Abstract:
Character string:
The CAGES program (Comparative Assessment of Gulf Estuarine Systems) is designed to examine the differences
between estuarine ecosystems and investigate why some are more productive than others. The program focuses
on estuarine areas important to commercial fisheries and includes data on commercial finfish and
invertebrate species, as well as other species commonly captured in trawl sampling. This Mississippi dataset
is a subset of the CAGES Relational Database which is a compilation of fishery-independent data contributed
by natural resource agencies of the Gulf States (Texas, Louisiana, Mississippi, Alabama, and Florida). This
data set includes data from trawls collected by the Mississippi Department of Marine Resources and the
University of Southern Mississippi's Gulf Coast Research Laboratory (MDMR/GCRL), as well as associated
hydrographic data. Trawl data were used to calculate CPUE (catch per unit effort) at each station for the
years 1973 through 2005.
Purpose:
Character string:
The purpose of CAGES is to compile the fishery independent data from five Gulf States into a database to more
easily compare the fisheries across the US Gulf of Mexico coast. This dataset includes data collected from
Mississippi only. The CAGES database is intended for scientific research only.

Description:
Character string:
The Mississippi Department of Marine Resources and the University of Southern Mississippis Gulf Coast
Research Laboratory (MDMR/GCRL) conducted monthly resource assessments at designated stations in the
Mississippi Sound. MDMR/GCRL selected these few sites as being representative of their areas nekton
based on past surveys. The standard trawl used for fisheries-independent sampling was a 4.9-m
(16-ft) flat otter trawl with 3.8-cm (1.5-in) stretched mesh webbing of nylon multifilament twine.
Environmental data were collected at each site prior to the trawl tow. Surface and bottom water
temperature and salinity were recorded along with water depth before each tow. The MDMR/GCRL trawl
also was fitted with a 6-mm (1/4-in) bar mesh liner. The trawl was spread by 0.9 m long by 0.5 m
tall (36 x 18 in) plank board trawl doors protected along their rims by iron plate. Tow line length
was determined by a 6:1 scope with water depth. Trawls were towed for 10 minutes at about 3.7 kph
(2.4 mph) from a 6.4-m (21-ft) research boat. Abundance data were not collected for the following
species until 1985: Anchoa mitchilli, Bairdiella chrysoura, Lagodon rhomboides, Paralichthys
lethostigma, Pogonias cromis, Sciaenops ocellatus, and Symphurus plagiusa. All specimens caught in a
trawl were identified, counted, and recorded. Standard length (mm) and weights (g) of up to 50
specimens of each species, including the minimum and maximum sizes, were measured and recorded for
commercial species only. For non-commercial species only minimum and maximum standard lengths were
recorded (Anderson 2009).
Process step:
LI_ProcessStep:
Description:
Character string:
Catch data in trawls were converted to numbers caught per hectare (#/ha) using the tow times and
calculated conversion factors. The conversion factor was calculated based on an assumed 80% spread
of the width of the trawl webbing along the headrope (defined here as the headrope length) and the
estimated distance towed in one minute calculated from reported tow times. The conversion factor is
equal to the time needed (in minutes) for the trawl to cover one hectare. To calculate the CPUE the
following formula was used: Conversion factor / Tow duration (min) X Number caught = #/ha. The
conversion factor for Mississippi was calculated to be 41.56.
