A 90-day study was conducted to investigate the effects of substituting sunflower oil (SFO) for fish oil (FO) on various parameters in Labeo rohita (initial weight 18.21 ± 0.22 g). Five experimental diets with different levels of SFO (up to 7%) substitution for FO (0%, 25%, 50%, 75%, and 100%) were formulated, ensuring equal levels of nitrogen and lipids. The results indicated that even with 100% substitution of SFO with FO, there were no significant differences (P>0.05) were observed in growth performance. The survival rate (SR), hepato-somatic index (HSI), and viscero-somatic index (VSI) as well as whole-body composition were also nonsignificant by SFO substitution. However, the fatty acid profiles in both muscle and liver were influenced (P<0.05) by dietary substitution. Saturated fats (SFA) decreased, while monounsaturated fats (MUFA), and linoleic acid (LA) increased (P<0.05). On the other hand, the contribution of linolenic acid (ALA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) decreased (P<0.05) as the amount of SFO in the diet increased. Hematology parameters, including red blood cells (RBCs), hemoglobin (Hb), and hematocrit (Hct), were not affected. Globulin (GLO) levels decreased significantly (P<0.05), while alanine transaminase (ALT) and aspartate transaminase (AST) activity showed nonsignificant increases (P>0.05). Total protein (TP) increased (P<0.05) at 100% SFO inclusion in the diet, and albumin (ALB) levels increased (P<0.05) at 75% and 100% SFO inclusion in the diet. Cholesterol (CHOL), triacylglycerol (TG), and high-density lipids (HDL) were not significantly affected (P>0.05), while low-density lipids (LDL) were significantly increased (P<0.05) compared to the control group. Cortisol (CORT) and glucose (GLU) levels showed nonsignificant (P>0.05) changes. Superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) activities in the liver and serum were not significantly (P>0.05) affected, while malondialdehyde (MDA) status was significantly (P<0.05) reduced. In conclusion, the fatty acid profile of the muscle and liver of fish was modified by the diets, and FO can be substituted with SFO up to 100% for L. rohita, which is beneficial for growth and immunity while marinating the lipid contents in fish. Our study revealed that fully replacing fish oil with SFO shows promise in fully replacing FO without compromising the growth and overall health status of the fish.

“…One of the most common measures of fish general health problems is haematological indices. Prior research has demonstrated the beneficial benefits of the FO: SO ratio on fish immunological responses, haematological, and antioxidative responses in both marine and freshwater fish (Reda et al, 2020;Agh et al, 2020). Our results indicated that after feeding keeled mullet Liza carinata fingerlings for 60 days, increasing the dietary SO content at the expense of FO had no adverse impact on haematological markers.…”

“…Despite the significant difference in the values of blood parameters, they were all within the safe limit values. Reda et al (2020),reported that switching from FO to plant oil had no adverse effects on O. niloticus's haematological markers. Additionally, there were appreciable differences in RBC, MCV, and RDW-SD (fL) values across diets containing varying levels of FO; however, SO addition to feeding increased values of RBC, MCV, and RDW-SD (fL) in keeled mullet.…”

the nutritional strategies developed to bridge the gap between supply and demand for animal protein from seafood, but this development must be sustainable (Aboseif et al., 2022 a,b; Flefil et al., 2021). Fats are important in the aquaculture feed industry, as they are the main source of essential FA and provide energy for fish (Wang et al., 2022; Zorlu et al., 2022). Fish oil (FO) is the primary ideal lipid source in aquatic feeds which is high in n-3 long-chain polyunsaturated fatty acids (n-3LC-PUFA) such as eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid DHA, 22:6n-3 (Fukada et al., 2020;He et

“…Although sh species own the ability to adapt to gradual temperature variations (Wang et al, 2022), sharp changes commonly lead to sublethal disorders and even mortality (Bacchetta et al, 2020). A rapid decline in water temperature, namely cold shock, has negative effects on metabolic processes (Islam et al, 2021;Jiao et al, 2020;Zhang et al, 2021), swimming ability (Szekeres et al, 2014), antioxidant and immune systems (Ale et al, 2021;Reda et al, 2020;Wen et al, 2018;Singh et al, 2021), and ultimately result in cellular apoptosis (Cheng et al, 2017). Furthermore, several documented events, referred to as "winterkills", have occurred in wild and cultured sh populations (Doménech et al, 1997;Hoag, 2003;Conover et al, 2006), which lead to episodic die-off of sh and great economic losses.…”

As global climate changes, severely temperature variations have significant impacts on survival and development of fish. While the potential effects of light wavelength on cold shock and associated mechanisms remain largely unknown in fish. Here, zebrafish were pre-exposed to white LEDs (an irradiance of 0.9 W/m2) and blue LEDs (LDB, peak at 450 nm, 0.9 W/m2) for 2 weeks, and then exposed to 26℃ or 11℃ for 48 hours, respectively. Cold shock led to low survival rate. Cold shock altered retinal structure, increased the number of apoptotic cells and Caspase-3 activity, inhibited superoxide dismutase (SOD) and catalase (CAT) activities, up-regulated mRNA expression of (NF-E2-related factor 2) nrf2, p53, casp3 and casp9, and down-regulated cat expression in fish eyes. These results demonstrated that acute cold exposure induced oxidative stress and apoptosis in zebrafish eyes, which may lead to mortality. However, cold shock in combination with LDB apparently mitigated these negative effects, which might be involved in the up-regulation of antioxidant response and down-regulation of apoptotic responses at transcriptional and translational levels. Furthermore, cold shock also caused dysregulation of genome-wide gene expression involved in circadian rhythm, phototransduction and il-17 signaling pathway, indicating that cold shock disturbed phototransduction cascade and circadian rhythm signals and caused inflammatory responses. Ten key genes involved in circadian rhythm, phototransduction, cell cycle arrest, RNA processing or inflammatory responses were identified, including muc5d, rnps1, si:dkey-243i1.1, opn1mw1, gadd45ba, cebpd, btg2, si:dkey-242g16.2, nr1d1 and zgc:122979, which may play an important role in the protection of LDB against cold shock. Finally, our study suggested the relationship between spectrum and cold stress and demonstrated LDB could protect fish against the negative effect of cold stress in the eyes.
