Wetlands in most parts of the world are under threat of over-exploitation partly because their socio-economic value is not well known. Yala Wetland, the largest freshwater wetland in Kenya, with a large part of it bordering Lake Victoria’s shoreline, faces even greater threats of extinction. This wetland measures about 17,500 ha and is host to a number of indigenous fish species, animals and plants which are exploited by the local communities for subsistence and commercial purposes.There has been pressure to reclaim portions of this wetland for agricultural activity. So far, 2,300 ha has, indeed, been drained for commercial agriculture. Furthermore, it is difficult to control effort in the exploitation of the remaining wetland resources since the... |

Exploitation, uses and current status of the West Indian topshell Cittarium pica (Mollusca: Gastropoda, Trochidae) along the Colombian Caribbean coast. The West Indian topshell, Cittarium pica is a common and conspicuous gastropod that thrives in Caribbean intertidal rocky shores and has been used for food by men since pre-Columbian times. Although, the exploitation of this resource is practiced only by artisanal fishermen and mainly for self-consumption, its abundance has noticeably reduced in the last ten years, so the species has been included in the endangered animal lists of several Caribbean countries, including Colombia. The present study was carried out to assess the current status of the population of C. pica along the Colombian Caribbean mainland... |

Un análisis de los principales indicadores pesqueros (CPUE, esfuerzo y talla media de captura) fue realizado en base a información obtenida del seguimiento de la pesquería de la concha prieta durante el año 2009 en los sitios de desembarque más importantes. Los puertos de San Lorenzo y Hualtaco registraron los desembarques más altos (8.8 y 4.8 millones de conchas, respectivamente). Los rendimientos en CPUE oscilaron entre 95 y 122 conchas/conchero/día pesca,mientras que el esfuerzo promedio se encontró entre 38 y 331 concheros/día pesca. El porcentaje de conchas no comerciales fue superior al 45% (A. tuberculosa) y a 35% (A. similis) en cada puerto de desembarque. La condición reproductiva fue muy variable a lo largo del año en relación a los estadios de... |
