- ItemAdoption of good management practices by aquafarmers(Society of Fisheries Technologists (India), Cochin, 2009) Jeeva, J.C.; Balasubramaniam, S.; Srinath, K.The study was conducted among the aquafarmers in four selected districts viz., Trichur, Alleppey, Ernakulam and Kannur in Kerala. Data were collected on the extent of adoption of good management practices among the sample respondents. Of the 10 practices evaluated, the adoption scores were higher for six practices viz., preparation of ponds (93.15%), eradication of predators and weeds (85.39%), use of PCR tested seeds (84.47%), use of recommended feeding schedule (77.63%), water exchange and quality monitoring (71.69%) and harvesting after prescribed days of culture (70.32%). The extent of adoption of each practice varied significantly (p < 0.01) among the aquafarmers with the overall mean adoption score of 70.09% (n=73). The variables viz., number of training programmes undergone, number of information sources utilized and expert services availed, were found to have positive relationship with the extent of adoption. Regression analysis revealed that of the seven variables, only one variable viz., number of training programmes undergone had contributed significantly (p < 0.05) towards the extent of adoption of improved practices.
- ItemAdoption of quality management practices in seafood processing sector in cochin region(Society of Fisheries Technologists (India), Cochin, 2012) Balasubramaniam, S.; Jeeva, J.C.; Ashaletha, S.The study was conducted in 34 fish processing units in Ernakulam and Alleppey districts of Kerala, India. Data were collected on the general profile of the seafood processing units, availability of infrastructural facilities and managerial role performance of fish processors. The results revealed that 76.47% of the units were EU approved and 23.53% were Non-EU units. The average quantity handled per day was 11.12 t while the production capacity was 21.51 t day super(-1). For the availability of infrastructural facilities in the processing units, the adequacy index was more than 90. The overall role performance index of the fish processors was found to be 74.46. The adoption of quality management practices was determined in terms of good hygienic practices (Mean: 99.51%), good manufacturing practices (Mean: 97.65%), standard sanitation operation procedures (Mean: 99.08%) and good laboratory practices (Mean: 96.33%). The significant 'F' value in the multiple regression analysis revealed the overall significance of influence of 14 independent variables when taken together in explaining the extent of adoption of good hygienic practices by the fish processing units. Of the fourteen variables, only type of approval and adequacy of infrastructural availability in the processing units positively contributed towards the extent of adoption of quality management practices. The R super(2) value indicated that the 14 variables selected together explained 67.70% of variation in the adoption level. The major constraints expressed by the processors were also listed out.
- ItemAnalysis of socio-economic variables and impact of tsunami among the mechanized boat operators in tamilnadu(Society of Fisheries Technologists (India), Cochin, 2012) Jeeva, J.C.; Balasubramaniam, S.; Ashaletha, S.; Jeyanthi, P.The post-Tsunami fisheries scenario and socioeconomic conditions among the mechanized boat operators in Tamilnadu, India were studied. The data were collected from a randomly selected sample of 60 mechanized boat operators from Cuddalore and Nagapattinam districts (30 per district) in Tamilnadu, India. The average fishing days in a year was 217 and 213 for Cuddalore and Nagapattinam respectively. The average investment on fishing unit was Rs 15.50 and Rs 16.38 lakhs respectively in both the centres. Almost all the respondents in both the districts reported no change in various parameters viz., demand for fish, price of fish, change in the taste or quality of fish, urbanization/migration and changes in health, sanitation, nutritional status and outbreak of any disease after Tsunami. Increased fishing pressure, introduction of steel trawlers, ring seine operation, large mesh trawls, double-rig trawling, single-day to multi-day fishing, larger boats and usage of electronic instruments were found to be the major changes in the post-Tsunami period. Significant changes could be observed in the present value of craft and gear, investment and indebtedness in the pre and post-Tsunami periods. Majority of the respondents in both the study areas expressed satisfaction with the adequacy of mitigation measures such as supply/replacement/repair of fishing devices, technological assistance, credit facilities, health and hygiene.
- ItemCommunication behaviour of traditional fishermen(Society of Fisheries Technologists (India), Cochin, 1993) Balasubramaniam, S.; Mohan, B.; Kandoran, M.K.This paper analyses the communication behaviour of traditional fishermen operating motorised and non-motorised crafts. The results revealed that among the 12 independent variables, technological gap variable had negative correlation with the communication behaviour of fishermen operating motorised crafts. For the fishermen operating nonmotorised crafts, information need had positive correlation and the variable experience had significant positive influence on their communication behaviour. Further, the results revealed the socio-personal and technological characteristics of fishermen who had low and high communication behaviour scores.
- ItemDecision making behaviour of traditional fishermen in relation to the adoption of improved fishery technologies(Society of Fisheries Technologists (India), Cochin, 1992) Balasubramaniam, S.; Kandoran, M.K.; Mohan, B.This study investigates the decision-making behaviour of traditional fishermen in relation to the adoption of improved fishery technologies. Out of eight quantitative variables studied, education and number of crew members had significant and positive correlation with their overall decision making behaviour. In the multiple regression analysis, the R super(2) value was 0.2718 and non-significant. Further, the inter-personal sources played a crucial role in the decision-making process of fishermen.
- ItemDiscriminant analysis of selected variables in the adopition of fish curing(Society of Fisheries Technologists(India),Cochin, 1984) Balasubramaniam, S.; Kaul, P.N.Discriminant functions were worked out for adoption or non-adoption of five improved practices in fish curring. Four variables measured quantitatively formed the basis for discrimination. In four out of five equations, the selected variables were found to discriminate significantly between the adopters and non-adopters.
