Also known as the “slimehead,” the orange roughy has a wide-ranging habitat that includes the coasts of New Zealand, Australia, Namibia and the northeast Atlantic Ocean. Its life expectancy is up to 149 years, and it reaches sexual maturation age between 20 and 32 years, making it the epitome of a species inherently vulnerable to overfishing. The pressure of overfishing is amplified by fishermen’s tendency to trawl for orange roughy when the fish congregate to feed and breed. The resulting catches wipe out generations. Though the IUCN hasn’t reviewed this species to determine if it is endangered, a number of other organizations have recognized the significant decline in its numbers after only 25 years of commercial harvesting.
Bycatch are sea creatures caught unintentionally. This can either be ocean dwellers other than the desired species or juveniles of the desired species.
This species of North Atlantic fish grows to about 20 inches in length and can live as long as 50 years. Like other overfished species, the Acadian redfish is slow-growing and reaches reproductive age late — at about eight or nine years old. Intensive trawling over the last 10 years has led to the smallest yields since commercial fishing of the species commenced in the 1930s. Worse, the Acadian redfish has been subject to pirate fishing, or fishing done in violation of environmental law. For these reasons, the IUCN lists the species as endangered.
Trawling is a fishing technique where a large, deep net is pulled behind a boat. Often this net drags on the ocean floor, stirring up sediment and altering seafloor habitat. The effects of trawling can actually be seen on satellite images taken from space.
While the beluga sturgeon is popular for its fillets, its eggs, known as “true caviar,” are regarded as a delicacy. Native to the Caspian Sea, these ancient fish can grow to 15 feet in length, weigh more than a ton and live to be 100 years old. Due to the popularity of their eggs, they’re heavily overfished — typically with gill nets. This particularly problematic because this species that doesn’t reach sexual maturity until 20 or 25 years of age. In addition to fishing pressures, beluga sturgeon suffer from habitat reduction, having lost 90 percent of their historic spawning grounds over the past several decades. Because of these pressures, the IUCN classified the beluga sturgeon as endangered, and the population is expected to continue its decline.
Gill nets are nets that sit like a fence on the ocean floor. When a fish that is tcoo big to swim through the net tries to swim back out, it gets caught by the gills.
Found in the North Atlantic Ocean, the Atlantic halibut is the largest of the flat fish species.
Boasting a 50-year lifespan, it can reach a length of 9 feet and weigh up to 1,000 pounds. But because this slow-growing fish doesn’t become sexually mature until it’s 10 to 14 years old, it’s particularly susceptible to overfishing. While Atlantic halibut are normally caught with hooks-and-lines, they’re often caught as bycatch in bottom trawl fisheries. The IUCN classifies them as endangered, and their numbers are not expected recover in the near future. This has prompted the United States to ban Atlantic halibut fishing in its coastal waters.
The Atlantic bluefin
The Atlantic bluefin tuna is one of the largest, fastest, and most gorgeously colored of all the world’s fishes. Their torpedo-shaped, streamlined bodies are built for speed and endurance. Their coloring—metallic blue on top and shimmering silver-white on the bottom—helps camouflage them from above and below. And their voracious appetite and varied diet pushes their average size to a whopping 2 meters in length and 250 kilogram, although much larger specimens are not uncommon.
Unfortunately for the species however, bluefin meat also happens to be regarded as surpassingly delicious, particularly among sashimi eaters, and overfishing throughout their range has driven their numbers to critically low levels.
Atlantic bluefins are warm-blooded, a rare trait among fish, and are comfortable in the cold waters off Newfoundland and Iceland, as well as the tropical waters of the Gulf of Mexico and the Mediterranean Sea, where they go each year to spawn. They are among the most ambitiously migratory of all fish, and some tagged specimens have been tracked swimming from North American to European waters several times a year.
They are prized among sport fishers for their fight and speed, shooting through the water with their powerful, crescent-shaped tails up to 70 kilometers per hour. They can retract their dorsal and pectoral fins into slots to reduce drag. And some scientists think the series of “finlets” on their tails may even serve to reduce water turbulence.
Bluefins attain their enormous size by gorging themselves almost constantly on smaller fish, crustaceans, squid, and eels. They will also filter-feed on zooplankton and other small organisms and have even been observed eating kelp. The largest tuna ever recorded was an Atlantic bluefin caught off Nova Scotia that weighed 679 kilograms.
