Wakatobi National Park has a tropical marine ecosystem with typically dynamic aquatic resources, and it also has a potentially massive number of groupers such as red (Plectropomus leopardus) and black groupers (Plectropomus areolatus). However, the sustainability of the grouper resources has not been managed effectively and environmentally friendly. This study aims to determin...

Bioeconomic analyses of spatial fishery models have established that marine reserves can be economically optimal (i.e., maximize sustainable profit) when there is some type of spatial 2 heterogeneity in the system. Analyses of spatially continuous models and models with more than two discrete patches have also demonstrated that marine reserves can be economically 4 optimal even when the system ...

We, members of the Association Française d’Halieumétrie, share the conviction that European fisheries have a future. It is time to get off the wrong track. Radical change is required to embark on the path of sustainable development and truly implement the ecosystem approach to fisheries. Today, high fishing pressure is deployed to catch a rare resource, which in return is responsible for the ra...

Although contemporary trends indicative of evolutionary change have been detected in the life-history traits of exploited populations, it is not known to what extent fishing influences the evolution of alternative life-history tactics in migratory species such as salmonids. Here, we build a model to predict the evolution of anadromy and residency in an exploited population of brook charr, Salve...

Using estimates of the primary production required (PPR) to support fisheries catches (a measure of the footprint of fishing), we analyzed the geographical expansion of the global marine fisheries from 1950 to 2005. We used multiple threshold levels of PPR as percentage of local primary production to define 'fisheries exploitation' and applied them to the global dataset of spatially-explicit ma...

BACKGROUND In Kasensero fishing community, home of the first recorded case of HIV in Uganda, HIV transmission remains high with an incidence of 4.3 and 3.1 per 100 person-years in women and men, respectively, and an HIV prevalence of 44 %, reaching up to 74 % among female sex workers. We explored the social contextual factors for the high HIV transmission at Kasensero to inform future policy an...

Indigenous knowledge (IK) can be broadly defined as the knowledge that an indigenous community accumulates over generations of living in a particular environment whose scientific validity is not proven. ITKs could very well provide a panacea in building the technology gap required for the sustenance of the fisheries sector. There are numerous ITKs which is available in fisheries sector whose kn...

Activities of fishermen in the Bay of La Paz, B. C. S. are focused to satisfy the local demand of fish and shellfish by using approximately 300 small outboard crafts equipped with gillnets. Sea lions in this Bay attack the fishes captured damaging both product and gear. We did experimental gillnet throws to determine the frequency and preferences of sea lions in fishing areas. 52 experimental g...

Fisheries catches represent a net export of mass and energy that can no longer be used by trophic levels higher than those fished. Thus, exploitation implies a depletion of secondary production of higher trophic levels (here the production of mass and energy by herbivores and carnivores in the ecosystem) due to the removal of prey. The depletion of secondary production due to the export of biom...
