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 ...

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 ...

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 ...

Sustainable Alternatives of Shrimp Aquaculture
Early Sustainable Aquaculture Aquaculture traces its roots back thousands of years. Local farmers and fishers have cultured fish, mollusks, and crustaceans for generations, using traditional methods and local ingenuity to improve their living conditions through low-intensity aquaculture. Though these systems produced low yields, production was sufficient to meet the needs of local residents. ...

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 ...

Biological water treatment in aquaculture by means of “Mutag BioChip™ RAS Process“
Aquaculture or fish farming means the artificial breeding and raising of aquatic creatures. They include fish as well as crustaceans and shellfish, which are raised and stocked under controlled conditions by using techniques and technologies offering an increased level of productivity which cannot be realized under natural conditions. Due to the increased demand for freshly caught fish and ...

Fish Feed Extruder Machine In Aquatic Food Pellet Production
There are two types of aquatic food pellets commonly sold for farming fish or other aquatic species. The pellets have enough density to allow them to sink into the water, which is necessary for crustaceans or bottom-feeding fish, or they have a reduced density to allow them to float on the surface of the water. Floating fish feed pellets are usually produced by floating fish feed pellet machine ...

How To Produce Fish Feed Pellets With A Proper Density
Fish digestive system is very short and that is why fish feed must be light. Both dimensions and shape of fish feed pellets must be adjusted to size of fish. Besides, in water pellets must behave according to habits of fish: sink or float on surface of water. And this feature of feed depends on pellet density. Fusmar fish feed mill machine can make kinds of pellets. Kinds Of Feed Pellets For ...
