Adsorption isotherm of uranyl ions by scales of Corvina fish
Fish scale is a by-product of fishery. The scales are mainly formed by hydroxyapatite and collagen, forming a kind of natural composite with a large specific surface area that intensifies the adsorption process. In this paper, the potential of adsorption of scales of Corvina fish for uranyl ions from nitric solutions was studied. Equilibrium and kinetic studies in adsorption of uranyl ions in ...

Drying Sardine Fishes by Microwave Drying Machine
1. Why Fresh Sardine Fishes Need to Be Dried by Microwave Drying Machine? Sardine fish is an important source of high-quality protein required in human diet, but it has not yet been fully utilized, due to the limited storage period and, sometimes, their strong fishy odor. Fresh sardine fish contains up to 80% of water, and it is a highly perishable material and having a short storage life. ...

Moving Up the Food Chain
For most of the time that human beings have walked the earth, we lived as hunter-gatherers. The share of the human diet that came from hunting versus gathering varied with geographic location, hunting skills, and the season of the year. During the northern hemisphere winter, for instance, when there was little food to gather, people there depended heavily on hunting for survival. Our long history ...

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 ...

How to make fish feed pellet
Manufactured feeds is produced by feed pellet machine ,which is an important part of modern commercial aquaculture, providing the balanced nutrition needed by farmed fish. The feeds, in the form of granules or pellets, provide the nutrition in a stable and concentrated form, enabling the fish to feed efficiently and grow to their full potential. The nutritional content of feed pellet can not ...

New Study Findings about Fish Gene Editing
Spermatogonial stem cells (SSCs) are a type of reproductive stem cells with self-renewal and differentiation potential in adult male gonads. Using spermatogonial stem cell transplantation (SSCT) technology, it is possible to achieve cross-individual or even cross-species "parthenogenesis", that is, the use of individual (or species) B to produce functional gametes of individual (or species) A. ...

Expanding marine protected areas to restore fisheries
After World War II, accelerating population growth and steadily rising incomes drove the demand for seafood upward at a record pace. At the same time, advances in fishing technologies, including huge refrigerated processing ships that enabled trawlers to exploit distant oceans, enabled fishers to respond to the growing world demand. In response, the oceanic fish catch climbed from 19 million tons ...

Fish Farmers Can Produce Fish Feed Pellets Themselves In Nigeria
Nigeria is one of the leading producers of catfish in Africa. But this has been grossly inadequate to meet WHO’s protein requirement recommendation per person. This is made up by imports from Europe, South America, and the Far East. That is unnecessary while using the Minister of agriculture’s assertion that Nigeria’s aquaculture industry has the potential to serve the whole of ...
