Abstract
Family Serranidae includes important commercial species. Twelve Serranid species inhabit in the
surrounding waters of Turkey and 3 of them (Painted comber Serranus scriba, Dusky
grouper Epinephelus marginatus and White grouper Epinephelus aeneus) are of commercial
importance according to the fishery statistics of Turkey. Total capture production of these species
together constitutes less than 1% of the total capture production of Turkey. While angling,
spearfishing, and longlining are the main catching methods for groupers, painted comber is generally
captured by demersal trawls, gill nets, longlines and handlines. Minimum landing size (MLS) was
assigned to be 45 cm total length for groupers and no MLS was determined for painted comber.
According to Turkish fishery statistics, white grouper has a production amount of 191.5 tons,
followed by painted comber (44.6 tons) and dusky grouper (13.4 tons) in 2014. Production amounts
of these 3 species in 2014 are below the production amounts of 2005 displaying sudden declines in
this period. The probable reasons of this decrease are considered to be illegal fishing, uncontrolled
landings, inadequate controlling during marketing and unconscious fishing. Although their high
commercial and ecological importance, there are very limited studies on the biology, ecology and
fishing of these species in Turkey. On the other side, inadequate nomenclature of the Serranids in the
Turkish official documents constitutes a big deficiency. First step for a sustainable fishing
management for these fishes is to make proper naming of the groupers according to scientific
nomenclature and improve our knowledge on the biology of the species.