Bluefin tuna have been eaten by humans for centuries. However, in the 1970s, demand and prices for large bluefins soared worldwide, particularly in Japan, and commercial fishing operations found new ways to find and catch these sleek giants. As a result, bluefin stocks, especially of large, breeding-age fish, have plummeted, and international conservation efforts have led to curbs on commercial takes. Nevertheless, at least one group says illegal fishing in Europe has pushed the Atlantic bluefin populations there to the brink of extinction.
Due to odd circumstances, I had the privilege to attend not one, but two IDC’s with Camille. Needless to say they were both amazing learning experiences. Camille’s attention to detail and strict but flexible teaching style meant only the best experience and made the IE a breeze.
His ability to teach in numerous languages makes understanding for multi-lingual classes easy and his experience means he can relate any information to you personally so that you have no trouble with the tricky bits.
Needless to say, if i were asked where to do an IDC i would send the person asking straight to Camille.
Thanks for a great time and making a scruffy kid like me a competent instructor, Camille!

Today, there are three living species of this Shark:
But experts are still puzzled about the possible existence of a fourth species. This mystery continues to elude enthusiasts, but many believe it’s only a matter of time before this fourth species is confirmed.
It’s origin is also surrounded by mystery. Most likely, the closer relative of the Fox Shark is the Megamouth Shark. Scientific studies are ongoing to try and resolve the many mysteries that surround this unusual and unique fish.
The largest known Thresher Sharks reach a length of more than 6 meters (20ft) and weigh 600 kilograms (216 pounds). Bigeye Threshers are normally the largest with Pelagic Threshers being the smallest.
These are slow growing sharks. They reach their maturity between 8 and 13 years old and live about 22 years. Again, there is quite a bit of mystery here. Some believe this shark is capable of living much longer, but simply hasn’t been verified.
Although Thresher Sharks love open and deep waters, they are also found in shallow waters near coastal areas. They are generally not found deeper than 500 meters.
They favor the Pacific and Indian Oceans, especially at the continental shelves of America and Asia. But the exact habitat, again, remains largely a mystery. There are seen Threshers around Bali and the Gili Islands, Indonesia.
In addition to electro receptors that all sharks have, which gives them they ability to detect electrical impulses from living creatures, they also have an extraordinary heat exchanger system. They’re called “endoderms”, which means that they have special thermoregulation. In other words, they produce heat through an internal body mechanism such as enhancing their metabolism and muscle shivering. This is largely a unique feature in Thresher Sharks.
For the most part, they are rogue mavericks and remain largely independent. But on occasion, they join together in large groups. This phenomenon has mostly been observed in the Indian Ocean. The reasoning for these get togeathers is currently unknown.
These are very athletic sharks. They are known for slaying their prey with their huge tails and are famous for special jumping techniques and behavior called “breaching” where they jump out of the water and into the air.
While hunting, they launch themselves with their whole body out of the water and perform wild turns. They love to hunt schools of fish in the open Ocean waters and prefer Tuna, Mackerels, and sometimes go after certain breads of Seabirds.
As with so many other aspects of this mysterious shark, the reproductive behavior is not well explored. We do know that they are Viviparous, which means that eggs evolve in the uterus until birth.
In general, they give birth to 2 to 5 pups at a time and the pups normally have a length of 120 to 160cm.
There is a special phenomenon called “oophagy” in the womb. The pups actually leave their eggs, still in the womb, and feed themselves with all the unfertilized eggs.
Relationship with Humans
The largest threat to the Thresher Shark is human fishing. Many fisherman catch them for sport, while others catch them for their fins, liver oil, tails, and flesh.
Due to recent population depletion, new laws are being enacted to help protect this species from upsetting the fragile balance of the marine ecosystem, especially since these sharks have a low reproductive rate as compared to other sharks.
This species poses very little threat to humans. The largest threat of injury is divers getting hit with the enormous tail. Attacks of any kind on humans are almost unheard of.
These streamlined blue and yellow fish are found around coral reefs where they feed on zooplankton.
They are approximately 40cm in length.
This silvery-blue fish has a fusiform, streamlined body, long dorsal fin and a forked tail. Some species have yellow or pink markings. All have small eyes and a tiny, distensible mouth. Closely related to snappers.
They are found in Indian and West Pacific oceans. Around the Gili Islands you will find them at Sharkpoint, Halik, Soraya, Deep Turbo etc.
They inhabit coastal areas, mainly near coral reefs.
Unlike their predatory relatives, the snappers, fusiliers are plantivores. They form large, mid-water feeding schools.
These schooling fish are often found around cleaning stations or along reef slopes. At night they shelter within the reef.
