Ch. Kirchner et al., Introducing size limits as a management tool for the recreational line fishery of silver kob, Argyrosomus inodorus (Griffiths and Heemstra), in Namibian waters, FISH MA EC, 8(3), 2001, pp. 227-237
Individual silver kob Argyrosomas inodorus (Griffiths and Heemstra) first m
ature at just over 1 yr of age and the median age at maturity is approximat
ely 1.5 yr. Spawning of silver kob was observed in the southern and central
region of the stock's range, but little spawning activity was found in sil
ver kob sampled from the northern region. The spawning period is protracted
over 6 months (October-March), which coincides with warmer water temperatu
res (> 15 degreesC) and the occurrence of large-sized spawning silver kob i
n the southern and central part of Namibia. Implementing a minimum size lim
it for the silver kob fishery is not recommended as it will have serious ec
onomic implications for the coastal communities. The protection of the spaw
ning areas, Meob Bay and Sandwich, should be continued and a strict bag lim
it on large-sized silver kob is recommended for the Namibian silver kob rec
reational fishery.
