Farm Size and Aquaculture Productivity Relationship

摘要

Due to the influence of many independent variables, productivity being a dependent variable, exhibits wide variation In the present communication the relationship between farm size and aquaculture productivity has been reported. Data from 79 representative farms collected from July 1998 to July 1999 at the Eluru and Kaikalur blocks of the Kolleru lake area have been considered. The size of faims ranges between 0..8 to 60 ha whereas productivity ranges between 10 to 14 t ha~(-1) yr~(-1). Positive correlation between carp productivity and area of the farms has been found (r = 0.52). The coefficient of determination
