The linear regression line was engaged for the analysis of inland fish and fish seed production data with the duration of 11 years. The figure 2 shows that there is no relationship between fish seed production and inland fish production of Tamil Nadu (R² = 0.001). Figure 3 shows that there is irregular growth rate during the 11 years (R² = 0.006). A strong significant relationship (R² = 0.673) between inland fish production and years, which is represented by Figure 1.  It indicates the fact that increasing trend of inland fish production of Tamil Nadu.
