An Introduction on Microplastics
The destruction of aquatic ecosystems including micro-plastics is a major issue facing aquatic conservationists globally. This issue includes microplastic pollution, acidification, and over-fishing. Microplastics are defined on Wikipedia as very small pieces of plastic that pollute the environment. We here at aquatic live food have produced a new survey net designed to help with this issue. The net will assist researchers to gather data on microplastics and to sample surface plankton more efficiently.
Our aim was to do some sea trials using our prototype net. We wanted to establish optimal collection sizes to ensure our net would fair well in all sea & weather conditions. As a result, the micro-plastics net worked effectively and it was robust enough to withstand exposure to aquatic environments!
The ALF Manta Micro-Plastics Net is easily as well when operated in calmer inshore waters and on rivers and lakes and waterways.
Whales and Plastic
The oceans are full of planktonic prey and predatory fish, both of which attract different species of whales. Despite the availability of good sources of food, research points to a bleak future for cetaceans and around the world.
Filter-feeding baleen whales like humpbacks and fin whales, toothed sperm whales and killer whales all are consuming enormous amounts of plastic. The debris blocks their digestive tracts and, scientists suspect, delivers toxic chemicals into their bodies. But no one quite understands why whales are eating plastic in the first place—or precisely what these intoxicants do to their bodies.
A filter-feeding adult humpback draws in nearly 19,000 litres of water and one and a half tonnes of krill each day. Imagine how much plastic they trap!
Ocean currents appear to carry both nutrients and microplastics into whale feeding grounds as well as other Marine Mammals. Whales are eating microplastics, so the key question becomes: what are microplastics actually doing to these animals?
The whales consuming microplastics my not be a digestion issue however the problem of having microplastic in the body could be a chemical problem, the toxins microplastics tend to harbor my cause ulcers, or other reactions as well as possible chemical poisoning.
By providing appropriate tools for researchers and other interested parties there is a good chance the problematic possibilities can be averted.
Microplastics—tiny particles of plastic less than five millimetres in size—are polluting rivers and ponds along with chemical contaminants. The particles come from cosmetics such as ex-foliating body scrubs or are washed out of synthetic fabrics. Until now, scientists have primarily investigated the concentrations and effects of microplastics in seawater.
The Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in Berlin in testing how high concentrations of standardised plastic particles affect water fleas. Their experiments showed that the ubiquitous residents of bodies of freshwater ingest tiny particles of a micrometer, or one-thousandth of a millimetre in size. This clearly limited the water fleas’ mobility, and as a result, their intake of nutrients.
