“…Since the mid-1990s, an integrated approach to controlling production of SMR sea lampreys has been followed (Schleen et al 2003;Siefkes et al 2013). The approach has included trapping of adult sea lampreys during spawning migrations, release of sterilized male sea lampreys onto spawning grounds, and, since 1999, application of granular Bayluscide (a selective larvicide that targets sea lamprey larvae; Dawson 2003) to selected SMR larval rearing habitats. In the late 1990s, a DA was conducted to evaluate performance of different control policies in achieving a long-term, cost-effective control program for SMR sea lampreys.…”

The St. Marys River (SMR) historically has been a major producer of sea lampreys (Petromyzon marinus) in the Laurentian Great Lakes. In the early 2000s, a decision analysis (DA) project was conducted to evaluate sea lamprey control policies for the SMR; this project suggested that an integrated policy of trapping, sterile male releases, and Bayluscide treatment was the most cost-effective policy. Further, it concluded that formal assessment of larval sea lamprey abundance and distribution in the SMR would be valuable for future evaluation of control strategies. We updated this earlier analysis, adding information from annual larval assessments conducted since 1999 and evaluating additional control policies. Bayluscide treatments continued to be critical for sea lamprey control, but high recruitment compensation minimized the effectiveness of trapping and sterile male release under current feasible ranges. Because Bayluscide control is costly, development of strategies to enhance trapping success remains a priority. This study illustrates benefits of an adaptive management cycle, wherein models inform decisions, are updated based on learning achieved from those decisions, and ultimately inform future decisions.Résumé : Historiquement, la rivière St. Marys (SMR) a été un important producteur de lamproies (Petromyzon marinus) dans le réseau des Grands Lacs laurentiens. Au début des années 2000, un projet d'analyse décisionnelle (AD) a été mené pour évaluer les politiques de contrôle des lamproies pour la SMR; ce projet suggérait qu'une approche intégrée de piégeage, de lâchers de mâles stériles et de traitements au Bayluscide constituait la politique la plus efficiente. Il concluait en outre que l'évaluation formelle de l'abondance et de la répartition des larves de lamproie dans la SMR serait utile pour l'évaluation future des stratégies de contrôle. Nous avons mis à jour cette analyse en y ajoutant des données d'évaluations annuelles des larves menées depuis 1999 et en évaluant d'autres politiques de contrôle. Les traitements au Bayluscide ont continué de jouer un rôle essentiel dans le contrôle des lamproies, mais un recrutement compensatoire élevé a minimisé l'efficacité du piégeage et des lâchers de mâles stériles dans les conditions de faisabilité actuelles. Parce que le contrôle au Bayluscide est coûteux, l'élaboration de stratégies permettant d'améliorer le succès du piégeage est une priorité. L'étude illustre les avantages d'un cycle de gestion adaptatif dans lequel les modèles éclairent les décisions, puis sont mis à jour à la lumière des apprentissages découlant de ces décisions pour ensuite éclairer de nouvelles décisions.

“…This compound is presently employed, occasionally in conjunction with a 2‐aminoethanol salt of 2′,5‐dichloro‐4′‐nitrosalicylanilide (Bayer 73), to kill larval sea lampreys in streams. Although these toxins are especially active in larval sea lampreys, they also affect other organisms (invertebrates and ancient fishes in particular; Hubert, 2003), so applications are made with great care. Only streams with large numbers of larvae ready to metamorphose are treated with TFM and then in a tightly controlled manner to avoid killing teleosts.…”

A critical review of the discovery and application of a migratory pheromone in an invasive fish, the sea lamprey Petromyzon marinus L.

The sea lamprey Petromyzon marinus, an ancient and parasitic agnathan fish native to the North Atlantic, invaded the Laurentian Great Lakes approximately a century ago triggering its fisheries to collapse. Presently, this species is held in check through a toxicant-based control programme directed by a bi-national treaty organization that seeks to develop a more broadly based integrated pest management (IPM) strategy. After a long and difficult search, the most active components of a migratory pheromone for the sea lamprey were identified and synthesized. This pheromone has remarkable potency and considerable potential to enhance various control strategies that fall within an IPM scheme. The pheromone is comprised of a mixture of at least three sulphated steroids: petromyzonamine disulphate (PADS), petromyzosterol disulphate (PSDS) and petromyzonol sulphate (PS). A steroidal sex pheromone appears to have similar promise. These discoveries, which are prompting development of the first pheromonally guided pest management programme for an invasive fish, have revealed significant scientific and policy challenges. Among the former are the needs to acquire long-term and significant support for the science, to synthesize sufficient quantities of cues, and to deploy and measure pheromonal components in natural waters. Among the latter are the needs to regulate this new type of 'pesticide', protect these technologies from exploitation and promote future research on this and other invasive fish species. Lessons from these experiences may be applicable to the study of other invasive fishes.

“…Although sea lampreys have not been eradicated from the Great Lakes, their populations were brought under control through the implementation of an integrated pest management plan Smith and Swink 2003) which included barriers to block the upstream migration of mature sea lampreys (McLaughlin et al 2007) and the release of sterile males onto spawning beds (Twohey et al 2003). The primary and most effective method of sea lamprey population control is through the application of the pesticide 3-trifluoromethyl-4-nitrophenol (TFM) to nursery streams containing larval sea lampreys (also known as ammocoetes) (Lawrie 1970;Olson and Marking 1973;Smith and Tibbles 1980;Hubert 2003;McDonald and Kolar 2007).…”

Recovery of Larval Sea Lampreys from Short‐Term Exposure to the Pesticide 3‐Trifluoromethyl‐4‐Nitrophenol: Implications for Sea Lamprey Control in the Great Lakes

et al. 2012

For over 50 years, invasive sea lamprey Petromyzon marinus populations have been controlled in the Great Lakes using the pesticide 3-trifluoromethyl-4-nitrophenol (TFM), which is applied to streams containing larval sea lampreys. The specificity of TFM is due to the sea lamprey's relative inability to detoxify it using glucuronidation; this inability causes death by interfering with the production of ATP, the main energy currency of cells. TFM treatments typically last 12 h, but given the sea lamprey's relative inability to detoxify TFM we predicted that TFM-induced homeostatic disturbances and toxicity would occur following shorter periods of exposure. Accordingly, we exposed larval sea lampreys to the 12-h LC99.9 (i.e., the concentration lethal to 99.9% of the test subjects over 12 h) of TFM for 4 or 6 h and monitored the survival and replenishment of energy stores and metabolite concentrations in surviving sea lampreys over a 24-h depuration period. Minimal mortality (∼20%) was observed during the post-TFM recovery, despite respective 50% and 70% reductions in brain and liver ATP, 70-90% decreases in brain phosphocreatine (PCr), and 30-50% reductions in brain and liver glycogen with corresponding increases in lactate. While relatively resistant to TFM, muscle still underwent a 55% decline in PCr. However, energy stores and metabolites returned to preexposure levels 4-12 h after TFM exposure. We conclude that sea lampreys can rapidly restore homeostasis following shorter-term TFM exposure. The resilience of sea lampreys to shorter-term TFM exposure suggests that there is no merit in reducing TFM treatment times from 12 h, which could lead to "treatment residuals" that survive lampricide treatments. This capacity to reverse TFM-induced perturbations also suggests that larvae seen emerging from the stream substrate late in a treatment, or that find refuge near streambanks or in isolated pools, could be another source of treatment residuals, leading to increased sea lamprey parasitism of sport and commercial fisheries in the Great Lakes.
