The marination process involves the use of natural preservatives such as salt, vinegar and spices, aiming to enhance flavour and texture. Results demonstrated that marination effectively reduces the rate of increase in total plate count (TPC), trimethylamine nitrogen (TMA-N), total volatile basic nitrogen (TVB-N), pH, peroxide value (PV) and free fatty acids (FFA) during storage, thereby extending the shelf life of the tested samples. Control (C) and marinated (M) samples of vacuum-packed fish steaks remained organoleptically acceptable until the 9 th and 15 th days of chilled storage respectively. Due to the addition of marinating ingredients, significant changes were observed in taste, texture and proximate content. The maximum extension in shelf life for marinated samples is attributed to the combined antimicrobial and antioxidative effects of the different ingredients used in the marination process. These findings suggest that marination holds promise as a method for preserving fish products and satisfying consumer preferences for flavourful, ready-to-cook and economically viable seafood options.

The present study delves into the effect of fermented rice bran as a carbon source on the growth and survival of Genetically Improved Farmed Tilapia (GIFT) fry. Additionally, the study investigated its impact on water quality, intestinal histology, proximate composition of fish and biofloc, total plate count of the experimental tank, and fish gut in the biofloc system. The study employed a completely randomized design with five different treatments: NFRB+BFT (Non-Fermented Rice Bran), FRBW+BFT (Fermented Rice Bran with Water), FRBP+BFT (Fermented Rice Bran with Probiotic), FRBY+BFT (Fermented Rice Bran with Yeast), and a clear-water system (with daily water exchange of 10%). The experimental duration was 60 days. The GIFT fry with an average weight of 1.04 ± 0.02 g were randomly distributed in High Density Polythene (HDPE) tanks of 110 L capacity at a stocking density of 250 individuals (ind.) m − 3. Results indicated that the weight gain %, length gain %, Specific Growth Rate (SGR), and Protein Efficiency Ratio (PER) in FRBP+BFT and FRBY+BFT treatments were similar, with no significant differences (p > 0.05) and significantly higher (p < 0.05) than other treatments. At the end of the experiment, FRBP+BFT and FRBY+BFT treatments showed lower ammonia-N values. The histological study of GIFT showed a number of villi and villi length in FRBP+BFT and FRBY+BFT were similar with no significant differences (p > 0.05). The protein, lipid, and ash content of fish and biofloc were similar with no significant differences (p > 0.05) in FRBP+BFT and FRBY+BFT treatments. The total plate count of fish gut and water in FRBP+BFT and FRBY+BFT treatments was similar and significantly higher (p < 0.05) than the other treatments. Overall, the results indicate that rice bran fermented with both probiotic and yeast as a carbon source showed similar growth performance and improved water quality in rearing GIFT fry in a biofloc system.

Information was collected randomly from 108 shrimp farmers from North Konkan region, Maharashtra using interview schedule. The weighted average technique was used to understand various motivational factors in adherence to act, rules and guidelines given by CAA in shrimp farming. The study revealed that, the top motivating factors were practicing environmentally responsible and socially acceptable coastal aquaculture, minimize impacts on local water resources and minimize impacts on surrounding resource user educing the risks. R associated with shrimp diseases, utilizing land and water resources for sustainable shrimp farming and following better management practices and maximizing economic returns on investment within a reasonable time frame was least motivating factor in adherence to sustainability. The motivation can be enhanced by conducting awareness among shrimp farmers about act, rules and guidelines given by CAA.

The study was conducted in Ratnagiri taluka of Maharashtra to assess the socioeconomic status of trawler operators. The exploration of socioeconomic status involved scrutinizing demographic features, assets holdings, and housing details. An interview schedule was prepared, and data were collected from 102 trawler operators selected through random sampling from December 2022 to April 2023. Data analysis was performed using Microsoft Excel and SAS software. The findings revealed that the majority of trawler operators belonged to the middle age group (57.84%) and had attained education up to primary and secondary levels (32.35%). Moreover, 93.14% of trawler operators were members of a cooperative society. The study concluded that the socioeconomic status of trawler operators was moderately good, evidenced by access to sanitation facilities, electricity supply in their homes, and ownership of immovable assets such as land, houses, boats, and essential movable assets, which collectively signify the wealth of their families.

