Description The economic assessment on juvenile landings of four dominant marine catfishes at New

Ferry Wharf (NFW) landing centre, Mumbai, Northwest coast of India was carried out during January

to December, 2013. The dominant catfishes viz. Nemapteryx caelata (19.7 %), Plicofollis dussumieri

(21.5 %), P. tenuispinis (24.8 %) and Osteogeneiosus militaris (27.5 %) together contributing 93%

of total marine catfish landings of the state. Among four species, the juvenile landings of N. caelata

contribute maximum (93.17 %) followed by P. dussumieri (57.14 %), O. militaris (36.11 %) and P.

tenuispinis (21.43 %) with the maximum landing during November to March . The bioeconomic

model reveals that if juveniles are allowed to grow up to length at first maturity (Lm); an estimated

total annual economic gain will be Rs. 13.15 crores with an estimated biomass gain of 1222 t per

annum. The estimated total annual biomass is increased by 2.07 times with an increase in additional

revenue by 3.7 times would have been realised. The results of present study suggest that sustainable

harvest of these resources would have been yielded maximum economic return to the fishers. With

the help of stakeholders participatory approach, management measures such as strict mesh size

regulation, effort restriction on bottom trawl up to 50 m depth and awareness campign on catching

juveniles and adult in particular to the oral incubated male ariids, would have been implemented

during November to March to avoid growth overfishing.
