Trawling for Fish May Unleash as Much Carbon as Air Travel, Study Says
The report also found that strategically conserving some marine areas would not only safeguard imperiled species but sequester vast amounts planet-warming carbon dioxide, too.

For the first time, scientists have calculated how much planet-warming carbon dioxide is released into the ocean by bottom trawling, the practice of dragging enormous nets along the ocean floor to catch shrimp, whiting, cod and other fish. The answer: As much as global aviation releases into the air.

A team of 22 scientists have used data from the Integrated Marine Observing System (IMOS) to track the movements of marine organisms during the Covid-19 lockdown in a new study, revealing the impact of human activities on marine species in Australian waters.
With shark cage-diving as a case study, the research team, led by Associate Professor Charlie Huveneers from Flinders University, monitored the movements and residency of two marine species, white sharks and yellowtail kingfish, over a 51-day period during the longest break in cage-diving activity at the Neptune Islands near Port Lincoln for over 20 years.

Unknown, unloved and in strife – Aussie battler sharks and rays fished to brink of extinction
Shark and ray species unique to Australian waters are in danger of extinction from commercial fishing unless fishing practices and rules are improved, a new independent report commissioned by the Australian Marine Conservation Society (AMCS) and Humane Society International (HSI) has found.
Half of Australia’s 322 species of shark and ray are found nowhere else in the world (which is known as ‘endemic’), and yet these true-blue Aussie battlers are in serious trouble. Species such as the Critically Endangered whitefin swellshark and the Vulnerable eastern angelshark are still declining[1].

Big Step Forward for $50 Billion Plan to Save Louisiana Coast
An environmental assessment said the project’s next step would largely benefit coastal areas, though it might also affect some marine life, especially dolphins.