However, like other organizations, fisheries cooperatives also face constraints and thus this study, explores the constraints faced by them. About 15 per cent (39) functional marine cooperatives from all coastal districts i.e., Mumbai suburban, Mumbai, Sindhudurg, Thane, Ratnagiri and Raigad were selected in proportion to the total number of cooperatives for equal representation from each district and also based on number of members. Pilot study revealed number of constraints faced by marine fisheries cooperative societies. These constraints were categorized in broad groups which were related to limited policy implementation, financial and marketing, fishing grounds, cooperative administration and infrastructure. Interview schedule was administered to head/executive committee members of the cooperative viz. chairperson/secretary/members of Board of Management. Agreement towards constraints was studied using a five point Likert scale which were assigned appropriate weights using consensus based assessment method. Kruskal-Wallis test was applied to test the hypothesis if there was statistically significant difference with respect to constraint faced among districts. It was reported that financial and management constraints were major followed by fishing ground constraints and administration constraints. Statistically significant difference was found between districts for the constraints like lack of basic facilities at landing centre, lengthy documentation for government schemes, poor financial assistance by nationalized banks, conflicts with purse-seine operators, sand accumulation at harbour, conflicts with government officials and poor transportation facility. It is clear from the study that few constraints faced by the cooperatives are same. However, some of the constraints differ among districts and will require interventions specific to districts. Cooperatives can play a proactive role to avail of the schemes provided by the Central and State government especially with respect to the newly formed Ministry of Fisheries by Government of India.

The marine fisheries cooperatives are well established in Maharashtra with the history of over hundred years. In this paper, an attempt has been made to find the organizational roles performed by cooperative societies of Maharashtra for their members. An interview schedule was administered to sample around 15% of cooperative societies i.e. 39 out of 266 functional marine cooperatives. From each coastal district, proportional numbers of cooperatives were randomly selected to the total number of cooperatives to avail the equal representation of cooperatives from each district. The key respondents like Chairpersons, Secretaries, and Members of Board of Management were interviewed. Through pilot study, the organizational roles were categories as handling, processing, marketing, input supply, services, fishery resources management, Facilitating Services (FS), Government Schemes (GS) and Social Services (SS). Kruskal-Wallis test was performed to test the significant difference in organizational roles of cooperatives among districts. The results revealed that, cooperatives perform various roles for their members. Cooperatives of Thane district were found to be involved in maximum organizational roles. It also showed that three organizational roles i.e. spare part supply, allocation of fishing grounds and NCDC scheme extended by cooperatives were significantly different among the cooperatives. The roles performed by cooperatives were strongly limited with administrative setup, financial status and infrastructural development of cooperatives. However, it can be concluded that fisheries cooperatives represent a promising organization that can undertake organizational roles requiring collective action for the development for their members.

Data were collected through an online survey from 1 st July to 30 th July 2020 during the first peak of COVID-19 in the study area by using the questionnaire. Authors based on the latest recommendations by the World Health Organization (WHO) developed the questionnaire and covered the KAP aspects under study. The questionnaire was administered through Google form link and the link was disseminated through social media such as Facebook and What's App. The completed responses (n = 533) received from the eligible sample, excluding those outsides of the fisher community and duplicate entries were considered for analysis. Appropriate statistical tools were used to analyze the data. Among the respondents, 447 men (83.86%) and 86 women (16.14%), with a mean age of 45.4 years (M = 45.4, SD = 1.18). The results revealed that 70.92% of respondents perceived a low risk of infection because of COVID-19 with M = 1.77 and SD = 0.583, but authors found the perceived severity score high (M = 3.95, SD = 1.21) among the 60.97% of respondents. Around 95% of respondents were aware of the COVID-19, while almost all respondents knew the medium of infection and symptoms of COVID-19. The behavior of respondents towards COVID-19 infection was positive and was following sufficient precautionary measures suggested by WHO to protect themselves from COVID-19 infection. The results of multiple regression analysis revealed that the demographic features of respondents like age, education were significantly contributing to the KAP of the fisher community. The results confirmed the importance of KAP which is reflected in the behavioral responses of the fishers while tackling the COVID-19

