Longlining is an important fishing method targeting sharks, tuna, seer fish etc. Fishing line is tied to high carbon steel hook using stainless steel snood wire in order to avoid large carnivorous fishes from biting off the hook. Corrosion is a major problem with hooks and often the hook fails at the eye region where the line is attached to the hoo...

Corrosion of fishing hooks is a major problem faced by hook and line fishing industry. This communication presents the results of a study taken up to asses the corrosion resistance of round bent, flatted hook no. 7 with two different surface coatings; viz., tinned and blued. The hooks were exposed to 300 h of salt spray as per ASTM B117. The tinned...

Yarns of 37 different sizes ranging from 0.08 to 3.0 mm diameter were found to be in use for fishing purposes, in South India. The physical and mechanical properties viz., linear density, runnage and the tensile break-load and elongation of nylon monofilament yarns were assessed. Of the 37 diameters tested, BIS (Bureau of Indian Standards) standard...

Very few studies have been conducted to analyse physical and mechanical properties of fishing hooks. The present work is an account of a study carried out on five major brands of number seven round bent fishing hooks available in India, which are used to harvest tuna and medium sized fish resources. We have selected three imported and two indigenou...

Fishing hooks are among the simplest and the oldest of fishing devices. Due attention has not been given in the study of hooks and what ever work that are made have now become out dated due to emergence of new models, materials and technologies. There are no well-defined standard methods for classifying fishing hook. This communication reviews the...
