Growth of black ark from tagging/recapture experiments in La Paz Bay, BCS, Mexico
Esteban Fernando Félix Pico y Mauricio Ramírez Rodríguez
Growth of the black ark Anadara tuberculosa (Sowerby, 1833) (Bivalvia: Arcidae) was estimated in ElMogote and El Conchalito mangrove systems in La Paz Bay, Baja California Sur, Mexico. The principalaim was to compare individual von Bertalanffy growth parameters estimated through tagging techniques.Ark individuals were tagged with serial numbers painted or printed (Dymo). A total of 760 arks weretagged at El Mogote and 272 at El Conchalito. Quarterly searches of tagged individuals were made fromOctober 2010 to January 2012. Three other samples were obtained in 2013, 2014 and 2015. The Gullandand Holt plot method was applied to analyze growth increment data, and to estimate L8 and K. For ElMogote black arks, 95 individuals were recaptured with sizes between 44.6 and 90.8 mm. The parametervalues were L8=90.0 and K=0.189. For El Conchalito, with 41 recaptured between 38.2 and 80.6 mm,the parameters were L8=83.0, K=0.171. The growth rate differences between both populations are likelydue to environmental factors and nutritional deficiency.
