4128 SPECIES IDENTIFICATION AND MEASUREMENT Procedure Published / External 8543 Grand Isle 1988 Data Set Completed Penaeid shrimp were measured to the nearest millimeter total length (TL). ‘Other Invertebrates’ (non-penaeid shrimp, crabs, etc.) were measured and placed in 5 mm TL or carapace width (CW) intervals. Fish were measured and recorded in 10 mm TL size intervals. Fish were measured after being placed flat on its side with the mouth closed. TL in fish was distance from snout to tip of longest caudal fin ray. TL in penaeids was measured from tip of rostrum to tip of telson. If rostrum was broken, TL was not measured. Carapace width (CW) of crabs was measured across widest part of carapace (from tip to tip of lateral spines, if present). If lateral spines were broken, CW was not measured. Hermit crabs were not measured. Midpoint of size range represents midpoint of interval, not mean of actual measurements. Counts must be divided by 2.6 to determine abundance/m2.
