dc.description.abstractGrowing concern about the quantity and diversity of by-catch species caught in the bottom trawling nets of crustacean fisheries led us to compare the quantity of by-catch recorded in Chilean and Costa Rican deep-water shrimp fisheries by year, latitude, and bathymetry. We analyzed catches from 2143 trawl hauls between 2004 and 2009 from the fisheries of the northern nylon shrimp,Heterocarpus vicarius, and the kolibri shrimp,Solenocera agassizii, off Costa Rica and the Chilean nylon shrimp, Heterocarpus reedi, off Chile. A catch index was estimated to determine the quantity of by-catch retained for each kilogram of shrimp. The by-catch associated with the shrimp fisheries of Costa Rica and Chile was mainly fishes and crustaceans; by-catch species diversity was considerably higher in Costa Rica compared to that of Chile. In Chile, catches of H. reediand by-catch were greater in the central and southern zone, whereas in Costa Rica, catches of shrimp (H. vicarius, S. agassizii) and by-catch were higher in the central zone. In terms of bathymetry, the largest catches of shrimp and by-catch came from the deep stratum (between 251 and 400 m) for both countries; the by-catch was noticeably larger in this stratum in Costa Rica. The catch index revealed that for every 1 kg of shrimp caught in Costa Rica, 5.7 kg of by-catch were caught; in Chile, this ratio was 1.1:1. However, the projected global by-catch was considerably higher for the fishery forH. reedithan for that ofH. vicarius,which is related to the landed volumes of the target species in Costa Rica and Chile. The encouraging results in the H. reedi-fishery concerning technical measures to reduce by-catch and discards rates should be also considered for Central American deep-water shrimp fisheries.es_ES
dc.description.sponsorshipThe authors (PA and JCO) thank the Fondo de Investigación Pesquera (FIP) for funding the fishery assessment projects carried out off the central coast of Chile and for the availability of the data bases used to develop the present project. The researchers from Costa Rica (ISW, VNM and FVR) are thankful to the company The Rainbow Jewels, S.A., Puntarenas, for their ongoing support for monitoring the deepwater resources of Pacific Costa Rica. Likewise, thanks a lot to the captains (Rigo and Esteban: “Mecate”), crews of the shrimp trawlers ONUVA and SULTANA, and all the students who helped us with the collection and handling of the samples. Financial support was made available from the German company Ristic AG, Oberferrieden, the Costa Rican company The Rainbow Jewels S.A., Puntarenas, and the University of Costa Rica (projects V.I. No. 111-A4-508, V.I. No. 808-A9-536 and V.I. No. 808-A9-537). Additional funding was provided by the “Program University – Enterprise for Sustainable Development” (PUEDES) of the Council of Central American Universities (CSUCA), the German Society for Technical Cooperation (GTZ) and the University of Kassel, Germany. Furthermore, we are grateful for the logistic support provided by the Center of Marine Research and Limnology (CIMAR) and the School of Biology, University of Costa Rica. We are grateful to Ing. Álvaro De Caso for his collaboration with the statistical analysis of the fishery data. Danielle Barriga and Tayler Clarke revised and improved the English, which is greatly appreciated. Finally, we are thankful to Raquel Romero-Emilia, who helped us to prepare the final version of the figures.es_ES
