According to Study: Lake trout adjust their behavior in the face of a changing climate

Fish

Lake Trout according to a recent study have been discovered to have a remarkable ability to adjust their behavior in the face of changing water temperatures a U of M graduate student and his colleagues found.    According to this newly discovered research, Canadian scientists have discovered that certain lake predators are altering their behavior due to climate change, revealing what the future may hold for these fish and their food. For years scientists told tales of fish such as Lake Trout adapting their feeding behavior as temperatures change, but…

Warmer waters from climate change will leave fish shrinking, gasping for air

Warmer waters

Fish are expected to shrink dramatically in warmer waters. Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change. A new study by researchers at the University of British Columbia provides a deeper explanation of why fish are expected to decline in size. “Fish, as cold-blooded animals, cannot regulate their own body temperatures. When their waters get warmer, their metabolism accelerates and they need more oxygen to sustain their body functions,” said William Cheung, co-author of the…

Species of Female Fish and their Method of Reproduction

Male fish and Female fish

An all female fish (freshwater) species called the Amazon molly that inhabits rivers and creeks along the Texas-Mexico border is living proof that sexual reproduction may be vastly over-rated according to WASHINGTON (Reuters). Meanwhile, Female fish can breed a new species if they aren’t choosy about who is Mr. Right. Fish will mate with a species outside their own if the male’s coloring is attractive enough or if the female can’t see him properly, according to new research. Such ‘mistakes’ in mate choice can lead to the evolution of new…
