Total allowable catch
An operational management procedure, based on fishery-dependent and fishery-independent information,
is used to determine the TAC (total allowable catch) and the amount of by-catch that may be landed by the industry annually. The catching of pelagic fish is strictly managed by Department of Agriculture, Forestry and Fisheries (DAFF), according to permit conditions, and all catches are weighed on discharge. No fish may be dumped.
Scientific analysis on raw material caught is performed every three weeks and compiled into status reports. The data collected is used to monitor catches, abundance, distribution and biology and associated environmental information.
Catch volumes are monitored and adjusted according to availability at the plant and in line with the plant’s Environmental Management Plan. On hotter days, smaller volumes are taken in for processing as temperature plays a key role in the rate at which the raw fish material loses its freshness. Representative samples of all landed fish per shift are sent to independent and approved laboratories to test and measure the quality and freshness (total volatile base nitrogen —TVBN) of the intake. A register of all TVBN analyses is logged and provided to the City of Cape Town as per the Atmospheric Emission Licence Requirements.
