8:35 John Ford, resident KW foraging ecology What may have caused the simultaneous declines in the N and S residents during the late 1990s? Nutritional stress? We compared expected and observed births and deaths, where expectations were based on period of unlimited growth (’73-’90). There were two phases of increased mortality in adult/juvenile fe/males: late [...]
14:55 Val Veirs giving Marla’s talk on “Vocal Compensation in SRKWs” Background noise levels had mean of 110.1 DB +/- 4.1; range 98-123dB Call source level: mean of 55.3dB +/-7.4 dB Lombard effect in SRKWs is present; ~1dB increase in S1 call source level for every 1dB increase in ambient noise level ambient noise increases [...]
First there was Mike Bigg. Early census effort started in 1976 and was motivated by concern about the captures for aquariums which took out about 50 animals. 1976-1984 habitat use was very similar to current critical habitat! Most encounters May-October, with J pod present year-round. Ken and Mike worried about how to ID babies. They [...]
10:00 Lynne Barre, NWFSC Critical habitat can be modified. A future step is designating habitat outside of the inland waters of WA. Recovery plan implementation was started in 2003, well before the endangered listing in 2005. Proposed regulations are under review… no date given for when rule-making will occur. Consultations regarding potential impacts result in [...]
Just got an exciting email from Dr. Marla Holt, bioacoustician on the NOAA cruise that aims to understand how the southern residents utilize the outer coast of Washington. They departed last Monday and are scheduled to return April 9th, making for a significantly longer cruise than in past years. Since big ocean-going research boats like [...]
Here’s an opportunity to act (at least symbolically) for resident orca and WA salmon by reducing electricity (mostly from hydropower) demand for a special hour: 8:30-9:30pm this Saturday, March 28. On March 28 you can VOTE EARTH by switching off your lights for one hour. The results of the election are being presented at the [...]
The most prominent appeal in this discussion was whether we can move away from litigation and towards more collaborative processes to restore the wild populations of Columbia salmon and steelhead. The agreement between 3 tribes and federal agencies (the “Columbia Basin Accords”) may be a step in the right direction. However, many feel the 2008 [...]
Just happened upon this nice synopsis of how WDFW views the various processes by which fishing harvests are governed in the Pacific Northwest. For me, this helps clarify which processes we killer whale advocates could influence to bolster the number of salmon and other fish that are available to feed the southern residents. As usual, [...]
An awareness seems to be dawning that salmon smolt mortality is increased by human activities — both in the nearshore environment and in river systems. A recent biological opinion regarding Sacramento salmon suggested that about 8% of the smolts entering the San Juaquin / Sacramento delta make it through to the ocean. This article mentions [...]
Here we are in mid-February, a couple weeks into the blackmouth opening in the Salish Sea, and WDFW is opening up recreational fishing for spring (winter?) Chinook running in the Columbia [see today's email announcement below]. This makes me wonder where the southern residents are at the moment and what the run timing looks like [...]
