Krill and Osmoregulation - Case Study
One of the most frequent uses of krill is in special diets, when salmonids are transferred from fresh to sea water. This is due to the osmoregulating properties of krill. Krill is rich in trimethylamine oxide (TMAO) which is a known osmoreguator. The high salt content of the environment represents a strong physiological challenge for fish and crustacean. They need to keep their hemodinamic and a ...

The Blob Returns
In the autumn of 2013, Nicholas Bond, who was then the State Climatologist for the state of Washington, first detected a large (500 miles wide x 300 feet deep), circular body of sea water which had not cooled as expected and was 2 to 3 degrees warmer than the rest of the surrounding Pacific Ocean. By mid-2014, this unnaturally warm patch of ocean had grown to 100 miles long x 1000 miles wide x ...

The Role of Mangroves in Fisheries Enhancement
In 2011 humans caught and consumed 78.9 million tonnes of fish, crustaceans, molluscs and other species groups from the world’s oceans, accounting for 16.6% of the world’s animal protein intake (FAO 2012). This is projected to increase further, to over 93 million tonnes by 2030 (World Bank 2013). Global demand for fish products has increased dramatically over recent decades. Fishing ...

Krill as a Taste Attractant - Case Study
Both fish and crustaceans live in an immersed aquatic environment, where their chemioperceptive system receives permanent stimulation by soluble compounds. These substances are usually of low molecular weight, non-volatile and most of them contain nitrogen (amino acids, nucleotides, etc.). These compounds stimulate the chemioperception of the animal (taste and smell), and its behavior (feeding ...

Krill as a Source of Minerals - Case Study
Krill has a low content of ash making ideal for fresh water feeds. It is lower in content of phosphorus than other marine based meals such as shrimp or fish meal. Its calcium/phosphorus ratio is near to 1,5:1 which favors the absorption of both minerals, and it is significantly lower compared to fish or crustacean meals (3 or ...