- ItemEvaluation of information needs of fish processors(Society of Fisheries Technologists(India),Cochin, 1999) Balasubramaniam, S.; Thomas, M.; Kandoran, M.K.Technological information needs of fish processors were studied by selecting a sample of 43 fish processors. The results revealed that the mean information need index was 63.60%. Though the average information need quotient (INQ) values ranged from 52.90 to 82.79 for the five major subject areas, the 'F' was found to be non-significant (F=1.53). Of the 40 specific subject items, the INQs were high (86.05 to 100) in ten subject items while they were low (23.6 to 37.21) in seven subject items. It was seen that the variables viz. type of processing unit, production capacity and number of freezers were found to have positive association with information need.
- ItemFish catch variations and associated variables among fishermen operating plank-built crafts(Society of Fisheries Technologists(India),Cochin, 2003) Balasubramaniam, S.; Ramesan, M.P.; Gopal, N.The fish catch variations in terms of the quantity of catch per day and the socio-personal variables of fishermen operating plank-built crafts (15-17 m) were analysed in three fishing centres. Of the 15 socio-personal variables, there were no significant differences between the artisanal fishermen respondents. The overall average fish catch for three centres varied between 526.81 to 533.46 kg per day of fishing among the fishermen and statistically, the fish catch differences were not significant between the fishing centres over a period of five months. In the correlation analysis, five variables viz., investment on craft; investment on net, investment on engine, size of fishing net used and total engine hp used were found to have significant positive correlation with the fish catch variation levels. In the regression analysis, R super(2) value was high (74.11%) and non-significant. Further, the independent variables including the fish catch variation levels did not have significant positive association with the innovation proneness index scores.
- ItemFish productivity and associated factors among fishermen operating FRP crafts(Society of Fisheries Technologists(India),Cochin, 2005) Balasubramaniam, S.; Ramesan, M.P.; Gopal, N.The socio-economic variables of artisanal fishermen in Veraval (Gujarat) and Quilon (Kerala) are presented. Variables such as size of craft operated, fishing experience, annual maintenance cost of craft, net and engine, sale value of fish catch obtained per fishing day and annual income did not vary significantly between the fishermen in Veraval and Quilon fishing centers. The results revealed that on an average, the fishermen at Quilon had obtained a fish productivity level of 155kg per fishing day with a value of Rs. 1,794/-. For the fishermen at Veraval center, the fish productivity level was 91.5 kg per fishing day with sale value of Rs. 1,690/-. The multiple regression analysis revealed that the 13 variables taken together had significantly accounted for about 96 per cent of the variation in the fish productivity levels at both centers. The constraints reported by these fishermen operating smaller FRP crafts (8-9 m LOA) were recorded.
- ItemSocio-personal characteristics of fishermen operating marine plywood craft in Kerala(Society of Fisheries Technologis(India), 1994) Balasubramaniam, S.; Kandoran, M.K..; Braj MohanThis paper analyses the socio-personal characteristics of fishermen who operate the marine plywood crafts in Kerala, India. The comparative profiles of the fishermen operating marine plywood crafts, dugout canoes and plank-built crafts are presented. The results revealed that the fishermen operating marine plywood crafts had higher mean scores on annual income, number of fishing days in a year, number of fishing gears used and total investment than the other two categories.
- ItemTechnological changes among the traditional fishermen(Society of Fisheries Technologists (India), Cochin, 1993) Mohan, B.; Balasubramaniam, S.; Kandoran, M.K.; Thomas, M.The present study was conducted to determine the technological changes and impact perception among the fishermen regarding the recommended technological practices. The extent of technological changes in the practices, viz use of cheaper wood materials for construction of fishing crafts and the use of synthetic fishing net materials were almost complete. The use of chemical wood preservatives was not adopted by any fishermen. The technological change with regard to the use of ice onboard country crafts was 1.61%. The studies revealed that experienced fishermen had low adoption scores. The low technological gap scores had significant relationship with higher investment and maintenance costs of crafts and nets and crew engaged.
- ItemTechnological gaps among fishermen operating motorised and non-motorised fishing crafts(Society of Fisheries Technologists (India), Cochin, 1996) Mohan, B.; Balasubramaniam, S.; Kandoran, M.K.This study was conducted in six districts of Kerala state to monitor the technological gaps among fishermen. Among the fishermen operating motorised fishing crafts, the technological gap was wider among those operating plankbuilt crafts (34.65%). The catamaran operators had wider technological gap (45.60%) among the non-motorised categories. Out of 18 independent variables, three variables viz, the size of craft operated, number of nets used and mass media exposure were found to be key variables among fishermen operating non-motorised crafts. In the regression analysis the R super(2) values were found to be high and significant among all the categories. The fishing craft-gear combinations used by different categories of fishermen were recorded.
- ItemTechnology development efficiency and socio personal characteristics of researchers in marine fisheries(Society of Fisheries Technologists (India), Cochin, 2009) Jeeva, J.C.; Vasanthakumar, J.; Balasubramaniam, S.; Geethalakshmi, V.This paper deals with the assessment of the technology development efficiency among the researchers in marine fisheries and identification of the influencing socio-personal characteristics. The study was conducted among 72 researchers of two premier fisheries research Institutions. The results revealed that the technology development efficiency index was 88.51 plus or minus 10.01. Among the 15 variables studied, the variables viz., communication behaviour, extent of linkages with extension and clientele systems, time utilization in research, participation in professional bodies, in-service training undergone, job satisfaction, job performance and technologies generated had positive and highly significant relationship with the technology development efficiency. The R super(2) value indicated that all the variables taken together served as cause for explaining 57.60 % of variation in the efficiency level in the technology development process. The present results establish that the technology development process is efficient in marine fisheries.
