A temperature atlas of the Gulf of Panama, 1955-1959

The interests of the Inter-American Tropical Tuna Commission in the hydrography and biology of the Gulf of Panama have been adequately stated in the Commission's Bulletin series (Forsbergh, 1963; Howard, 1954; Howard and Landa, 1958; Peterson, 1961; Schaefer, 1953; Schaefer and Bishop, 1958; Schaefer, Bishop and Howard, 1958). The present report deals with data collected on 10 surveys made by Tuna Commission personnel for the purpose of describing seasonal upwelling by means of a study of the temperature structure of the Gulf of Panama, and a comparison of the thermal pattern during the dry, upwelling season (January to April) with that of the rainy season (May to December). Considerations of upwelling in the Gulf have been shown to be of interest and of probable biological consequence by Schaefer (1951) and by Simpson (1959). (PDF contains 60 pages.)

Oceanographic atlas of habitats of larval tunas in the Pacific Ocean off the Azuero Peninsula, Panama

This report presents maps and statistics of summaries by season (dry and wet) of temperature, salinity, density, oxygen concentration, and oxygen saturation at six depths (0, 3, 10, 30, 50, and 100 m) in the Pacific Ocean off the Azuero Peninsula, Panama. Profiles made with a conductivity-temperature-pressure (CTD) probe on a 14-station grid from July 1989 through August 1991 provide the basis for these products. (PDF contains 37 pages.)

Temporal variation in growth of yellowfin tuna (Thunnus albacares) larvae in the Panama Bight, 1990

Tuna larvae (at flexion, postflexion, and transformation stages) were collected by dip net and light traps at night in the northwestern Panama Bight during the season of reduced upwelling (June−September) of 1990, 1991, 1992, and 1997. The larvae were identified as yellowfin tuna (Thunnus albacares) by mtDNA analysis. Ichthyoplankton data from bongo and Tucker trawl tows were used to examine the potential prey abundance in relation to the mean size-at-age and growth rates of the yellowfin tuna larvae and their otoliths. The most rapid growth rates occurred during June 1990 when plankton volumes were at their highest levels. The lowest plankton volumes coincided with the lowest growth rates and mean sizes-at-age during the August−September 1991 period. High densities of larval fish were prevalent in the ichthyoplankton tows during the 1991 period; therefore intra- and interspecific competition for limited food resources may have been the cause of slower growth (density-dependent growth) in yellowfin tuna larvae The highest mean seasurface temperature and the lowest mean wind stress occurred during an El Niño-Southern Oscillation (ENSO) event during the 1997 period. There appeared to be no clear association between these environmental factors and larval growth rates, but the higher temperatures may have caused an increase in the short-term growth of otoliths in relat

A History of the Pearl Oyster Fishery in the Archipielago de las Perlas, Panama

The pearl oyster, Pinctada margaritifera mazatlanica, was once found around the Archipielago de las Perlas in Panama in abundance and it supported a substantial fishery by hard hat divers. The products were pearls, shells used for making buttons, and meats used locally for food. After the mid 1920’s, the fishery declined due to overfishing, and by the 1940’s it was nearly gone. The oysters began to repopulate the grounds during the 1970’s, but the oysters remain relatively scarce. Fishing has since resumed on a small scale by skin divers using face masks.

Regional study on social dimensions of MPA practice in Central America: cases studies from Costa Rica, Nicaragua, Honduras and Panama

This research focuses on the social dimensions of marine conservation, and makes an assessment of the experiences of coastal and fi shing communities with regard to the governance of MPAs in Central America, based on case studies from Honduras, Nicaragua, Costa Rica and Panama. It examines the national contexts of the above countries in relation to the governance of MPAs. Furthermore, it analyzes the social impacts of MPAs on coastal communities by gathering the experiences and the voices of the communities and institutions involved, and reflects on how to build bridges in the search for forms and models of conservation that respect human rights and which are able to successfully integrate into local development efforts without affecting cultural and/or social patterns. To this end, this monograph looks at nine case studies across the region: in Honduras, the Islas de la Bahia-Guanaja Marine National Park, the Cayos Cochinos Marine Archipelago Natural Monument, and the Cuero and Salado Wildlife Refuge; in Nicaragua, the Chacocente Wildlife Refuge; in Costa Rica, the Guanacaste Conservation Area, the Ballena Marine National Park and the Golfo Dulce Responsible Fishing Area; and, in Panama, the Nargana Protected Area, in the Comarca de la Biosfera Guna-Yala, the Bastimentos Island Marine National Park, and Bocas del Toro.

Estudio regional sobre las dimensiones sociales en el manejo de areas marinas protegidas: casos en Costa Rica, Nicaragua, Honduras y Panama

Explora la percepción de las personas residentes en las comunidades costeras vinculadas a los espacios marinos protegidos en Honduras, Nicaragua, Costa Rica y Panamá. Profundiza, a partir de estudios de caso y el análisis comparativo, los temas de gobernanza, derechos humanos y distribución justa y equitativa de beneficios derivados de la conservación. Los resultados destacan que los esfuerzos de conservación marina no han logrado establecer puentes que permitan satisfacer las necesidades sociales. Las comunidades han sido excluidas de los procesos de toma de decisiones, y los costos de la conservación han recaído en las pueblos costeros. Se plantean recomendaciones orientadas hacia el desarrollo de procesos de conservación marina y desarrollo local en aras de tender puentes en la búsqueda de formas y modelos de conservación marina que sean respetuosos de los derechos humanos y promuevan “el buen vivir” de las comunidades en territorios marino-costeros.
