“…The study found a significant reduction in growth performance of the fish at higher salinity, 15 ppt group. In freshwater fish, it is proven that higher saline conditions negatively affects its growth and similar results were reported in Clarias batrachus (Sahoo et al 2003) Heterobranchus longifilis (Fashina-Bombata and Busari, 2003) and Nile tilapia (Iqbal et al, 2012). Freshwater fish need to spend more energy at higher salinity to maintain an osmotic balance between the body fluid and external environment leading to reduced growth (Boeuf and Payan, 2001).…”

Background: A 90-day experiment was conducted to study the impact of salinity on growth and physiological response of Pangasionodon hypophthalmus fingerling at the Brackish water fish farm of Central Institute of Fisheries Education (CIFE), Kakinada Centre, Kakinada, East Godavari District, Andhra Pradesh, India. Method: The study used different salinities condition such as 0 (control), 5 (T1), 10 (T2) and 15 (T3) ppt. Fingerlings (8.47±0.46 g) were gradually acclimatized to different salinities in 1000 l fibre reinforced plastic (FRP) tanks, in triplicates and fed with a commercial feed (crude protein 30%). Result: Growth indicators such as specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency ratio (FRR) and protein efficiency ratio (PER) revealed that growth and survival were negatively affected above 10 ppt salinity. Significantly higher amylase and protease activities were observed up to 10 ppt group. In contrast, significantly higher cortisol (97.71±1.94 ng/ml) and glucose (113.32±2.66 mg/dl) levels in the blood were recorded in 15 ppt group. Overall, the study proved that P. hypophthalmus can be cultured in low saline water (up to 10 ppt) without affecting its growth and physiological homeostasis.

“…Likewise, Kuzmina (1996) [15] explained the feeding behavior and biochemical composition of feed could affect the digestive enzyme activity. Khalid and his co-worker (2018) [25] recorded maximum amylase activity in Labeo rohita fed with canola meal while maximum protease activity was recorded in fish fed with cotton seed meal. He also explained that rohu, Labeo rohita fed with guar meal diets showed maximum lipase activity in the whole intestine.…”

The present study was carried out to examine the specific digestive enzyme activity of Nile tilapia (Oreochrmis niloticus) fingerlings, fed with different percentages of Guar sprout meal (GSM). The experiment was set with five isonitroneous and isolipidic diets as T1, T2, T3, T4 and T5 containing guar sprout meal at an inclusion rate of 0, 25, 50, 75 and 100%, respectively. The result showed a higher protease activity in the fish nourished with 0%, 25% and 50%. GSM beyond 50% showed poor protease activities especially in all parts of the gut (gastrointestinal tract). There was significant acceleration in amylase and lipase activities in the digestive tract (liver, stomach and intestine) with increased GSM levels. The results accomplish that 25-50% inclusion of GSM can be a favorable and economically sustainable protein source in the diet of Nile tilapia fingerlings.

“…Intestine of fish comprises mucosa, submucosa, muscularis and serosa layers (Mokhtar et al, 2015). According to Ozel et al (2018), mucosal layer is composed of epithelium, lamina propria and muscularis mucosa (Mumford et al, 2007) and could be influenced by biotic and abiotic factors (Khojasteh, 2012) such as species and diet (Raskovic et al, 2011;Iqbal et al, 2018), feeding pattern, body shape and age (Cao et al, 2011).

The search for alternative protein sources in aquaculture nutrition is still trending as the use of costly traditional feed stuffs in aquaculture diet formulation is no longer sustainable. The present study investigated the effects of partial and total dietary inclusion of cashewnut meal on growth, haematology, carcass composition, serum biochemistry and intestinal histology of juvenile African catfish Clarias gariepinus (Burchell, 1822). Soybean meal (SBM) was substituted with cashewnut meal (CM) at 0, 50 and 100% in formulated fish diets. A total of 135 juveniles of C. gariepinus (30.25± 1.02 g; 16.08±0.34 cm) were randomly assigned to three dietary treatments (0, 50 and 100% CM based diets) at a stocking density of 45 fish per treatment and further randomised into triplicates of 15 fish per replicate. The feeding trial lasted for 56 days and fish were fed twice daily at 5% body weight. Statistical analysis was carried out for all the parameters evaluated in this study. Fish group fed 50% CM based diet had the best growth performance and haematological profile when compared to 100% CM fish group and the control group. Insignificant changes in serum biochemical parameters were observed in CM fed fish groups when compared to the control. Histological examination of fish intestinal morphology revealed no adverse changes in the cellular structure of mucosal layer and villi in 50% CM fed fish, while mild histo-morphological changes were observed in 100% CM fed fish group. Significant increases in villi length and weight were observed in fish group fed CM based diets when compared to the control. The findings of the present study revealed that partial replacement (50%) of soybean with cashewnut meal improved growth performance and haematological profile of C. gariepinus.
