Dubai’s largest reef, consisting of over 1,100 coral-encrusted rocks, has been moved to a new location to protect it from future development. Details of the relocation have been kept secret for more than a year to ensure its success, and the transfer was therefore not announced until today, on World Environment Day.

As reported earlier, an ill-fated eel somehow ended up in the butt of an allegedly constipated Chinese gentleman. Two European fish experts have now taken a closer look at a photograph of the eel in question and given their expert opinion on its identity.

Several types of commonly used fish egg disinfectants increase the risk of swim bladder disorder in fish, a new study from Israel reveals.

In several species of fish, such as the cichlid species Neolamprologus pulcher, it is common for subordinate females to help an unrelated dominant breeding pair raise their young. The reason behind this seemingly altruistic behaviour, known as alloparental care, has puzzled scientists for many years and one of the most widely spread hypotheses put forward has been the ‘pay-to-stay’ hypothesis. According to the ‘pay-to-stay’ rationale,

Just like dolphins, sharks can be trained to roll over to be cuddled by humans. In experiments carried out in the United States, several species of shark allowed themselves to be picked up from the water and cuddled by their trainers.

Scientists from the U.S. Geological Survey (USGS) have revealed that largemouth bass injected with oestrogen produces less hepcidin than normally. Hepcidin is an important iron-regulating hormone in fish, amphibians and mammals, and researchers also suspect that hepcidin may act as an antimicrobial peptide.

Two years after destroying part of the Belize barrier reef, an U.S. skipper has been ordered by a Belize court to pay BZ$3.4 million, roughly equivalent of US$1.7 million, for the damage.

Hundreds of thousands of tourists visits Green Island each year to enjoy scuba diving and snorkelling among its beautiful reefs, but no sewage treatment exists so an average of 1,500 tons of untreated sewage is flushed into the sea on a daily basis.

As reported earlier, fish populations may adapt and change in response to significant fishing pressure. Researchers are now suggesting that the genetic make-up of cod in the Atlantic Ocean might be changing, since cods genetically predisposition to seek out shallower waters are more likely to end up in nets or on fishing lines, while deep-dwellers are more likely to survive and reproduce.

This Saturday, about 55 False killer whales (Pseudorca crassidens) stranded on Long Beach, Kommetjie, in South Africa. Both adults and calves began to appear on the shore around 5.30 in the morning, perhaps as a result of the bad weather. This incident is the second large stranding in a short period of time; in March about 80 whales stranded in Hamelin Bay on Western Australia’s southern coast.

In an effort to curb the population of invasive Atlantic sea lampreys (Petromyzon marinus) in the North American Great Lakes, researchers are now testing a “love trap” in northern Michigan.

Criminal gangs are becoming a growing problem in Adelaide, Australia, but unlike most other gangs, these criminals are not fighting over drugs, precious stones or illegal firearms – they’re in it for the fish.
