Most years, Southern California on the US west coast is the site of a special marine life aggregation, treating locals to one of the most unique dives in the world. Hundreds of thousands of market squid (Doryteuthis opalescens) swim into recreational dive depths to mate and lay an expansive canvas of egg baskets (collections of eggs) across the sandy substrate.
The lead researcher, Kye Adams, a PhD student at the University of Wollongong, said that shark fishermen should be made aware of the danger of inducing abortions in pregnant sharks, rays, or skates. So far, the loss of the young aborted by fished sharks has been ignored by both science and fishermen.
Adams said, "It's quite prevalent across a lot of species and also seems to be not well known by both researchers and recreational fishers. "They don't realise these events are abortions, they think they are witnessing a natural birth."
The (34,000 Swedish Krona) package consists of a SE7EN E-module, two HP-sensors and a HUD.
The deadline for this upgrade is 24th December 2017 and it cannot be combined with any other offers. The old MKVI e-module must be returned to Poseidon and the owner will also need to either buy a M28 or a Paddle with a can connector.
Poseidon has also confirmed that there will be a minor upgrade for current SE7EN owners so that their rebreathers are solid state sensor ready.
Admittedly, the idea of protecting seagrass is not as “glamorous” as protecting the rainforest, but this marine vegetation is essential to both marine life and humans. A new study by scientists from Cardiff University, Swansea University and Stockholm University, and published in the Fish and Fisheries journal, highlights the global importance of seagrass to fisheries.
“Wherever you find seagrass and people, there is most certainly fishing,” said Dr Leanne Cullen-Unsworth, from Cardiff University’s Sustainable Places Research Institute.
