Bluefin Tuna: Mediterranean fishing closed early

Here's a post today from Mike at Beqa Adventure Divers regarding the Bluefin Tuna fisheries in the Mediterranean:

Med Tuna Fisheries closed!

Betcha you remember
this!

Well, as I said, not all hope is lost!
The much-reviled European Fisheries Commission has closed the Mediterranean Tuna fisheries one week early - much like they did last year! The situation of the Northern Bluefin continues to be dire and the Gulf oil spill has likely made things even worse (read this!) - still, this is good news as it clearly illustrates the desire to enforce sustainable fisheries. As is this - and I may add, very much contrary to these shenanigans!

The equally
reviled ICCAT will meet in Paris this November, this after a host of preparatory meetings. This is the body that has the mandate, and contrary to CITES, the know how to regulate the Atlantic Tuna fisheries. Members here. The fisheries in the Mediterranean are regulated by the GFCM - members here.

Has anybody started talking to them - inclusive of talking to Japan?
And even more importantly: is anybody stepping forward with ideas and funds aimed at mitigating the impact of possible quota reductions, especially when it comes to the poorer African and Caribbean countries - oh, and Greece? All whilst wielding the stick, as in leveraging development aid?

All kidding aside: has anybody learned the lessons of Doha and developed a realistic, and above all, unified strategy - or will the NGOs continue to be naive, badly prepared and fragmented, only to incur yet another inevitable defeat?


We shall see!


I have written several posts in the past regarding the decimated bluefin tuna population, the commercial fishery agencies that have dropped the ball time and time again, and the international organizations that have caved in to pressure from countries where the market demand is high. But more meetings are coming. The big question is will anything change? Will something be done before we say "Sorry, Charlie" for the very last time and watch an important pelagic species fade into extinction?

Oceanic White Tip Sharks: curious pelagic predators with an unfair reputation

A sleek but muscular body gliding effortlessly through cobalt blue water, its rounded snow-capped dorsal fin slicing the water just below the surface, the Oceanic White Tip Shark is one of the premier pelagic (open ocean) predators.

Beqa Adventure Divers's blog picked up on a series of terrific photos of oceanic white tips, posted by LupoDiver on a recent South Atlantic trip with Jim Abernethy's Scuba Adventures.

Oceanic white tip sharks are important open ocean predators and scavengers. As with most other sharks, they play a critical role in keeping the oceanic backyard clean and the populations of their prey healthy by culling the weak, injured, and sick. They are intensely curious as they do not live in a world of wall-to-wall animals, so anything that catches their attention either visually or by scent is quickly investigated.

Unfortunately, these sharks also have a bad reputation carried down through history as a man-eater. Often attracted by the low frequency sounds given off by sinking ships (not your typical underwater background noise), particularly from sinking warships, these sharks were known to attack sailors in the water - their hunting/scavenging instincts piqued by blood from wounded sailors. Sadly, what began as natural curiosity and a reaction to food stimulus in a limited-prey environment turned into a fearsome oceanic killer reputation. Turn down the anxiety level a few notches and you get a lot closer to the truth, as LupoDiver and his fellow divers discovered on their trip.

Beqa Adventure Diver also comments on LupoDiver's picture of a blue shark, another pelagic predator whose numbers have dropped considerably over the years, a favorite target for the commercial shark fisheries.

My first unexpected encounter with a shark in open water was with a beautiful blue shark, over 20 years ago, off Santa Cruz Island which is part of California's Channel Island chain. Following that, my first cage diving experience was being surrounded by a group of blue sharks. Now, Southern California's blue shark diving operations have all but disappeared and, sadly, I suspect I may never come across another blue shark without a lot of chumming and patience.

LupoDiver, treasure your experience with the oceanic white tip and blue shark. Like the great white shark and others, these are very unique and important members of a healthy marine ecosystem. Without them, both the oceans and mankind are the lesser for it.
