One study found that when a cigarette was soaked in water, it released enough toxins to be poisonous to both marine and freshwater fish in the water. They found that the cigarettes were most toxic when they still had some tobacco in them.[128]...
Overall, freshwater input and ocean connectivity of coastal Arctic lagoons appear to be important drivers of fish trophic ecology, and should be carefully monitored in the face of anticipated changes in the region, to conserve important subsistence harvest species....
The colonial settlements of Tasmania are built upon events and massacre sites similar to this place. This extends to both the academic and industrial institutions of the island, and indeed the accumulated knowledge and understanding of the island. Even though piyura kitana has since been returned t...
Some fish live in freshwater. Rivers,ponds and most lakes are freshwater.All fish are cold-blooded animals. This means that their body temperature changes with the temperature around them. They are as warm or as cool as the water they live in. But fish will get weak if the water becomes...

The ocean is our life support system as the ocean regulates our climate, absorbs the dangerous carbon dioxide and generates the oxygen we need to breathe. TheWorld Ocean accounts for 97% of all waterthat exists on our planet - the other 3 % is freshwater locked up in the ice caps, rivers...
“And then all sorts of fertilizer (肥料) and food have been dumped in the water there," says Ducklow. Habitat destruction also leaves coastal areas prone to flooding.“ A lot of our freshwater comes from the ocean as rain, " adds Shannon, an ocean scientist. Rain helps crops grow and...
Also, the findings helped explain that, over evolutionary time, many fish groups moved from ocean water to freshwater and some became freshwater fish while others evolved into the earliest tetrapods, land-dwelling vertebrates. The researchers from and Universities of Birmingham, Manchester, Pennsylvania...
Sometimes companies destroy mangrove(红树林) forests and other sensitive habitats in order to build fish farms. Habitat destruction also leaves coastal areas easily flooding. “A lot of our freshwater comes from the ocean as rain,” adds Shannon. Rain helps crops grow and provides drinking water....
“We know that small fish have a big impact in our ocean food webs,” said Jessie Ritter, director of Water Resources and Coastal Policy for the National Wildlife Federation. “That’s why a strategy to ensure smart, science-based management of forage fish species is so important to overall...
