“…Similarly in the district diagnostic report of Thiruvallur district, it is reported that major land holding in this district is owned by others rather than by SC and ST people [35]. In West Bengal also the involvement of SC/ST communities in P. vannamei culture was found to be low but it was reasoned out that it might be due to poor financial resources as well as lack of awareness about beneficial aspects of P. vannamei culture [13].…”

Studies on socioeconomic, communication media usage, occupational, and sociopsychological attributes of farmers are prerequisite for planning, designing, and successful implementation of sustainable management strategies of a sector which is true for Penaeus vannamei shrimp farming also. The state of Andhra Pradesh in India ranks first in shrimp farming. However, Tamil Nadu state has a lot of potential and is slowly catching with third position, so the baseline profile of shrimp farmers of Tamil Nadu was collected through interviews with 316 shrimp farmers in Nagapattinam, Mayiladuthurai, Thanjavur, and Thiruvallur districts. Most shrimp farmers were men of middle-age, with experience ranging from 1 to 5 years with secondary school to graduate level education. About 89.36% of shrimp farmers had taken loans for the purpose of shrimp farming whereas 78.16% were depending on income from shrimp farming as a repayment source. The benefit–cost ratio of shrimp farming was 2.2 indicating profitability so 79.37% of them were able to save money. However, for 86.53% this was a major expenditure too indicating its vital role in their life. For acquiring information for shrimp farming, 40% relied on friends and 24% relied on fellow farmers. Shrimp farmers were well-versed with the present-era mass-media and through smartphones they acquired information from apps like YouTube. Innovation proneness, scientific orientation, and economic motivation were found to be high in about 30% of farmers. Proper planning is essential for sustainable shrimp farming and sustaining the socioeconomic benefits. The studied attributes play an important role in formulation, designing, and successful implementation of sustainable shrimp farming.

“…In case of production, maximum increasing trend was observed in the year 2015-16 followed by 2014-15 and 2013-14. However, a huge decline in production was observed in the year 2008-09 which might be due to uncertainty in the profitability of shrimp farming due to disease outbreak (Animesh and Biswarup, 2020), shift of farming practices from Tiger shrimp to newly introduced Pacific white shrimp during the year 2009 and lack of technique know-how of the farmers about the new candidate species. Conversely, later years the production and productivity were picked up gradually in West Bengal as well as India (Maity et al, 2020) due to standardisation of culture technology and knowledge acquired by the farmers on improved culture techniques of grow out system.…”

“…During period I, growth rate of area (-6.38 per cent) was negatively significant (p<0.05) while production (14.55 per cent) and productivity (23.12 per cent) showed positive growth rate. The positive growth in production and productivity might have occurred due to increase of awareness among the farmers about profitability in shrimp culture than crop farming and hence lot of agriculture lands were converted into shrimp farms during this period (Animesh and Biswarup, 2020). In Period II, growth rate of production was negatively declined (-57.54 per cent) whereas the area (5.54 per cent) and productivity (60.05 per cent) showed positive growth rate.…”

“…Ghoshal et al 2019 reported that farmers were attracted to semi intensive vannamei shrimp farming due to high yield, profitability and less pathogenic infection compared to tiger shrimp which ultimately led to high productivity in overall period of study. Nevertheless, the negative productivity effect in sub-periods might be due to adverse change in weather conditions, technological changes, poor technical knowledge due to lack of training programmes, poor and sudden viral, culture practices, seed availability and fungal disease outbreak, etc., especially while culturing the tiger shrimp as described by Animesh and Biswarup (2020).…”

Growth trends and decomposition analysis of area, production and productivity of shrimp in the state of West Bengal were carried out for a period of 16 years from 2005-2006 to 2020-21 by splitting the production data into two sub-periods i.e. period I 2005-06 to 2012-13 and period II 2013-14 to 2020-21. The growth rates were calculated using exponential function while the instability in the production was worked out using coefficient of variation (CV) and Cuddy Della Valle's Instability Index (CDVI). The change in output in terms of relative contribution of area and yield was estimated by using Minhas decomposition model. During the first sub period, the compound growth rate for the area (-6.38) of shrimp culture was found to be significantly negative (p<0.05) while production (14.55 per cent) and productivity (23.12 per cent) were positively significant. Whereas during second sub period, the growth rate of shrimp production (-57.54 per cent) was negative while area (5.54 per cent) and productivity (60.05 per cent) were insignificantly positive. However, the study revealed that the overall compound growth rate of area (1.52 per cent) and production (5.94 per cent) of shrimp in West Bengal for the entire study period from 2005-06 to 2020-21 were found positively insignificant. The maximum growth in productivity was observed during the sub period II (60.05%) followed by sub period I (23.12 per cent). The instability indices i.e. CV and CDVI were found low during all the periods in the case of area. Goodness of fit under cubic model proved as best fit among the parametric models fitted to the area, production and productivity of shrimp culture in the state of West Bengal. The area effect was found to be 100.31 per cent, whereas yield and interaction effect were 1.72 per cent and (-) 0.94 per cent respectively in the study period. Finally, the analysis emphasized that the decomposition analysis and area effect played key role in making differentiation in the shrimp production of West Bengal.
