Global sturgeon aquaculture production: an overview
The present total output of about 80–100 tonnes of caviar from aquaculture is now already exceeding the 2006 legal caviar yield from fisheries in the Caspian area while being close to the 2007/2008 quotas.
Present and future sturgeon and caviar production and marketing: A global market overview
The same drive that gave the incentive to farm sturgeons also provided the incentives to seek alternative products that could fill the void in caviar supplies and even create new market sectors, so the future of caviar trade will be determined mainly by demand-driven price structures.
A brief overview on the status and prospects of sturgeon farming in Western and Central Europe
This paper provides a short overview on the status of sturgeon farming in Europe, covering most of the EU and former East Block countries, including market opportunities.
Fluctuations of Zooplankton Taxa in Ballast Waterduring Short‐Term and Long‐Term Ocean‐Going Voyages
The preliminary results from sampling the ballast water of the first four oceangoing workshops of this Concerted Action showed a decrease in numbers of specimens and taxa over time.
Parasites in larvae of the herring (Clupea harengus L.) fed with wild plankton
In winter 1965/66 larvae of Downsherring were reared in aquaria at the Marine Station of the Biologische Anstalt Helgoland and about 10% of the actively feeding larvae were lost due to two endo-Parasites and two ecto-parasites.
Growth, food conversion and agonistic behaviour in common dentex (Dentex dentex) juveniles fed on pelleted moist and dry diets
The results indicate a strong relationship between nutrition, size variation and agonistic behaviour in the rearing of cornmon dentex juveniles, which is considered to be favourable for aquaculture requirements.
Inshore–offshore comparison of parasite infestation in Mytilus edulis: implications for open ocean aquaculture
Offshore mussel production could be a promising culture procedure because it seems to result in lower parasite burden than at traditional culture sites, and whether offshore production also results in better survival and growth, compared with inshore mussel culture on a commercial scale, needs to be investigated.
