The study's findings challenge previous assumptions about the role of jellyfish in marine food webs and highlight the need for further research on gelatinous zooplankton's impact.

Climate change may lead to shifts in vital Pacific Arctic fisheries

Climate change is expected to shift the distribution of eight commercially important marine fish and invertebrate species northwards due to warmer water temperatures and loss of sea ice habitat. This could lead to changes in the abundance and economic viability of fisheries, with some species potentially benefiting while others decline.

The most endangered fish are the least studied

A recent study published in Science Advances found that the most threatened reef fishes receive less attention from scientists and the public due to commercial value vs. ecological importance. Small fish families like blennies and gobies are underrepresented despite their crucial role in trophodynamics.

Hatcheries can boost wild salmon numbers but reduce diversity

A study by University of Alaska Fairbanks researchers found that hatchery-raised fish are interbreeding with wild populations, reducing diversity and increasing resilience. This can have long-term consequences for wild population recruitment and adaptation to future changes.

Artificial light is a deadly siren song for young fish

New research reveals that artificial light at night (ALAN) attracts larval fish to artificially lit environments, reducing their chances of survival. ALAN has been shown to lower fish growth rates, metabolic rates, and overall survival, with serious consequences for fish conservation.

Previously uncharacterized parasite uncovered in fish worldwide

A new group of parasites, ichthyocolids, have been discovered in many marine fish species around the world, according to a recent study published in Current Biology. The parasite is widespread and has been found in all oceans, with potential implications for commercial fishing and oceanic food webs.
