Spatio-Temporal Declines in Philippine Fisheries and its Implications to Coastal Municipal Fishers' Catch and Income
The problem of overexploitation in global fisheries is well-recognized. However, published assessment of fisheries spatio-temporal trends at the national scale is lacking for many high biodiversity developing countries, which is problematic since fisheries management is often implemented at the local or national levels. Here, we present the long-term spatio-temporal trends of Philippine fisheri...

Yet, small-scale fishers are seldom explicitly considered in regional fisheries management and their contribution to national fish supply tends to be greatly under-estimated compared to industrial fisheries. Lack of...
متن کاملKeeping Food on the Table: Human Responses and Changing Coastal Fisheries in Solomon Islands

In the Pacific Islands coastal fisheries provide basic subsistence needs for millions of people. A decline in fish catch would therefore have profound impacts on the ...
متن کاملGood news, bad news: global fisheries discards are declining, but so are total catches

When the species in question are of low value, or protected, this ‘by-catch’ is often thrown overboard as ‘discards’, the retained part of the catch constituting the landings. The amounts of fish discarded are generally highly areaand gear-specific, but can be high; for example, discards in tropical shrimp trawl fisheries ...
