BILL ANALYSIS Ó AB 165 Page 1 Date of Hearing: April 16, 2013 ASSEMBLY COMMITTEE ON WATER, PARKS AND WILDLIFE Anthony Rendon, Chair AB 165 (Gaines, Beth) - As Introduced: January 23, 2013 SUBJECT : Commercial fishing: crayfish SUMMARY : This bill lifts the ban on sale and purchase of crayfish taken from Lake Tahoe or the Lake Tahoe Basin and includes both legislative findings and guidelines for any prospective regulations authorizing commercial crayfish harvesting in Lake Tahoe or the Lake Tahoe Basin. Specifically, this bill : 1)Deletes the Fish and Game Code section barring the sale or purchase of crayfish taken from Lake Tahoe or the Lake Tahoe Basin. 2)States that it is the intent of the Legislature that any commercial taking of crayfish from Lake Tahoe or the Lake Tahoe Basin be for the primary purpose of reducing and controlling the crayfish population. Further states legislative intent that commercial taking of crayfish be allowed only as is consistent with state goals for management of invasive species and with state environmental standards. 3)Requires the Fish and Game Commission (Commission) to ensure that its regulations for the taking of crayfish from Lake Tahoe or the Lake Tahoe Basin for commercial purposes be consistent with the Lake Tahoe Region Aquatic Invasive Species Management Plan. EXISTING LAW 1)Since 1970, prohibits the sale or purchase of crayfish taken from Lake Tahoe or the Lake Tahoe Basin. 2)Requires commercial fishing licenses, crayfish permits, and commercial fishing vessel registration for commercial crayfish harvest operations. Limits the size of crayfish traps to three feet in greatest dimension and requires the immediate return of other species taken in crayfish traps. 3)Confers authority to the Commission to set regulations for the AB 165 Page 2 take and possession of crayfish and to prohibit the use of crayfish traps that will injure fish or create "unnecessarily large" amounts of bycatch. 4)Under regulations promulgated by the Commission, prohibits the take of crayfish for commercial purposes from all lakes and reservoirs and limits take in certain California counties, including Placer and El Dorado Counties, to areas west of Highway 49. Further requires that crayfish legally caught under a commercial license be used only for human consumption or for aquaculture. FISCAL EFFECT : Unknown COMMENTS : Legislative History: Why is a commercial crayfish fishery in Lake Tahoe banned? : In the late 1960's, a researcher from Sweden named Dr. Sture Abrahamsson came to the United States to conduct ecological research on the crayfish in Lake Tahoe. During his research, he worked with Dr. Charles R. Goldman, a noted limnologist at the University of California, Davis (UC Davis), on a project aimed to protect the future of Lake Tahoe. On behalf of the Swedish Fisheries Board and with full consent and knowledge of the California Department of Fish and Game, Dr. Abrahamsson also collected approximately 100,000 crayfish. The stated purpose of the crayfish collection was not only ecological research but also export to Sweden to reestablish the crayfish population following a deleterious fungus outbreak. The crayfish from Lake Tahoe, estimated to number over 55 million adults at that time, were immune to this fungus and were, therefore, an ideal replacement stock. Despite the researchers' and state agencies' understanding, rumors abounded that this large extraction of crayfish was for commercial purposes. In January of 1970, Assembly Member Eugene A. Chappie introduced AB 465, which created the existing law at Fish and Game Code section 8490 banning the buying or selling of crayfish from Lake Tahoe or the Lake Tahoe Basin. Assembly Member Chappie soon thereafter sent a letter to Dr. Goldman inquiring about the recent removal of a large number of crayfish from Lake Tahoe. The Department of Fish and Game, Dr. Goldman, and Dr. Abrahamsson responded with letters assuring that crayfish were only taken from Lake Tahoe for the permitted AB 165 Page 3 purposes of ecological research and limited export to Sweden. These letters apparently did not ease concerns about the potential depletion of Lake Tahoe's crayfish by domestic and foreign commercial operations. AB 456 ultimately became law. Species and Ecological Background : The signal crayfish (Pacifastacus leniusculus) is native to freshwaters within the Pacific Northwest coast. The Truckee watershed was first seeded with crayfish in the early 1900s. Some of the crustaceans were planted by anglers to provide food for the trout deposited in Lake Tahoe in the late 1800's, and some were most likely planted as a food source for locals. For years, crayfish were a dietary staple for nonnative trout and kokanee salmon in Tahoe, and the signal crayfish population was kept relatively under control. In the 1960's, researchers from UC Davis estimated that there were 56 million crayfish in Lake Tahoe. However, around the same time as the crayfish controversy and the resulting ban on commercial crayfish harvesting, a species of shrimp (Mysis relicta) was released into Lake Tahoe. With the opportunity for easier prey, the fish began feeding on the shrimp instead of the newly protected crayfish. In 2001, a different group of scientists estimated that the crayfish population had increased to 220 million. The author's background materials estimate that there are now 240 million crayfish in Lake Tahoe, and news articles have placed this number as high as 280 million. The dramatic crayfish population growth over the past half century has been attributed to decreased predation due to the shift in the lake trout's diet. Climate warming may also be driving crayfish production. Crayfish are still a major food resource for invasive, warm water fish species, such as smallmouth bass, largemouth bass, and bluegill species. The increasing numbers of crayfish are believed to contribute to the population growth of these species. Crayfish have also been found to excrete nitrogen and phosphorus, which are important stimulators of algae production. Thus, crayfish are believed to contribute to the degradation of water clarity in the lake. Commercial Crayfish in Nevada : On the Nevada side of Lake