Fish as feed inputs for aquaculture: practices, sustainability and implications

336 Fish as feed inputs for aquaculture – Practices, sustainability and implications

The majority of vessels used for foodfish anchoveta are wooden vessels (475)

(Table 7), which represent 89 percent of the total number. These vessels do not have

appropriate preservation systems on board, generally using boxes and ice. Steel vessels

(58) represent 11 percent of the total number and have RSW or CSW systems.

In 1999, the Ministry of Fishery of Peru established the maximum size of purse-

seiner nets for anchoveta and sardines in relation to vessel hold capacities (Table 8).

To guarantee the implementation of this measure, a net-size adaptation process was

stablished whereby users require an Adaptation Certificate for purse-seiner nets.
