Marine microplastics are emerging pollutants that impact across levels of marine food chain at a global scale. Its presence was determined on Sardinella lemuru, a commercial pelagic fish that are harvested generally in the Northern Mindanao, consumed locally, and exported worldwide as bottled or canned sardine products.  The stomach contents of 600 sardines were examined visually under...

Fishing and ancillary industries are commonly perceived to be of significant social and economic value by virtue of their geographic location. Past socio-economic studies of fisheries and related industries largely confined themselves to analysing demographic statistics and relating these to official port fish landings data and descriptions of processing and ancillary industries. Despite these ...

Populations of small pelagic fish are strongly influenced by climate. The inability of managers to anticipate environment-driven fluctuations in stock productivity or distribution can lead to overfishing and stock collapses, inflexible management regulations inducing shifts in the functional response to human predators, lost opportunities to harvest populations, bankruptcies in the fishing indu...

In developing countries, official statistics, national accounts, and economic development initiatives generally focus on commercial, often exportoriented fisheries, which are often perceived to be the major economic contribution of fisheries. While small-scale, non-commercial fisheries, especially near-shore subsistence fisheries, have been recognized as fundamental for social, cultural, and fo...

1. Fisheries bycatch has been implicated in declines of many long-lived marine vertebrate populations, but bycatch impacts on these populations vary according to spatio-temporal overlap in fisheries operations and critical ontogenetic habitat, as well as to characteristics of fishing gear. 2. To provide a framework for comparing the relative impacts of different fisheries on populations of logg...

Globally the majority of commercial fisheries have experienced dramatic declines in stock and catch. Likewise, projections for many subsistence fisheries in the tropics indicate a dramatic decline is looming in the coming decades. 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 ...
