38. Decapod abundance and species richness in the bycatch of Xiphopenaeus kroyeri (Heller, 1862) fishery, Santa Catarina, southern Brazil
Abstract We aimed to analyze the crustacean bycatch from the Xiphopenaeus kroyeri fishery in the Santa Catarina State and compare the bycatch’s biomass to that of the target species. Shrimp and environmental factors were sampled monthly from July 2010 through June 2011. For each crustacean species, we calculated the number of individuals, the relative abun

39. Assessment of the nitrification process in a culture of pacific white shrimp, using artificial substrate and bacterial inoculum in a biofloc technology system (BFT)
RESUMO: Litopenaeus vannamei é o camarão marinho mais cultivado em todos os tipos de sistemas, incluindo o Sistema de Tecnologia de Bioflocos (BFT). Os bioflocos são formados por microorganismos, entre estes, bactérias autotróficas que são responsáveis pelo processo de nitrificação. Este estudo teve como objetivo identificar e promover o desenvolvi

41. Record of the rare Caribbean mud eel, Pythonichthys sanguineus (Heterenchelyidae, Anguilliformes), in the region of the Amazon Reef
RESUMO Heterenchelídeos passam a maior parte do tempo enterrados no substrato e raramente são vistos, não representando recursos pesqueiros importantes. Essas enguias são caracterizadas por seus olhos muito reduzidos e cobertos por pele semi-transparente, ausência de nadadeiras peitorais ou linha lateral, e ausência de poros na cabeça ou no corpo.

42. New records of the shrimp Periclimenes crinoidalis Chace, 1969 (Decapoda: Palaemonidae) and its crinoid host Nemaster grandis A.H. Clark, 1909 (Echinodermata: Crinoidea) in the Caribbean Sea
Abstract During exploratory trips conducted between August and December 2016, six shrimps, found in association with the crinoid Nemaster grandis A.H. Clark, 1909, ere collected in Chichiriviche de la Costa, Vargas State (Venezuela). A photographic record of the crinoids and the shrimps was conducted in situ. Shrimps were preserved in ethyl alcohol 90% and c

43. Morphometric variation in pink shrimp populations at Rio de Janeiro coast (SE Brazil): are they really similar in closer areas?
Abstract:Farfantepenaeus brasiliensis and F. paulensis are the most exploited shrimps of SE-S Brazilian coast. Our aim was to verify if adjacent nursery areas with different environmental condition (Sepetiba and Guanabara bays, SE Brazil) influence on shrimp populations (eg, CPUE) and body shapes. Samplings were carried out during 12 months in those bays ca.

45. Extraction and purification of astaxanthin from shrimp shells and the effects of different treatments on its content
Abstract In this study, the extraction process and purification technology of astaxanthin from shrimp shells were established, and the effects of different treatments on the content of astaxanthin were studied. The determination results of astaxanthin in various shrimp/crab shells showed that the astaxanthin content in the Procambarus clarkia shell reached 2

46. La efectividad de una ley de protección al servicio de la conservación de un recurso marino: El ejemplo del camarón fantasma Callichirus major (Decapoda, Callianassidae) de la costa de Brasil
ABSTRACT Studies on mortality due to fishing based on isolating the effect caused by catches are scarce. The present study analyzed this aspect using the ghost shrimp Callichirus major (Say, 1818) as a biological model, which is heavily harvested along the Brazilian coast. For that purpose, density of burrows and population structure of C. major was examined

47. Richness and large-scale distribution of marine benthic caridean shrimps (Decapoda: Caridea) from the Eastern Tropical Pacific
Abstract Based on an updated checklist of the benthic caridean shrimp fauna of the Eastern Tropical Pacific (ETP), we analyzed their large-scale species richness distribution patterns using a grid approximation. Caridean fauna is composed of 183 species belonging to 67 genera and 18 families. Alpheidae, Palaemonidae and Thoridae contributed largely to specie

Abstract We determined the infestation rate of Probopyrus sp. in populations of Palaemon pandaliformis (Stimpson, 1871) and P. northropi (Rankin, 1898) in the Ubatumirim River, localized in a mangrove ecosystem on Ubatumirim Beach, northern coast of the state of São Paulo, Brazil. Samplings were carried out monthly from April 2003 to March 2004. Monthly pre
