[2] The vaquita is at risk of extinction due to its small population size. }, Predators include cookie-cutter sharks, as evidenced by bite marks seen on a number of Northern fishing fleets have had an indirect positive impact mainly on marine mammals, because fishing on predators like sharks reduces its predatory negative impact on those groups. Strandings in 2011 for Mississippi and Alabama were 5 times and 4 times the 2002-2009 historical average respectively. This means the Gulf SEFHIER program is currently not in effect. For the entire year in 2010, there were 139 strandings in Louisiana, including 48 strandings prior to theDeepwater Horizonoil spill. This competition is evidenced by the presence of sexual dimorphism (females are larger than males), small group sizes, and large testes (accounting for nearly 3% of body mass). The Gulf states continue to use the testing protocol to routinely test finfish and shellfish that are caught in state waters.

Clymene dolphin For starters, they both have incredibly complex brains, which is why both dolphins and porpoises are so intelligent. Although the predation of sharks towards vaquita do result in a decline in population and is seen as an alternate threat, northern fishing fleets also negatively impact this small marine mammal because the negative influence of incidental catch is greater than the positive influence of predation reduction by shark fisheries. The few remaining females could die during capture, dooming the species. Dolphin strandings have also remained elevated in Mississippi and Alabama in 2010 and 2011.

During the NOAA testing programs existence, sensory and chemical testing methods were used to measure polycyclic aromatic hydrocarbons (PAH) and dispersants in more than 8,000 seafood specimens collected in federal waters of the Gulf of Mexico. When detected, the PAH concentrations were at least two orders of magnitude lower than the corresponding FDA level of concern for each PAH. "name": "Dolphinaris" [31][pageneeded] It was approximated at one point that there were 150 individuals left with a 10% annual decline within their population[21] Anthropogenic effects of a rise in commercial fishing such as accidental bycatch, illegal fishing, and entanglement have been linked to the cause of their decline.

So, of course, when they find out that they are two totally distinct species, they're often surprised. Because of their small population size, vaquitas are experiencing a negative Allee effect, attributing to even smaller population growth rates, driving them further into extinction. Porpoise vs Dolphin | Sea Creatures | Marine Conservation [7][8][failed verification] Genome sequencing from an individual captured in 2017 indicates that the ancestral vaquitas had already gone through a major population bottleneck in the past, which may explain why the few remaining individuals are still healthy despite the very low population size.
