Stirred up sediment impacts sea sponges
- "Sediment stirred up from fishing activity has a detrimental effect on reef-building sea sponges in northern British Columbia, according to a new study by University of Alberta biologists. The sediment is kicked up during human activities such as bottom trawling, where a weighted net is dragged across the seafloor. It includes organic matter as well as clay and silt, which can smother sponges from the outside or, if taken into their filtration system, clog them." - Excerpt from University of Alberta
