Where can I find Siberian Sturgeon?

Three sub-species have been distinguished: Acipenser baerii baerii in the Ob basin, Acipenser baerii stenorrhynchus from the Ienisseï as far as the Kolyma and lastly, Acipenser baerii baicalensis in Lake Baïkal.#N#Large annual catches (as much as several hundred tonnes) were taken, in decreasing order, in the basins of the Ob, the Ienisseï and the Lena rivers at the beginning and in the middle of the twentieth century. Siberian sturgeon is a freshwater species, but it migrates long distances in the rivers where it is found. Unlike other sturgeon, the spawning stock continues to feed during the period of generative migration. Puberty occurs late, as growth is slow in these cold conditions, between 10 and 17 years for males and 12 to 20 years for females, depending on their origin. The adults of both sexes possess Muller canals. The oviduct takes up about one-third of the abdominal cavity and is linked with the Muller canal via a unidirectional valve. This species belongs to the group of sturgeons with a chromosome number of around 250.#N#The species can live in temperatures that range widely, from only 1°C to 25–26°C. It is fairly resistant to low oxygen content but does not put on weight in such conditions.

How do sturgeons produce caviar?

To produce true sturgeon caviar, some farms use hormone injections to stimulate ovulation, then remove the roe through a small repairable incision. This enables the fish to provide further eggs every two years or so throughout its lifetime, which may last decades. However, the majority of sturgeon farmers use non-ovulated eggs still in the ovarian membrane, which means they have to euthanize the fish before egg removal. This is a more traditional method and produces better caviar, according to experts.

What is the protein content of sturgeon feed?

Commercial sturgeon feed has a protein content of 44%, derived primarily from fishmeal, corn protein concentrate, soya bean meal and poultry by-product meal (Michaels pers. comm.). Ingredients that may be fit for human consumption include (the wild fish providing) the portion of fishmeal and fish oil not from by-products and some amount of protein in crop ingredients (Stoner 2012). Although producers indicate the presence of terrestrial animal meal and crop by-product, due to proprietary formulations it is unknown what percentages US sturgeon feed contain. As such, it is not possible to include these ingredients in the assessment and a conservative formula with all non-marine ingredients assumed to be edible crop. Using an average crude protein content of fishmeal of 65%, this means that approximately 10.8% of the protein in sturgeon feed comes from non-edible sources (from the 26.1% of fishmeal byproduct) and 89.2% feed protein is from edible crop ingredients (Miles & Jacob 2011).

What is aquaculture in California?

As mentioned in the Effluent criterion, aquaculture in the US operates under the governance of several federal and state laws and regulations, which are implemented by a number of federal and state agencies permitting and monitoring different aspects of production. In California, the lead agency is the Department of Fish and Wildlife (CDFW). The inland aquaculture industry in California is currently small enough that cumulative impacts are not considered (by this assessment) to be a concern; consideration will be given to the industries’ total size and concentration if growth increases (Lovell pers. comm.). Regulatory control measures prevent the siting of facilities in high-value habitats and the placement of sturgeon facilities on agricultural land may prevent it from being converted to residential or other use. The application and approval process differs depending on the location and species, but is considered suitable to prevent farm siting from reducing ecosystem function (Lovell pers. comm.). In 2005, the Public Resources Code (PRC) Section 30411(e) amended the Department of Fish and Game Code to require the preparation of programmatic environmental impact reports (PEIRs) for both coastal and inland commercial aquaculture projects. While the PEIR for inland aquaculture is currently still under development, its requirements will include systematic assessment of appropriate siting, potential impact on sensitive habitats, the cumulative effects of multiple farms and facility design to minimize impact. Under this, CDFW will be responsible to prevent or stop activities deemed damaging to the environment. The combination of the regulatory content and enforcement means that the regulatory management effectiveness score (Factor 3.2) is 6.8 out of 10.

What is the final score for sturgeon?

The final numerical score for US farmed sturgeon is 7.53, which is in the green range. All criterion scores are in the green range with the exception of Feed and Chemicals, which are yellow.

How are white sturgeon raised?

The farmed White Sturgeon is raised in exceedingly pure water. Using an ozonation process that reduces organic pollutants we ensure the fish begins its life and is raised in optimal conditions. Dissolved ozone is highly effective for nitrite reduction and algae control. We are therefore committed to promoting a very healthy habitat for the fish and its roe. Biologists feed a proportionate balance of both land and sea-based ingredients to the fish and, therefore, we generate a more sustainable food supply for wild fish and oceans. We share recycled water for different eco-friendly purposes such as creating artificial wetlands. All caviar is not alike. Our sturgeon stand out as leaders of optimal production for instance.