The fishes (average initial weight 0.57±0.003 g, average initial length 2.84±0.04 cm) were stocked @250nos. m-3 in 110L capacity FRP tanks. The experiment was conducted as per completely randomized design with seven treatments and three replicates for 90 days. Results revealed that the water quality parameters were within suitable range for rearing of GIFT tilapia fry. A significantly higher length gain, weight gain (%) and SGR were recorded in fry reared in rice bran biofloc treatments at the end of 30, 60 and 90 days. One-way ANOVA showed no significant difference (P>0.05) between the survival of GIFT tilapia fry in different treatments. A significantly lower AFCR was found in rice bran biofloc treatment than that of control, but not significantly different from other treatments. Overall, results showed the rice bran as a better source of carbon for rearing of GIFT tilapia fry in biofloc systems.

Kruskal-Wallis test was applied to test the hypothesis if there was statistically significant difference with respect to constraint faced among districts. It was reported that financial and management constraints were major followed by fishing ground constraints and administration constraints. Statistically significant difference was found between districts for the constraints like lack of basic facilities at landing centre, lengthy documentation for government schemes, poor financial assistance by nationalized banks, conflicts with purse-seine operators, sand accumulation at harbour, conflicts with government officials and poor transportation facility. It is clear from the study that few constraints faced by the cooperatives are same. However, some of the constraints differ among districts and will require interventions specific to districts. Cooperatives can play a proactive role to avail of the schemes provided by the Central and State government especially with respect to the newly formed Ministry of Fisheries by Government of India.

Data were collected through an online survey from 1 st July to 30 th July 2020 during the first peak of COVID-19 in the study area by using the questionnaire. Authors based on the latest recommendations by the World Health Organization (WHO) developed the questionnaire and covered the KAP aspects under study. The questionnaire was administered through Google form link and the link was disseminated through social media such as Facebook and What's App. The completed responses (n = 533) received from the eligible sample, excluding those outsides of the fisher community and duplicate entries were considered for analysis. Appropriate statistical tools were used to analyze the data. Among the respondents, 447 men (83.86%) and 86 women (16.14%), with a mean age of 45.4 years (M = 45.4, SD = 1.18). The results revealed that 70.92% of respondents perceived a low risk of infection because of COVID-19 with M = 1.77 and SD = 0.583, but authors found the perceived severity score high (M = 3.95, SD = 1.21) among the 60.97% of respondents. Around 95% of respondents were aware of the COVID-19, while almost all respondents knew the medium of infection and symptoms of COVID-19. The behavior of respondents towards COVID-19 infection was positive and was following sufficient precautionary measures suggested by WHO to protect themselves from COVID-19 infection. The results of multiple regression analysis revealed that the demographic features of respondents like age, education were significantly contributing to the KAP of the fisher community. The results confirmed the importance of KAP which is reflected in the behavioral responses of the fishers while tackling the COVID-19

The fishes (average initial weight 0.57±0.003 g, average initial length 2.84±0.04 cm) were stocked @250nos. m-3 in 110L capacity FRP tanks. The experiment was conducted as per completely randomized design with seven treatments and three replicates for 90 days. Results revealed that the water quality parameters were within suitable range for rearing of GIFT tilapia fry. A significantly higher length gain, weight gain (%) and SGR were recorded in fry reared in rice bran biofloc treatments at the end of 30, 60 and 90 days. One-way ANOVA showed no significant difference (P>0.05) between the survival of GIFT tilapia fry in different treatments. A significantly lower AFCR was found in rice bran biofloc treatment than that of control, but not significantly different from other treatments. Overall, results showed the rice bran as a better source of carbon for rearing of GIFT tilapia fry in biofloc systems.
