“…Larvae (glochidia) are obligate, external parasites on the gills or fins of fishes and may be transported long distances while attached to the host (Strayer 2008). After the parasitic period, juvenile mussels drop off their hosts and may be transported downstream by river currents before settling to the bottom (Morales et al 2006, Daraio et al 2010. Consequently, mussel beds are presumed to be linked by dispersal of glochidia on host fishes and passive downstream drift of juveniles.…”

Local aggregations of unionoids (mussel beds) represent subpopulations constituting a riverine metapopulation and are presumed to be linked by dispersal of parasitic mussel larvae (glochidia) on host fishes. We examined movement patterns of Masu Salmon (Oncorhynchus masou masou), the obligate host fish for the freshwater pearl mussel Margaritifera laevis, during the mussel's parasitic period to determine the dispersal potential of glochidia via host fish in the Shubuto River system, Hokkaido, Japan. We conducted a mark-recapture study in a 650-m river section to describe the distance and directionality of host fish movement, and we used fyke net sampling to quantify the number of host fish moving from mainstem rivers to tributaries. Most individuals of Masu Salmon captured in the study were infected with glochidia of M. laevis. The displacement distance of infected fishes ranged from 37.5 m downstream to 512.5 m upstream (mean = 36.5 m upstream from marking location). The dispersal kernel based on a diffusion-advection model represented a leptokurtic distribution with a fat-tailed upstream bias, but most recaptured fish remained near the initial capture location. Movement of fish from mainstem rivers to tributaries was strongly affected by differences in water temperature among tributaries. Most individuals moved to cooler tributaries, but tributaries did not support populations of M. laevis. These results suggest that glochidial dispersal via host fish is important for local recruitment and upstream dispersal, but dispersal to tributaries may be a source of mortality for M. laevis.

“…It is possible to find models that use different techniques, such as diffuse, multivariate and fuzzy logic approaches, and that allow the inclusion of the interaction between ecological variables (BOAVIDA et al, 2014;BENJANKAR et al, 2012;DARAIO et al, 2010;SILVA, 2010), including water quality parameters, such as temperatures, dissolved oxygen levels, biochemical oxygen demands and nutrients (SOUZA et al, 2014;MARSILI-LIBELLI et al, 2013;AYLLÓN et al, 2012b), among other potentialities. Such models vary in complexity, from one-dimensional models (GOTO et al, 2015) to those based on two- (YI et al, 2010) or three-dimensional hydraulic equations (DARAIO et al, 2010).…”

One- And Two-Dimensional Ecohydraulic Modeling of Formoso River (Mg)

et al. 2016

ABSTRACT:The objective of this study was to compare ecohydrological simulations from a onedimensional model (PHABSIM -Physical Habitat Simulation System) and a two-dimensional model (River2D) in order to indicate a reliable tool that could be used to determine public policies for the sustainable management of the water resources of the Formoso River basin (MG). The results from the calibration of hydraulic variables, namely, water depth and velocity, as well as habitat predictions for three fish species of the river were compared. The results showed that River2D was best suited to simulate ecohydrological features for the studied river stretch. Although PHABSIM presented a better fit of the hydraulic variables at the calibration process, the use of only three monitoring cross sections to compose the biotic model database compromised its habitat modeling. PHABSIM model was not able to accurately assess the actual characteristics of the physical habitat in the segments of the river located between the monitoring cross sections.

“…Therefore, the fishes do not always return to the target site if managers succeed in habitat restoration for target fishes. Several studies have previously described models that include species dispersal (Daraio et al 2010), emigration and population dynamics (McMahon and Matter 2006), or habitat connection (Chaput-Bardy et al 2009). Although such models involving ecological information such as dispersal, emigration, and habitat connection might be required in prioritizing target sites with habitat restoration in the future, it is my hope that habitats are preferentially restored at sites with the neighboring actual habitats of target fishes at present.…”

The aim of this study was to propose a method for site selection for habitat conservation or restoration of threatened freshwater fishes inhabiting ditches or canals in the main plains of northern Kyushu Island, Japan. The environmental data of 4,084 third meshes in six regions and faunal data of 337 meshes that included 462 sites were analyzed using generalized liner mixed models, and species distribution models with high accuracies were developed for nine threatened species. Habitat conservation or restoration for each species was discriminated using gaps between actual and potential distributions. The number of species under each management was determined for each site, and the management type with a large number of species was selected (Case 1), or the target species were set for each potential faunal group based on similarities of fish fauna, and the type was selected by counting only the target species (Case 2). On the basis of the conserved sites showing actual presences, Case 2 showed higher effectiveness than Case 1. The estimated practices and successes of all habitat managements in Case 2 showed an increase of 1.3-4.6 times for actual presences, with optimal habitats reaching 78-91 % of their potential presence and conserved sites attaining 64-97 % of the actual presence of each species. In the case with special attention to the most threatened species, Acheilognathus tabira nakamurae, a small decrease in effectiveness was noted for several species.
