Improved Fishbite Armor for Deep-Sea Mooring Lines.

Abstract

An improved procedure for the collection and correlation of deep-sea lines fishbite data with geographical location and ambient conditions is described. Triggerfish and a small shark, Isistius brasiliensis, are added to the list of suspected biters. The first known instance of fishbite on a deep-sea mooring line at a station moored in the Indian Ocean is recorded. A screening test procedure for identification of thermoplastics which have a potential for use in protecting mooring lines against fishbite has been developed. Results of tests made on materials which are currently in production indicate that suitable materials may be found among the fluoropolymers, ABS resins, cellulose esters, acrylic/PVC alloys, polyterephthallates, and nylons. Five specific resins are recommended for trial on experimental deep-sea mooring lines. (Author)
