  • The secret life of the sea trout
    Sea trout, also known as brown trout, live complicated lives. Like salmon, they begin their lives in a river, hatched from eggs that were laid in small nests, called redds. As the young fish mature, they go through several developmental stages, all of which involve substantial physiological changes. The most important stage from this perspective is when the fish becomes a smolt, after about 2 years. Entering the smolt stage is like being given a passport out to the sea, because the physiological changes allow the fish to tolerate salt water.
  • Fish 'personality' linked to vulnerability to angling
    Individual differences in moving activity in a novel environment are linked to individual differences in vulnerability to angling, according to an experimental study. The study used novel, long-term observations of individual behavior in groups and authentic angling trials to analyze if behaviors predict the vulnerability to fishing in brown trout reared in traditional and enriched hatchery rearing environments. Based on the results, it can be predicted that fishing modifies the heritable behavioral traits of fish by favoring cautious fish.

Ethan Daniels

ethan_danielsFollowing a recent trip to the Dominican Republic, Photojournalist and Underwater Photographer Ethan Daniels has provided ReefID with some fantastic shots of Humpback Whales (Megaptera novaeangliae) to add to the database.


img_837816835The Humpback Whale is one of the largest species of baleen whales ranging from 12-16 meters and weighs approximately 36,000 kilos.  It is an extremely acrobatic animal that often breaches and slaps its tail making it extremely popular with whale watchers.

 
Found in oceans and seas around the world, the humpback is a traveler.  They typically migrate up to 25,000 kilometers from polar waters where they feed in the summer to tropical or sub-tropical waters to breed and give berth in the winter.

 

Ethan uses his extensive background in marine biology and photography to lead informative and fun trips to see these majestic animals as well as many other fantastic creatures through Wilderness Travel.  He has also produced the books "Under Cape Cod Waters" and "Coral Triangle Seascapes" along with his personal website www.oceanstockimages.com .
