Abstract

Sisal hemp (Agave sisalana) leaves were harvested and processed using the beating and decomposition methods. The fibres obtained were washed, dried and finally spurned in to cordage of about 4mm diameter 39 pieces of ropes, each measuring 2 meters were altogether spurned. 30 pieces of these ropes were immersed in water for a period of 24 weeks, 6 were placed in a shaded and airily place and 3 were used for the head and footling of gillnet, sinker line of cast net and the main line of long line. Every other week, the ropes in water and air were tested for its breaking strength using an improved 50kg spring balance. At the end of the experiment, it was found the immersed ropes maintained a tensile strength of over 50kg/F for the first 18 weeks, thereafter; there was a gradual weekly reduction in the strength until the 23rd week when the tensile strength was less than 1kg/F. The cost benefit analysis showed that about 5,3146 tons processed fibers could be obtained fro 1ha. capable of being spenced in to 528300m of 4mm diameter cordage. This paper finally recommended the growth of sisal hemp plants by fisher folks so that there will be constant stock for intermittent harvesting for rope spurning
