A new study has revealed that enriched rearing of juvenile fish significantly enhances the survival of fish from bacterial infection commonly seen in rearing conditions. That may also improve the post release survival of the fish after stocking into the wild.

A new species of giant penguin -- about 1.6 metres tall -- has been identified from fossils found in Waipara, North Canterbury in New Zealand.

Research revealed a unique feeding strategy of a marine sponge, wherein the sponge animal acquires important components of its diet from symbiotic bacteria living within the sponge.

Microbial communities living in deep aquatic sediments have adapted to survive on degraded organic matter, according to a new study.

Scientists have discovered how diatoms -- a type of alga that produce 20 percent of the Earth's oxygen -- harness solar energy for photosynthesis. The discovery could help lead to more efficient and affordable algae-based biofuels and combat climate change from fossil fuel burning.

In parts of the South, there are stories about an invasive floating weed, which forms such a dense mass that it enables small animals to walk across water.

New research published today in the journal Parasitology shows how the prehistoric inhabitants of a settlement in the freshwater marshes of eastern England were infected by intestinal worms caught from foraging for food in the lakes and waterways around their homes.

A team of international scientists has found an environmentally friendly way of producing potential sunscreens by using cashew nut shells, a waste material.

Rivers in Europe are so congested with concrete obstructions like weirs, bridges and other man-made barriers that they no longer flow freely, which harms the wider environment. Removing these blockages could restore these vital aquatic ecosystems to their former glory.

Asian carp are capable of surviving and growing in much larger portions of Lake Michigan than scientists previously believed and present a high risk of becoming established, according to a new modeling study from University of Michigan researchers and their colleagues.
