Abstract

The present investigation is about the economic analysis of the hook and line fishery along the coast of Kombuthurai, Thoothukudi district of Tamil Nadu. Inferences from the study indicated that that hook number 5, 6 and 7 were found ideal for commercial exploitation of Carangids, Grouper, Barracuda and Needlefish in angling by wielding fresh condition live bait. Using the artificial lure number 3.5, 4.0 and 4.5 applied in trolling line, the most dominant catch was seer fish (80%) and least in sailfish (8%). Significantly the study reports that the highest gross revenue ₹42060/trip was made in trolling line than that of the handline of ₹26400/trip ascribed by targeted of high market value species. The trolling line crew share per person was twice over than the handline fishing (₹3821/trip). Instead of unorthodox eye estimation of fish weight, a novel approach of weight based fish sale (for low to high market value species) was observed in Kombuthurai fishing village and this practiced also espoused by a neighbor fishing village.

Highlights

Marine fishers use different type of crafts and gears for harvesting fish and its efficiency is significantly important for better income
The practices of hook and line are fascinating amid fishers; it excels in capturing high market value species namely the seer fish, mackerel, tuna, elasmobranchs etc.[4,26,27]
Operational details The experimental handline and trolling line were operated by 15 m (OAL) FRP boat each fitted with 9.9 Hp Out Board Motor (OBM) (Table 2)

Summary

Introduction

Marine fishers use different type of crafts (boats) and gears (nets) for harvesting fish and its efficiency is significantly important for better income. The hook and line were deemed as important, so studies on their performances were done for better understanding[5,20,11,27]. The handline, pole and line, trolling line, jigging line and longline are prominent which are in practice throughout coastal region of India. It was recognized as eco-friendly fishing gear than other kinds of fishing practices but it catches the non-target species[3,19,17,7]. It is interesting to note that they perform even in the rocky area and uneven bottom places as well[10]
