The world's fisheries will be, on average, 20 per cent less productive in the year 2300, according to a study.

KOCHI: There is growing, substantial evidence that climate change has affected fish and other marine population over the decades.

KOLKATA: From Tollygunge to Kidderpore and Gariahat to Amherst Street, every time you buy vegetables, fish, chicken or grocery from roadside markets, you are taking home dollops of heavy metal pois

Anthropogenic climate warming could lead to water temperatures in some parts of the world exceeding the thermal survival limits of the fish species living there now, according to new research from

The mucky sediment below fish farms usually teems with antibiotic-resistant bacteria.

Tool use has allowed humans to become one of the most successful species. However, tool-assisted foraging has also pushed many of our prey species to extinction or endangerment, a technology-driven process thought to be uniquely human. Here, we demonstrate that tool-assisted foraging on shellfish by long-tailed macaques (Macaca fascicularis) in Khao Sam Roi Yot National Park, Thailand, reduces prey size and prey abundance, with more pronounced effects where the macaque population size is larger.

Between now and 2050 the planet’s population is expected to rise by a third, from 7.6bn to 9.8bn. Those extra mouths will need feeding, and not just with staples.