Tahoe, commercial crayfish harvesting is authorized. Nevada had a statewide ban on the take of crayfish for commercial purposes until very recently. In 2011, the Nevada Board of Wildlife AB 165 Page 4 Commissioners amended its regulations to permit commercial take of crayfish from Lake Tahoe for an annual permit fee of $500, provided that the Nevada Department of Wildlife approves the time, place, and manner of the operation and determines that the operation "is not deleterious to fish or other wildlife indigenous or planted or propagated in those waters at public expense." The Nevada Board of Wildlife Commissioners amended its regulations again in 2012 to explicitly allow the commercial sale of crayfish from Lake Tahoe, both by a permit holder to a food wholesaler or restaurant and by a food wholesaler to a restaurant. At least five businesses have received both commercial crayfish permits from the Nevada Department of Wildlife and commercial permits from the Tahoe Regional Planning Agency (TRPA). These businesses must also work with the U.S. Army Corps of Engineers and the Nevada Division of State Lands to obtain appropriate clearances. At this time, one business, the Tahoe Lobster Company, is harvesting crayfish from Lake Tahoe. Related Legislation : This bill is substantially similar to AB 2504 (Beth Gaines) from 2012. On April 24, 2012, the Committee heard the introduced version of AB 2504, which at that time merely proposed the repeal of Fish & Game Code 8940's ban on sale or purchase of crayfish from Lake Tahoe or the Lake Tahoe Basin. The Committee voted 13-0 to pass AB 2504 with amendments regarding legislative intent and consistency with the Lake Tahoe Region Aquatic Species Management Plan. AB 165 includes provisions nearly identical to the Committee amendments to AB 2504 from last year. Following the Committee's passage, AB 2504 was referred to the Assembly Committee on Appropriations, which ultimately voted 17-0 to pass the bill with amendments authorizing the Department of Fish and Game (now Department of Fish and Wildlife) to impose a charge upon participants to recoup the "reasonable costs of implementing and enforcing the commercial crayfish fishery." At the author's request, AB 2504 was ordered to the inactive file and, consequently, was not taken up for a vote on the Assembly floor. AB 165 Page 5 Author's Statement : The author states that this bill will help control Lake Tahoe's invasive crayfish population. The author argues that reducing the number of crayfish in Lake Tahoe will in turn help address the concerns over both lake clarity and invasive species. In addition to environmental benefits, the author states that allowing the buying and selling of crayfish from Lake Tahoe will help stimulate the state and local economy. The author notes that, under current law, even California restaurants near Lake Tahoe must import crayfish from out of the region or out of the state. Support Arguments : TRPA, the bi-state planning and regulatory agency with jurisdiction over the Lake Tahoe region, supports lifting California's current statutory ban on commercial harvest of crayfish. TRPA states that commercial crayfish harvesting from Lake Tahoe "may allow the control of this species by engaging the private sector to accomplish what otherwise would not be possible given the limited public funding" for controlling invasive species. TRPA also states that it will "conduct an environmental analysis on the commercial boating associated with each individual harvest operation" in order to ensure that any resulting commercial operation is consistent with its standards and ordinances. Other Issues for the Committee's Consideration : As noted in the Committee analysis of last year's AB 2504, removal of crayfish through commercial harvest may have both positive and negative ecological impacts. For these reasons, some fishery scientists have urged that any prospective commercial fishery involve careful planning and monitoring. A noted crayfish scientist raised several issues regarding the establishment of a responsible commercial harvesting program for Lake Tahoe, including avoidance of bycatch, avoidance of spreading signal crayfish to other ecosystems, limiting the areas of harvest to protect invertebrate habitat, maximizing cooperation among agencies and scientists, inter-agency cooperation, and tracking and analyzing commercial harvest and ecosystem data. AB 165 Page 6 This bill does not in itself authorize commercial crayfish harvest in Lake Tahoe. Nor does it require the Commission to amend its regulations to allow such commercial crayfish operations. However, given this bill's intent to remove a barrier on commercial crayfish harvest in Lake Tahoe and the Lake Tahoe Basin, as well as the State of Nevada's recent authorization of such operations, it may be appropriate to consider the potential regulatory and administrative implications of this bill. Without Fish and Game Code section 8940, the Commission would still have to amend its regulations - including those barring commercial crayfish harvest in any lake or reservoir and in Placer and El Dorado Counties east of Highway 49 - before a commercial crayfish harvest operation at Lake Tahoe would be authorized. As noted in the committee analyses of AB 2504, the Commission's amendment of its regulations would be a discretionary action potentially subject to the California Environmental Quality Act (CEQA). Pursuant to CEQA, the Commission may be required to conduct an initial study and to prepare appropriate environmental documentation based upon the potential environmental impact of the project. Additionally, the Department of Fish and Wildlife would likely have to devote additional time and resources toward designing, implementing, and enforcing any potential commercial harvest program in Lake Tahoe. Although the potential costs of a commercial crayfish program on the California side of Lake Tahoe are unknown, Nevada's commercial permit fee for crayfish in Lake Tahoe is $500. In contrast, the current commercial permit fee for crayfish in California is $41.97. REGISTERED SUPPORT / OPPOSITION : Support Tahoe Regional Planning Agency Individual(s): 1 Opposition None on file.
