The Behavioral Basis For Blue Crab Recruitment In Mid-Atlantic Estuaries

THE BLUE CRAB IN MID - ATLANTIC BIGHT ESTUARIES : A PROPOSED RECRUITMENT MODEL Project Directors

Virtual population analysis, recruitment pattern and cohort analysis of blue swimming crab, Portunus segnis (Forskal, 1775) in coastal waters of Persian Gulf and Gulf of Oman, Iran

This study was conducted to determine the virtual population analysis, recruitment pattern and cohort analysis of blue swimming crab (Portunus segnis) in coastal waters of the Persian Gulf and the Oman Sea (Hormozgan province). Sampling was carried out monthly by bottom trawl from May 2010 to October 2011. Results of Thompson and Bell prediction analysis showed that the maximum sustainable yiel...

Vertical movement of mud crab megalopae (Scylla serrata) in response to light: Doing it differently down under

Selective tidal-streaming is a model frequently used to explain how planktonic larvae invade estuaries. The ability of larvae to move vertically in the water column to selectively ride favourable currents and maintain ground gained is critical to this process. The mud crab (Scylla serrata) is a widely distributed, commercially and recreationally important portunid crab but little is known about...

High Connectivity among Blue Crab (Callinectes sapidus) Populations in the Western South Atlantic

Population connectivity in the blue crab Callinectes sapidus was evaluated along 740 km of the Western South Atlantic coast. Blue crabs are the most exploited portunid in Brazil. Despite their economic importance, few studies report their ecology or population structure. Here we sampled four estuarine areas in southern Brazil during winter 2013 and summer 2014 in order to evaluate diversity, ge...

Mitochondrial DNA Variation Reveals a Sharp Genetic Break within the Distribution of the Blue Land Crab Cardisoma guanhumi in the Western Central Atlantic.

The blue land crab Cardisoma guanhumi is widely distributed throughout tropical and subtropical estuarine regions in the Western Central Atlantic (WCA). Patterns of population genetic structure and historical demographics of the species were assessed by mtDNA control region sequence analysis to examine the connectivity among five populations (n = 97) within the region for future conservation st...
