Abstract
A total of 66 fish kills were reported to the Regional Fisheries Boards in 1986 and 122 in 1987. Effluents from agriculture and agriculture-based industries accounted for 56 of the kills in 1986 and 95 in 1987. When the two periods, 1969-74 and 1980-87 are compared, it can be seen that the numbers caused by sewage and industrial wastes have not changed significantly, but the damage from agriculture has risen at an alarming rate. The fact that problems from sewage and industry remained at a low level in the period, in spite of increasing urbanisation, suggests that measures to combat these sources of pollution have had some effect. Analysis of the fish kills shows clearly that the most urgent problem is to discover how silage effluent can be controlled.
