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 ...

Development of new methods to assess invertebrate immunology and immunotoxicology in aquaculture: oysters and lobsters as examples
In order to support healthy aquaculture, we developed assays to assess immune functions and their susceptibility to environmental conditions or toxicants. Flow cytometry allowed the rapid and quantitative analysis of oyster and lobster cell subpopulations and their functions (phagocytosis, peroxide production, natural killer cell-like activity and apoptosis). We demonstrated experimentally that ...

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 ...

State of the Art Information on Mangrove Ecosystems in Indonesia
Status and Trends of Mangroves in Indonesia GENERAL CONDITION OF MANGROVES IN INDONESIA Indonesia is a tropical archipelago with coastlines measuring a total length of 95,181 km, making it the country with the fourth longest coastline in the world (EarthTrends WRI, 2003, and Rompas, RM.2009). All along the coast are the estuaries of rivers great and small that flow the whole year round ...

Benzoylurea pesticides used as veterinary medicines in aquaculture: Risks and developmental effects on non‐target crustaceans
Diflubenzuron and teflubenzuron are benzoylureas that are used in aquaculture to control sea lice. Flubenzurons have low toxicity to many marine species such as fish and algae, but by their nature are likely to have significant adverse effects on non‐target species such as crustaceans and amphipods. Although the exact mechanism of toxicity is not known, these compounds are thought to inhibit ...

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 ...

Does one of the world’s most abundant animals need protection from our appetite?
As demand grows and habitat disappears, scientists ponder tighter controls on the Antarctic krill harvest. Barely longer than your thumb, weighing under an ounce and nearly translucent, delicate crustaceans known as krill are vital to ocean ecosystems around the world. In the waters that encircle Antarctica, krill are an essential food source for penguins, baleen and blue whales (which can eat ...

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 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 ...

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 ...

Affects of Viral Disease in Shrimp Farming
In Shrimp Disease control, they are Six viruses were known to affect Penaeid shrimp, but there are more than 20 viruses were identified as having affected wild stocks and commercial production. The OIE now lists seven viral diseases of shrimp in the Aquatic Animal Health Code, which are considered to be transmissible and of significant socio-economic and/or public health importance. These ...
