In order to be prepared for any scenario, we are currently exploring what it would take to provide such care. We are trying to help them by addressing the threats they face. The following are questions and answers about the J50 emergency response. Populations of some salmon stocks are now more abundant than they were in the 1960s, before the four lower Snake River dams were built. Under what circumstances would you consider capturing J50? SeaWorld and our other partners responded according to their expertise, providing support when and where it was asked. Finally, fishermen in the Pacific Northwest and across the nation are among the greatest advocates for salmon protection and recovery. The lack of a sustained recovery and ongoing decline since 2001 may reflect a lower carrying capacity, but many researchers are concerned that human activities and impacts, in addition to those that may have contributed to a decline in carrying capacity, may have prevented the population from fully recovering and are causing the population decline seen in recent years. SeaWorld has not been involved in captures in nearly 40 years and is committed to helping protect wild whales. Visit www.bewhalewise.org for details. We learned a great deal from A73 (also known as Springer), a young female Northern Resident killer whale that became separated from her pod in Puget Sound in 2002. The Washington Department of Fish and Wildlife (WDFW) operates many hatcheries in the Puget Sound region, some with federal funding, and is pursuing this option. As urgent as J50’s condition is, we must constantly consider the well-being of the pod as a whole. NOAA Fisheries and numerous partners have collaboratively developed recovery plans for endangered and threatened salmon and steelhead that outline strategies on all fronts to promote their recovery, and eventual delisting from the Endangered Species Act. Fisheries managers consider the needs of Southern Resident killer whales before commercial fishing catch limits are authorized. In August 2018, an international team of biologists began response efforts for J50, a member of the Southern Resident killer whale population. Internet Explorer lacks support for the features of this website. Therefore, considerations of family bonds and stress on the other pod members were not a factor in A73’s case. NOAA Fisheries, with our partners, are giving thorough consideration to all response scenarios and possible consequences of each. Veterinarians prescribed treatment, including antibiotics and a dewormer to eliminate parasitic worms thought to be an extra burden on her system, and A73’s appetite and condition improved. More information on J50 and the status of response efforts can be found on our J50 webpage. Also important is reducing vessels and noise that can make it difficult for the whales to use echolocation to find food, which can counteract the many efforts to improve the abundance of fish populations. The main contaminants of concern are PCBs (e.g., found in plastics, paints, rubber, and electrical equipment), DDT (found in pesticides), and PBDEs (fire retardant chemicals found, for example, in mattresses, TVs, toasters).
During times of nutritional stress, the effects of the high levels of contaminants in this top predator can compromise their health by impairing immune function and interfering with reproduction.
Each matriline consists of a female, her sons and daughters and the offspring of her daughters; averaging anywhere from one to seventeen individuals and one to five gener… All are managed using strict regulations that help ensure we're balancing the needs of people, the whales, and other marine life.
During times of nutritional stress, the effects of the high levels of contaminants in this top predator can compromise their health by impairing immune function and interfering with reproduction. Responders from NOAA Fisheries and partner organizations explored options ranging from no intervention to providing medical treatment and prepared contingency plans to potentially rescue her and provide short-term care in the event she stranded or separated from her pod. Can you breach the Snake River dams to provide the whales with more salmon? We will add more comments/questions and responses to this page on an ongoing basis. SeaWorld’s support helped supply expertise and resources that the team needed to best help J50.
The following are questions and answers about the J50 emergency response. These plans include safer passage for fish around dams, extensive restoration of important rearing habitat, science-based improvements in hatchery operations, and adjustments in harvest.
