This exploitation causes a decline in fishing resources, generating negative impacts on the environment, and especially on marine benthic populations, focus of the capture of vessels that perform bottom trawling such as shrimp fishing. The incidental capture of species that are not the target of the fishery, called bycatch or bycatch, represents a threat to biodiversity worldwide. The objective of this work was to describe the population structure in size and body mass and the relative growth of crabs of the genus Calappa captured as bycatch in the industrial fishery of the pink shrimp Farfantepenaeus subtilis (Pérez-Farfante, 1967) on the Amazon Continental Shelf (PCA).). The collections were carried out bimonthly from July/2015 to April/2017, covering the rainy (March to June) and dry (July to October) periods. We identified 22 fishing grounds with capture of calapids, with 336 crabs being captured in total, varying between two species: Calappa sulcata and Calappa ocellata, with a higher occurrence of the former (77%) throughout the PCA, in muddy substrate and gravel. The sex ratio differed between species [C. sulcata was 1.11 (F:M) and C. ocellata 1.68 (F:M)]. This is the first study with description of size and body mass for populations of Calappidae in the Amazonian coastal zone.
