Species distribution models are valuable tools in studies of biogeography, ecology, and climate change and have been used to inform conservation and ecosystem management. However, species distribution models typically incorporate only climatic variables and species presence data. Model development or validation rarely considers functional components of species traits or other types of biological data. We implemented a species distribution model (Maxent) to predict global climate habitat suitability for Grass Carp (Ctenopharyngodon idella). We then tested the relationship between the degree of climate habitat suitability predicted by Maxent and the individual growth rates of both wild (N = 17) and stocked (N = 51) Grass Carp populations using correlation analysis. The Grass Carp Maxent model accurately reflected the global occurrence data (AUC = 0.904). Observations of Grass Carp growth rate covered six continents and ranged from 0.19 to 20.1 g day−1. Species distribution model predictions were correlated (r = 0.5, 95% CI (0.03, 0.79)) with observed growth rates for wild Grass Carp populations but were not correlated (r = −0.26, 95% CI (−0.5, 0.012)) with stocked populations. Further, a review of the literature indicates that the few studies for other species that have previously assessed the relationship between the degree of predicted climate habitat suitability and species functional traits have also discovered significant relationships. Thus, species distribution models may provide inferences beyond just where a species may occur, providing a useful tool to understand the linkage between species distributions and underlying biological mechanisms.

“…For example, predatory species, such as northern pike (Esox lucius) have significant impacts on fish community composition (He and Kitchell 1990). Other fish species have been shown to alter the habitats in which they live, from herbivorous grass carp (Ctenopharyngodon idella) modifying aquatic vegetation (Wittmann et al 2014) to flannelmouth characin (Prochilodus mariae) influencing sedimentation rates in Andean streams (Flecker 1997).…”

The social, economic, and environmental importance of inland fish and fisheries

Though reported capture fisheries are dominated by marine production, inland fish and fisheries make substantial contributions to meeting the challenges faced by individuals, society, and the environment in a changing global landscape. Inland capture fisheries and aquaculture contribute over 40% to the world's reported finfish production from less than 0.01% of the total volume of water on earth. These fisheries provide food for billions and livelihoods for millions of people worldwide. Herein, using supporting evidence from the literature, we review 10 reasons why inland fish and fisheries are important to the individual (food security, economic security, empowerment), to society (cultural services, recreational services, human health and well-being, knowledge transfer and capacity building), and to the environment (ecosystem function and biodiversity, as aquatic "canaries", the "green food" movement). However, the current limitations to valuing the services provided by inland fish and fisheries make comparison with other water resource users extremely difficult. This list can serve to demonstrate the importance of inland fish and fisheries, a necessary first step to better incorporating them into agriculture, land-use, and water resource planning, where they are currently often underappreciated or ignored.Key words: food security, freshwater ecosystems, importance of fish, inland fisheries.Résumé : Bien que la capture de poissons rapportée par les pêcheries soit dominée par la production marine, les poissons et les pêcheries de l'intérieur des terres apportent des contributions substantielles pour rencontrer les défis rencontrés par les individus, les sociétés et l'environnement dans un paysage en changement global. Les captures des pêcheries de l'intérieur et l'aquaculture contribuent à la hauteur de 40 % à la production mondiale rapportée pour les poissons à nageoires, à partir de moins de 0,01 % du volume total de l'eau sur terre. Ces pêcheries fournissent de la nourriture pour des milliards et un moyen de subsistance pour des millions de gens, partout au monde. Dans cette revue, en utilisant des preuves venant de la littérature, les auteurs examinent 10 raisons pour lesquelles, les pêcheries et les poissons de l'intérieur sont importants pour les individus (sécurité alimentaire, sécurité économique, l'autonomisation), pour la société (services culturels, services récréatifs, santé humaine et bien-être, transfert de connaissances et capacité à construire) et pour l'environnement (fonction écosystémique et biodiversité, comme « canaris » aquatiques, pour le mouvement « aliments verts »). Cependant, les limitations actuelles pour évaluer les services fournis par les poissons et les pêcheries intérieures rendent les comparaisons avec les autres utilisateurs de la ressource en eau extrêmement difficile. Cette liste peut servir à démontrer l'importance des poissons et des pêcheries de l'intérieur, une première étape essentielle pour mieux les incorporer avec l'agriculture, l'utilisation du territoire e...

Grass Carp Ctenopharyngodon idella stocking in the upper Colorado River basin is statutorily limited to triploid, i.e., functionally sterile, individuals. Systematic fish sampling in the upper Colorado River basin indicates adult Grass Carp remain rare but have been increasing in abundance since 2007. Grass Carp larvae collected in the Colorado River arm of Lake Powell, about 26 km downstream from the inflow, in 2015 and 2016, are evidence of the presence of a spawning population. These larvae were the first documentation of Grass Carp spawning in a river basin of the western United States. While Grass Carp reproductive biology suggests spawning occurred in the Colorado River or its tributaries upstream from Lake Powell, the sample location, age, and number of larvae collected pose the possibility of reservoir spawning. Addition of another, reproductively viable, nonnative, fish species to the already heavily invaded upper Colorado River basin could further impact conservation of the federally endangered native fishes.
