Abstract

The Sustainable Development Goals (SDGs) emphasize gender equality and women’s empowerment as essential to global development, particularly in sectors that support food security and economic growth, such as aquaculture. This study investigates women’s empowerment levels in aquaculture within Self-Help Groups (SHGs) in Southern Odisha, using an improved Women Empowerment in Aquaculture Index (WEAI). Data were collected from two Self-Help Groups (SHGs) in each of the Gajapati and Rayagada districts, measuring empowerment across six domains: “access to and control over resources and services”, “participation in social and economic activities”, “ability to decide independently”, “control over use of income”, “knowledge on aquaculture”, and “attitude towards aquaculture”. Findings revealed significant variability in empowerment levels, where “control over use of income” being the highest among the domains. In contrast, “participation in social and economic activities” and “knowledge of aquaculture” were notably lower. Path analysis highlighted the importance of participation in extension activities and access to information in driving empowerment, while factors like innovativeness require better support. Garrett’s ranking method identified critical constraints such as “Lack of financial support from the Govt. organisations”, “high cost of feed”, and “lack of need-based training programme” having regional variations between Gajapati and Rayagada. The study concludes that a multifaceted approach is essential to promote empowerment, including localized training, enhanced resource access, and targeted policy support. Future research should aim to refine empowerment strategies to encourage both individual women’s and community growth in aquaculture.

Abstract

The current study investigates the combined effect of different dietary vitamins E and selenium (sodium selenite, Se) on the growth, survival, feed utilization, nutrients digestibility, body composition, activity test evaluation, intestinal bacterial load, and hematological indices of European seabass, Dicentrarchus labrax fry. A feeding experiment was conducted in D. labrax using five different diets with the same proximate composition. Introvit-ES100 oral® (ES) provides 50 mg/mL vitamin E and 0.5 mg/mL selenium, a source of VE and Se. The only distinction between the diets was the level of VE and SE. Each diet was fed to triplicate groups of fish (initial weight: 0.13 g) for 84 days. The control diet (ES₀%) did not contain any added ES. Diets 2–5 included varying: 50: 0.5 mg/kg (ES₁%), 100: 1.0 mg/kg (ES₂%), 150: 1.5 mg/kg (ES₃%), and 200: 2.0 mg/kg (ES₄%). The water quality parameters were temperature 22, with a pH range of 7.9–8.2, the salinity range is 31.3–32.4 ppt, and the nitrogen concentrations are as follows: N at 0.54, NH₃ at 0.73, and NH₄ at 0.77. The results showed that seabass fry had the highest FBW, WG, SGR, FL, and K values when fed 150: 1.5 mg kg⁻¹ of VE and Se, respectively (ES₃%). Fish provided the ES₄% diet had the highest survival (%) and showed inferior growth performance. Apparent digestibility coefficient analysis, which included protein, lipid, and carbohydrate digestibility, revealed that the highest values were recorded in fish fed the ES₃% diets. The highest body protein was recorded in ES₃%; the lowest lipid content value was recorded in ES₄%. The highest white blood cell count, red blood cell count, and hematocrit values were recorded in ES₃%. While the highest hemoglobin values were recorded in ES₄%. The highest activity test value was recorded in ES₂% and ES₃% diets. The lowest Vibrio sp. count was recorded in ES₃%. While the Aeromonas sp. was not detected in all experimental treatments. The results indicated that supplementing the diet with 150 mg kg⁻¹ of VE and 1.5 mg kg⁻¹ of Se improved growth performance, feed utilization, and survival rates, resulting in increased production of D. labrax fry after weaning in marine hatcheries.
