WALVIS BAY – A Norwegian scientist on Saturday reaffirmed the depletion of the pilchard fish species in Namibian waters after conducting a survey along the country's coastline.

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.

In the coming decades, warming ocean temperatures could stunt the growth of fish by as much as 30 percent, according to a new study in the journal Global Change Biology.

Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change, a study has warned.

Fish may be actively seeking out plastic debris in the oceans as the tiny pieces appear to smell similar to their natural prey, new research suggests.
