Several fisheries development programmes are implemented in the state for development of inland fisheries. With the implementation of schemes like Blue revolution and Pradhan Mantri Matsya Sampada Yojana (PMMSY), more numbers of stakeholders are seen to be involved as beneficiaries of schemes in fisheries sector. Present study was carried out with the objective of assessing the constraints faced by the beneficiaries in the Vidarbha region of Maharashtra. A total of 35 constraints were categorized under five heads-'Extension' (07), 'Financial' (06), 'Infrastructure' (07), 'Core Fisheries' (07) and 'Administrative' constraints' (08). Information was collected from 450 beneficiaries from 11 districts of Vidarbha region of Maharashtra. The responses were statistically analyzed using weighted average technique and Friedman test. Maximum severity score was 180 and minimum was 0. The results revealed that, overall severity of constraints among the beneficiaries was found to be medium. However, among these, financial constraints (107.89) and administrative constraints (94.05) were found to be more severe than other constraints.

Monsoon flooding is particularly damaging to farming in Assam. This paper presents the nature of flood and the results from an evaluation of the impacts of the monsoon flooding 2017 monsoon flood events on the fishery in Assam. High economic losses were incurred in the fishery sector. Fish farmers incurred direct losses in fish loss, damages in pond dykes and embankment, stock damages, etc. due to flooding and associated water inundation in ponds and fish farms. An average amount of ₹ 55,461(60 %) of loss is incurred in fish and followed by damages or losses in pond dyke or embankment, ₹ 20908 (22.64 %) in 1 acre of pond. Although total costs to the fishery were small compared with urban flood costs, they were typically large at the individual farm scale. The results presented here provide valuable insights into how flooding affects fisheries and can inform future priorities in policy development and research in flood risk management.

Its acreage and production are also increasing in day after day. This study was accomplished to examine the profitability and resource use efficiency of potato cultivation in five upazilas of Munshiganj district of Bangladesh. A total of 52 farmers were selected randomly from the study area. Data were collected through farm survey by using a suitable pre-tested questionnaire in February-March, 2016. Profitability analysis, Cobb-Douglas production function, MVP, MFC and Farm Budgeting model were used to analyze the objectives. Average gross return, gross margin and net return were found Tk. 3,47,200, Tk. 1,47,125 and Tk. 1,17,300, respectively. Benefit-cost ratio was found 1.51 and 1.74 on full cost and variable cost basis, respectively. The key production factors, i.e. human labour, land preparation, seed, fertilizer, insecticides and irrigations had significant effect on gross return of potato. Resource use efficiency analysis revealed that farmers were not efficient in using resources in potato cultivation. Human labor, land preparation, insecticide and irrigation were under-utilized and therefore increasing use of those resources could maximize the profitability. Seed and fertilizer constituted major parts of the cost of production hence optimum use of those resources could also enhance the profitability and resource use efficiency of potato cultivation in Munshiganj district.

A sample of 200 poultry-egg farmers was selected by multistage sampling technique and data were collected by using a structured questionnaire. The data were analyzed using descriptive statistics, budgetary analysis, and Stochastic Frontier Analysis techniques. The study revealed that poultry-egg production enterprise is profitable in the study area. Maximum Likelihood Estimate of coefficients of the stochastic frontier model for poultry-egg production were all positive and the parameters estimates of farm size, veterinary services, feed intake and labour were statistically significant, indicating that they contributed incrementally to the total value of poultry-egg output in the study area. Analysis of inefficiency model shows that factors influencing technical efficiency were years of experience, access to credit, cooperative membership and extension contact. Recommendations include the establishment of feed producer cooperative society, provision of adequate and timely veterinary services, and access to credit, frequent extension contacts and adult education classes for the farmers.
