Omega Protein's fishing fleet takes about 90% of the menhaden harvested in US waters; the extent of its harvest has been a subject of controversy. [3] In December 2012, in the face of the depletion of Atlantic menhaden, the Atlantic States Marine Fisheries Commission imposed a limit on Omega's operations, "capping the total annual commercial catch at 170,800 metric tons, about 80 percent of ...
This was because of menhaden oil's high omega-3 fatty acid content, which took the place of omega-6 fatty acid, which is not as beneficial to animals. Another animal that benefits from omega-3 in menhaden oil is guinea pigs. When given menhaden oil in feed guinea pigs were shown to have a longer life span. [21]
Industrial machines for extracting oil mechanically are call expellers. Many expellers add heat and pressure, in order to increase the amount of oil extracted. If the temperature does not exceed 120 °F, the oil can be called "cold-pressed". [3] In modern vegetable oil production, oils are usually extracted chemically, using a solvent such as ...
The range of Gulf menhaden encompasses the entirety of the Gulf of Mexico nearshore waters, with the exception of the extreme eastern Yucatan and western Cuba. [2] Evidence from morphology [3] and DNA analyses [4] suggest that the Gulf menhaden is the Gulf of Mexico complement to the Atlantic menhaden (Brevoortia tyrannus).
Of California's total plant population, 2,153 species, subspecies, and varieties are endemic and native to California alone, according to the 1993 Jepson Manual study. [4] This botanical diversity stems not only from the size of the state, but also its diverse topographies , climates, and soils (e.g. serpentine outcrops ).

The California Floristic Province is a world biodiversity hotspot as defined by Conservation International, due to an unusually high concentration of endemic plants: approximately 8,000 plant species in the geographic region, and over 3,400 taxa limited to the CFP proper, as well as having lost over 70% of its primary vegetation. A biodiversity ...
The Santa Monica Mountains are covered by hundreds of local plant species: some are endemic or very rare, some are beautiful California native plants in situ, and some also are familiar as horticultural ornamental and native garden plants. Each season has different plants predominating the visual experience.
