Abstract
Recreational fishing by angling is practised worldwide which is gaining importance in India as well. Circle hooks are getting more popular as it shows less injury with enhanced post-release survival, which promote catch and release as well as conservation. In the present study, circle and ‘J’ hooks were compared for hooking pattern, extent of injury and post-release survival in Genetically Improved Farmed Tilapia (GIFT) in recreational fishing. Results depicted that overall hooking rate was lower for circle hooks (29%) than ‘J’ hooks (31%). Occurrence of lip hooking was more with circle hooks (73.6%) than ‘J’ hooks (58.8%), whereas jaw hooking was comparatively low in case of circle hooks than ‘J’ hooks. Circle hooks showed no throat hooking whereas ‘J’ hooks recorded 5.88% for the same. Foul hooking was not observed in case of both hook types. In the present study, with ‘J’ hooks, 52.9% of fishes showed no bleeding, slight and moderate bleeding was found in 17.6% fishes, whereas 11.7% had severe bleeding. For circle hooks, the corresponding values were 73.6, 21.05, 5.26 and 0%. There was 100% survival for the fishes upto 72 h post-release in both cases.
