“…This is because many rivers have been multiple-channel rivers in the past, but they were changed to narrow, straightened rivers by human activities [2,4,[48][49][50]. However, this study is different from previous studies.…”

After Typhoon Morakot, dredging engineering was conducted while taking the safety of humans and structures into consideration, but partial stream reaches were formed in the multiple-channel sections in Cishan Stream because of anthropogenic and natural influences. This study mainly explores the distribution of each fish species in both the multiple-and single-channel sections in the Cishan Stream. Parts of the environments did not exhibit significant differences according to a one-way ANOVA comparing the multiple-and single-channel sections, but certain areas of the multiple-channel sections had more diverse habitats. Each fish species was widely distributed by non-metric multidimensional scaling in the multiple-channel sections as compared to those in the single-channel sections. In addition, according to the principal component analysis, each fish species has a preferred environment, and all of them have a wide choice of habitat environments in the multiple-channel sections. Finally, the existence of multiple-channel sections could significantly affect the existence of the fish species under consideration in this study. However, no environmental factors were found to have an influence on fish species in the single-channel sections, with the exception of Rhinogobius nantaiensis. The results show that providing multiple-channel sections in dredging activities could improve fish habitat environments.

“…Environmental agencies accompany mesohabitat surveys with biological surveys for fish and/or macroinvertebrates typically, and both surveys are used to compare with reference stream conditions to generally assess a stream reach's biological integrity [65,66]. Studies assessing the ecological health of streams have extensively relied on linkages between physical habitat quality and biota composition [22,[66][67][68][69][70]. Kaufmann et al (1999) [64] described a field protocol of longitudinally mapping mesohabitat units in sequence, and collecting basic dimensions of each unit and information on riparian vegetation and microhabitat features, i.e., large woody debris (LWD), overhanging bank vegetation, and large rocks.…”

“…Though the physical sciences are employed to a greater extent than the ecological sciences, the most commonly stated objective for projects is to restore the biological integrity by enhancing habitat and water quality [4,5]. However, recovery of biological integrity from restorations has been mixed depending on how initial project goals were defined, and the organism group (i.e., fish, macroinvertebrates, mussels, periphyton) used to assess outcomes [1,[17][18][19][20][21][22][23][24]. Considering the current practices and reported project biological responses, improvements are needed on how to incorporate ecological criteria into the restoration design process, and better understand the potential capacity for ecological recovery within stressed ecosystems.…”

Use of Ecohydraulic-Based Mesohabitat Classification and Fish Species Traits for Stream Restoration Design

Stream restoration practice typically relies on a geomorphological design approach in which the integration of ecological criteria is limited and generally qualitative, although the most commonly stated project objective is to restore biological integrity by enhancing habitat and water quality. Restoration has achieved mixed results in terms of ecological successes and it is evident that improved methodologies for assessment and design are needed. A design approach is suggested for mesohabitat restoration based on a review and integration of fundamental processes associated with: (1) lotic ecological concepts; (2) applied geomorphic processes for mesohabitat self-maintenance; (3) multidimensional hydraulics and habitat suitability modeling; (4) species functional traits correlated with fish mesohabitat use; and (5) multi-stage ecohydraulics-based mesohabitat classification. Classification of mesohabitat units demonstrated in this article were based on fish preferences specifically linked to functional trait strategies (i.e., feeding resting, evasion, spawning, and flow refugia), recognizing that habitat preferences shift by season and flow stage. A multi-stage classification scheme developed under this premise provides the basic "building blocks" for ecological design criteria for stream restoration. The scheme was developed for Midwest US prairie streams, but the conceptual framework for mesohabitat classification and functional traits analysis can be applied to other ecoregions.
