Farm forestry was promoted in India in the late 1970s to produce fuelwood for rural consumption. The program was immensly successful in the green revolution region in the early 1980s, but farmers produced wood for markets, and not to meet local needs.

The results of a study on the fishery, biology, exploitation and mortality of hilsa shad (Hisa ilishu) are presented. The average annual landing of Hilsa ilisha for 1979 - 88 was 5710 tonnes forming 0.4% of the total landings. The major craft and gears and the contributions of different states are presented. Age at first maturity was estimated as 1.98 years. The details of spawning migrations, maturity stages and fecundity are discussed. The total mortality, natural mortality and fishing mortality coefficients were obtained as 1.71,0.704 and 0.9444 respectively.
