Abstract

Sport fishing is a popular activity among people who want to have fun. Knowledge of the use of fishing tools are also different for each angler such as the selection of appropriate hooks in catch-and-release (C&R) or catch-and-keep (C&K) activities. Hook type can affect physical damage and catch per unit effort (CPUE) while fishing. However, limited information on hook-related damages. The objective of this study is to evaluate the effect of hook size and types on hooking damage, CPUE, survival rate, and species composition of fish in the UPM Bintulu Campus recreational pond. The fishing tools used in this study are rods, lines, reels and two varied sizes of hooks with natural baits on barbed and barbless hook. The species identification, size of the fish, injury level and survival rate of the fish were assessed during the study period. The results indicated the injury level in non-critical areas was 73.2% is higher compared to critical 26.7%. These comprised a considerable number of injuries level at the outer lip (barbed hook 5), upper and lower jaw (barbless hook 5), inner gills (barbless hook 5 and barbed hook 8) and stomach (barbed hook 5). CPUE shows the total catches of Oreochromis mossambicus are the highest by using hook size five compared to size eight. The survival rate was significantly higher for both barbless hook sizes 5 and 8 as compared to barbed hook, respectively. Therefore, hook size and hook type selections were important factors to be highlighted in strategizing the implementation of C&R in Malaysia towards the sustainable recreational fisheries industry. Keywords: Recreational fishing, effectiveness, injury, barbed hook, and barbless hook.
