Abstract:

Callinectes megalopae were collected from the water column in Galveston, TX and Freeport, TX from August 2013 to August 2015 and identified by 16S mitochondrial sequences. Most of the megalopae could be assigned to C. sapidus (62%), C. similis (36%) C. rathbunae (1.5%), or C. danae (0.12%), while 5 (0.8 %) were ambiguously grouped with both C. similis and C. danae. This dataset reports Callinectes abundances (as mean per tow) for C. rathbunae, C. danae, C. sapidus, and C. similis.

Purpose:

Investigate potential for misidentification and differences in Callinectes species composition in monthly megalopal sampling events.

Data Parameters and Units:

Collection, Location, Month, Day, Year, Total abundance, Callinectes rathbunae abundance, Callinectes danae abundance, Callinectes sapidus abundance, Callinectes similis abundance; Mean megalopae per tow of a plankton net to define abundance. Sampling location Latitude (decimal degrees) Longitude (decimal degrees) Galveston 29.2507 -94.86295 Freeport 28.9355 -95.3044

Methods:

Megalopae were collected from the water column using a 253 µm plankton net towed in ~1 m of water in the surf zone parallel to shore between 05:00 and 09:00. Species were identified by 16s mitochondrial sequences (GRIIDC dataset R2.x214.000:0006).
