For those less familiar with the Salton Sea, it is not normally thought of as a modern day recreational destination. However, the Salton Sea is a popular site for campers, boaters, anglers, hunters and more. The southern shore is home to the Sonny Bono wildlife refuge, and many state managed duck and geese blinds for waterfowl hunters. Along the north shore of the Sea, 14 miles of shoreline have been designated for recreation, known as the Salton Sea State Recreation Area (SRA). This area provides access to kayaking, boating, camping, bird watching, photography and hiking . Continue reading “Recreation at the Salton Sea”
The Salton Sea has been many things to a lot of people. It has been a piece of post-apocalyptic landscape, an artist’s muse, and a lesson on water management and habitat restoration. At one point, it was a hot spot for vacations and was even one of the hottest fisheries in California. Imagine that, the Salton Sea as it is now once had enough fish in it that you could catch them without bait. Now, not so much, but that does not mean you cannot fish at the Salton Sea. There are even groups such as the Sea and Desert Interpretive Association that advocate fishing at the Salton Sea as a wholesome means of entertainment.
So the pressing question on everyone’s mind is “Can I eat fish from the Salton Sea?” More precisely, “Will eating fish from the Salton Sea kill me?”
The first post on this topic established that the Salton Sea is an ecological oasis and one of the last existing stops in southern California for migratory birds along the Pacific Flyway. However, it was mentioned previously that there are many factors which are threatening this avian Eden. Each of these threats will be addressed in more detail individually, with the first being avian botulism toxin.
Avian botulism toxin is produced by the bacteria Clostridium botulinum. While the bacteria is commonly found in soils and wetlands, it will not produce the botulism toxin unless certain environmental conditions are met. In order for the bacteria to produce the toxin, it needs an anaerobic environment, warm temperatures, and a protein source. Do these conditions sound familiar? In the summer, low dissolved oxygen levels, high temperatures, and the presence of dead algae (protein source) in the Salton Sea provide an ideal environment for the growth of C. botulinum and the subsequent production of avian botulism toxin.

Over 400 different species of birds rely on the Salton Sea
The Salton Sea is often construed by the news, documentaries, and other blogs as a post-apocalyptic wasteland that is devoid of life. However, this is an incorrect portrayal that has taken hold, most likely for its dramatic effect. In reality, the Salton Sea and its surrounding area is an oasis of biodiversity in the Sonoran Desert. Over 400 different species of birds utilize the sea for some portion of the year . This makes the Salton Sea rank 2nd in avian diversity in the United States . In addition to the sheer number of birds that rely on the Sea, it is important to consider which species of birds are there. Continue reading “Bird is the Word”
