Shrimp fisheries in the Gulf of Mexico
brown ( F. aztecus)
full exploited
red ( F. brasiliensis)
full exploited
pink (F. duorarum)
collapsed
white ( Farfantepenaeus setiferus) overfished
( Xiphopenaeus kroyeri)
Sequential fishery
High proportion of bycatch (1:4 to 1:12)
Closed seasons and areas to avoid &
protect growth and recruitment
overfishing
Goals of management: recover stocks,
maintain stocks over Limit Reference
Point, reduce bycatch and damage on
bottoms because trawling
full exploited
Abalone blue (Haliotis fulgens) and yellow (H. corrugata)
collapsed (with some signals of recovery in some places)
Minimum legal size, closed seasons and areas, reduction of catch
quotas
Goal of management: stock recovery. Biomass to its high production
level year to year
Shrimp
Brown (Farfantepenaeus californiensis), red (F. brevirostris), blue
(Litopenaeus stylirostris), white (L. vannamei), white (F. occidentalis),
zebra (Trachypenaeus faoea), botalón (T. pacificus), rock (Sicyonia
penicillata) and Xiphopenaeus riveti
white and blue shrimps: overfished
others: Full exploited , rock: potential
Goals of management: avoid growth and recruitment
overfishing, and protect reproductive season.
Closed seasons and areas, control fishing effort
and fishing gears, trawl prohibition within bays
Increase biomas at the end of the fishing seasons
Red urchin (Strongylocentrotus franciscanus)
overfished
Closed season, catch quota per area, minimum legal
size, number of licenses
Goal of management: reach 0.5Bo
Red snapper (Lutjanis campechanus)
Full exploited
Licenses, maintainance of catch
Goal of management: avoid reduction of
biomass below 0.5Bo
Spiny lobster (Panulirus argus)
Full exploited
Number of licences (concesions), closed season, minimum
Legal size, catching ovigerous females is prohibited
Goal of management: maintainance of spawning stock
and recruitment within the maximum stock production

Mullets (Mugil curema and M. cephalus)
overfished
Minimum legal size, closed season
(currently it was suggested an
increment zise at first capture and noincrease the size of the fleet
Goal of management: minimum legal
size must be adults whiche were
reproduced at least one time
Red snapper (Lutjanis peru)
Full exploited
fishery access through licenses
Goals of management: resources usage
under vigilance
Crab: green (Callinectes belicosus), blue (C.
arcuatus), black (C. toxotes)
Full exploited
Control of fishing effort through number of pots and
boats, minimum legal size
Goal of management: recover biomass, maintain an
fishing mortality of F=2.5 and an exploitation rate
of E=1.97 per year for all recruited ages
BENTHIC FISHERIES OF MEXICO
Mullets (Mugil curema and M. cephalus)
overfished
Minimum legal size, closed season
(currently it was suggested an increment
size at first capture and no-increase fishing
effort
Goal of management: maintain catch level
per zone
Red grouper (Epinephelus morio)
overfished
Number of licences, catch quota and minimum legal size
Three fleets, small and medium scales (Mexican), large (Cuban)
Goal of management: recover stock over Limit Reference Point
Octopus fishery (Octopus maya <70%> O. vulgaris (30%)
Full exploited
Number of licenses, minimum legal size and catch quota
Goal of management: optimize capture
low ecological impact
Queen conch (Strombus gigas) collapsed
closed since 1994 in Yucatan,
closed from 1990 to 1996 in Quintana Roo
Minimum legal size, catch quota and closed seasons
Goal of management: stock recovery
