Allometry, condition index and secondary production in bivalve Barbatia decussata on rocky intertidal shores in the Northern Persian Gulf, Iran.

Biological parameters including allometry, condition index and secondary production were estimated for Barbatia decussata on rocky intertidal shores in the northern Persian Gulf (Iran) between August 2011 to September 2012. Relationship between shell dimensions (length, height, width, hinge) as well as relationship between shell length and weight (total wet weight, tissue wet weight, tissue dry weight, tissue ash free dry weight, shell dry weight, shell ash free dry weight) were estimated with b (equilibrium constant) values ranging from 3.023 to 3.
