“…Elsewhere, a synthetic pyrethroid, named Baythroid, at 25 µg/L was evaluated against F. rusticus and shown to be effective both in a pond and in laboratory tests [116]. Natural pyrethrum, directly affecting the physiology of crayfish, has been tested to control P. clarkii in an Italian rural district, but further experiments are needed, as claimed by authors [117]. High, sub-lethal concentrations of metolachlor (80 ppb) may interfere with the olfactory-mediated behaviour of F. rusticus to receive or respond to social signals and thus affect certain agonistic behaviours, implications that might be useful in its management [118].…”

Detection and Control of Invasive Freshwater Crayfish: From Traditional to Innovative Methods

et al. 2019

Invasive alien species are widespread in freshwater systems compared to terrestrial ecosystems. Among crustaceans, crayfish in particular have been widely introduced and are considered a major threat to freshwater ecosystem functioning. New emerging techniques for detecting and controlling invasive crayfish and protecting endangered native species are; thus, now highly desirable and several are under evaluation. Important innovations have been developed in recent years for detection of both invasive and native crayfish, mainly through eDNA, which allows for the detection of the target species even at low abundance levels and when not directly observable. Forecasting models have also moved towards the creation of realistic invasion scenarios, allowing effective management plans to be developed in advance of invasions. The importance of monitoring the spread and impacts of crayfish and pathogens in developing national data and research networks is emphasised; here “citizen science” can also play a role. Emerging techniques are still being considered in the field of invasive crayfish control. Although for decades the main traditional techniques to manage invasive crayfish were solely based on trapping, since 2010 biological, biocidal, autocidal controls and sexual attractants, monosex populations, RNA interference, the sterile male release technique and oral delivery have all also been investigated for crayfish control. In this review, ongoing methodologies applied to the detection and management of invasive crayfish are discussed, highlighting their benefits and limitations.

“…Another common practice to eradicate or control crayfish populations is with biocide, the most used being the application of xenobiotics, organophosphate, organochlorine, and pyrethroid insecticides (Cecchinelli et al, 2012). Chemical methods, however, were found to be ineffective because of their selective efficiency, with individual crayfish being differentially affected depending on size.…”

Red swamp crayfish: biology, ecology and invasion - an overview

-Alien species have been transported and traded by humans for many centuries. However, with the era of globalization, biological invasions have reached notable magnitudes. Currently, introduction of alien species is one of the major threats to biodiversity and ecosystem functioning. The North American crayfish Procambarus clarkii is one of the most widely introduced freshwater species in the world, especially due to its high economic importance. It is responsible for great modifications in invaded environments causing irreparable ecological and economic damages. Its impressive ability to successfully colonize a wide range of environments is a consequence of its behavioural and biological characteristics that can adapt to features of the invaded location, conferring to this species a notable ecological plasticity. This review summarizes the available information regarding P. clarkii's biology and invasive dynamics around the world in order to contribute to the understanding of the threats posed by its establishment, as well as to support management and impact mitigation efforts.

“…For a species to be invasive, it must be able to establish growing populations outside its native range (Colautti & Richardson, 2009;Gherardi et al, 2011). Different strategies have been developed to address and mitigate invasions in each step of the process (Shigesada & Kawasaki, 1997;Williamson, 1999;Cassey et al, 2004;Gherardi et al, 2011;Cecchinelli et al, 2012), but measures adopted for established populations are more problematic and expensive (Bax et al, 2001;Hulme, 2006). Therefore, the assessment of environmental conditions under which the species has a positive population growth rate could be valuable, indicating areas where conservation efforts to prevent and/or contain an invasion would be most relevant (Peterson, 2003).…”

Niche conservatism and the potential for the crayfishProcambarus clarkiito invadeSouthAmerica

Summary Invasive species are one of the most severe threats to biodiversity, and an ability to predict the extent of potential invasions can help conservation strategies. Species distribution models (SDMs) have been widely used to project the potential range of invasive species. These models assume that species retain their niche properties during invasion (niche conservatism), although this assumption is seldom verified. We gathered occurrence records for the crayfish Procambarus clarkii from the U.S.A. and Mexico (native + invasive ranges) and from the Iberian Peninsula (invasive) to test for niche conservatism across continents using niche overlap metrics (Schoener's D). To test for differences in the climate space occupied by the species on the different continents, we performed two principal component analyses (PCAs) on the environmental data extracted from occurrence records: first, separately for each occurrence data set (i.e. each continent) and secondly, using the pooled data. Subsequently, we projected the model to South America, where this species has the potential to become invasive. Schoener's D showed high overlap (0.68) between the two regions (the Americas and Iberia), and there was no difference between the regions in both PCAs. The crayfish has conserved its niche across continents, and therefore, our model projection to South America may accurately demonstrate where invasion is most likely to occur. Large parts of South America are apparently suitable, mainly Argentina, Chile, Paraguay, Uruguay and southern Brazil. This result is of great concern since this invasive species can spread quickly in suitable areas. Stronger laws and regulations should be made to protect native biodiversity and agricultural land. Our approach could be replicated for the study of invasions by other species where extensive data on the potentially invaded areas are available.

Use of natural pyrethrum to control the red swamp crayfish Procambarus clarkii in a rural district of Italy

Abstract: Experimental evidence is provided for the efficacy of Pyblast to control invasive crayfish. Obviously, before its use on a large scale, further studies are needed to find a concentration that will achieve the target 100% mortality with the shortest recovery time of the environment.
