Problems facing the deep-sea fishing industry in Sri Lanka

Fishing in Sri Lanka has been carried on largely with the use of traditional methods and in recent years there has been a marked increase in the use of mechanized craft for fishing. Although some effort has been made in the sphere of deep-sea fishing both by trawlers and long line tuna boats, such efforts have not made a significant contribution towards improving the industry. The progress of deep-sea fishing in Sri Lanka has been hindered due to a number of reasons described by the author.

Role of the state and financial institutions in financing the fishing industry

The experience of the Government in the recovery of loans for 28 foot mechanized vessels has been unsatisfactory. The author examines the various aspects which have contributed to this situation, and considers arrangements for financing purchase of such vessels. The risks associated with the investment in 38 foot vessels are high, and it seems that the reluctance of private investors to make the required contribution from personal funds is a result of fear of the unknown. Current incentives provided by the Government to the private sector for the purchase of 38 foot vessels are considered to be adequate.

A survey of process hygiene in the Sri Lankan prawn industry. 1. Hygiene status of raw materials and products

A survey of processing hygiene in the Sri Lankan prawn industry has shown that the incoming raw material has extremely high bacterial loadings; about 50% of samples analysed had a total count in excess of 10,000,000/g. Although beheading reduces the count, ineffective temperature control during processing means that the final total count of raw, shell-on, P.U.D. and P.A.D. prawns, as well as cooked prawns, is in excess of 1,000,000/g. - the maximum level specified by many importing countries.

Of 262 personnel tested, 137 (52%) were found to be positive for Staphylococcus aureus. Among individual companies the prevalence of S. aureus ranged from 92% (Company No. 1) to 22% (Company No. 2). Although five companies provided a sanitiser hand-dip, this was found to be ineffective for the control of S. aureus. Provision of hand-washing facilities, of protective clothing and of toilet facilities was found to be inadequate for an export food industry.

A survey of process hygiene in the Sri Lankan prawn industry. 3. Critical control points

Of fifteen processing plants surveyed in Sri Lanka, only five were found to have a prawn process which was adequately controlled. Most common process faults were: inadequate chilling of prawns after a wash in 30°C, mains water, the use of large blocks of ice to cool prawns, and high ratios of prawns to ice. There was also ample scope for cross-contamination of the processed prawns.
