpretation:Interest in lemon fin barb hybrid (LFBH) aquaculture has been increasing, but there is limited information regarding optimal nursery conditions.In this study, LFBH fry (initial mean weight = 1.3 ± 0.2 cm) were subjected to increasing salinities of 0, 3, 6 and 9 ppt. Each treatment was triplicated with 15 fish in each replicate. After 30 days, the survival, growth and whole-body histology was examined.No mortalities occurred over the study duration, but there was a significantly positive relationship (p < 0.001; R = 0.996) between salinity and specific growth rates for weight. Salinity had no adverse effect on the gill or internal organ structure, as well as no effect to the prevalence of gill mucous cells. However, there appeared to be slightly more liver glycogen in fish subjected to 6 and 9 ppt. This study demonstrates the euryhalinity of LFBH over the more stenohaline characteristic of their parent, The euryhalinity of LFBH should provide more flexibility in their culture, such as polyculture with other brackish water species, as well as in areas experiencing increase salinization. Therefore, LFBH may provide greater food security in some areas. 2Barbodes gonionotus.

“…Human activities, such as agriculture and salt mining are also increasing saline concentrations in inland freshwater (Venancio et al, ). Salinity heavily affects the overall homoeostasis of both euryhaline and stenohaline fish (Acharjee et al, ; Ahmmed et al, ; Hyatt et al, ; Lisboa, Barcarolli, Sampaio, & Bianchini, ). Stenohaline fish have narrow salinity tolerance and inhabit environments of steady salinity concentration.…”

“…The present study was carried out to elucidate the effect of saline exposure on the female reproductive organ, ovary, of a stenohaline freshwater fish, Heteropneustes fossilis (Bloch, 1794) . H. fossilis is an air‐breathing stinging catfish of India that can flourish in various adverse ecological conditions due to its air‐breathing nature (Ahmmed et al, ; Ali et al, ). This fish is commercially important for its high demand as food.…”

Exposure to salinity stress cause ovarian disruption in a stenohaline freshwater teleost, Heteropneustes fossilis (Bloch, 1794)

Stenohaline freshwater fish with narrow salinity tolerance are susceptible to saline stress from global climate change and anthropogenic activities. The present study elucidated that saline exposure during the sensitive window of preparatory phase of oocyte maturation significantly affected gonadosomatic index, ovarian histology and morphometric features of oocytes in a stenohaline freshwater catfish, Heteropneustes fossilis (Bloch, 1794) in a dose (2 ppt, 5 ppt)—and duration (8, 24 days)‐dependent manner. The gonads of H. fossilis show annual maturation cycle. Loss of integrity of ovigerous lamellae, disruption of ovarian stroma, disrupted oolemma, ooplasmic vacuolization, damaged germinal vesicles and altered morphometry of previtellogenic oocytes, such as chromatin‐nucleolus, early perinucleolar and late perinucleolar, elucidated consistent effects of saline exposure except at 8 days exposure to 2 ppt of saline. Increased salinity might have affected the transmembrane ion/water transport and disrupted the osmotic balance in ovary that eventually led to impairment in growth of ovary and oocyte maturation. The susceptibility of ovary to comparatively less concentrations of saline exposure might be due to sensitiveness of ovary/oocytes during the early phase of growth. Fluctuating salinity along with other stressors can affect metabolic and growth rates, fecundity and ultimately survival of fish.
