“…At a regional, across‐estuary scale, Striped Bass on a foraging migration had a heterogeneous across‐estuary distribution and consumed a diverse diet across New England estuaries that resulted in high but variable prey consumption (Ferry and Mather 2012). At the whole‐estuary scale, a consistently large number of migrating Striped Bass seasonally resided in PIE for a prolonged period in summer (mean: 51–72 days; Pautzke et al 2010; Kennedy et al 2016; Taylor et al 2019). At a within‐estuary scale, Striped Bass that were seasonally resident in PIE exhibited spatially explicit distribution patterns that had distinct behaviors (Pautzke et al 2010; Taylor et al 2019).…”

At a within‐estuary scale, Striped Bass that were seasonally resident in PIE exhibited spatially explicit distribution patterns that had distinct behaviors (Pautzke et al 2010; Taylor et al 2019). Together, these results show that Striped Bass used a range of geographic scales (large coast‐wide, regional across‐estuary, whole‐estuary, within‐estuary).…”

“…We combined telemetry data that quantified fish dynamic distribution with geomorphology to understand the relationship between Striped Bass and physical drivers (Figure 2C). At the whole‐estuary scale, we connected concentrations of Striped Bass feeding within PIE to whole‐estuary physical discontinuities such as sand bars, drop‐offs, and confluences that can act to concentrate forage (Kennedy et al 2016; Taylor et al 2019). This approach required development of metrics for whole‐estuary scale heterogeneity (Kennedy et al 2017).…”

“…The geographic boundary of fish movements corresponded to the 20‐km 2 PIE ecosystem in that some tagged Striped Bass visited all installed receivers (Figure 3A), and individual fish movements connected receiver locations estuary‐wide (Figure 3B). In a clustered spatial framework, more individual Striped Bass used the complex bathymetry of the middle region (Taylor et al 2019; Figure 3A). In our second example, we examined tagged Blue Catfish, Ictalurus furcatus , that were detected weekly for 5 months in a midwestern reservoir ( n = 48 fish; Milford Reservoir, Kansas).…”

“…(E) Alewives could only move past the second barrier during high flows (8 of 21 upstream migrants passed the second barrier in 2007). Methods and related trends are described in Taylor et al (2019), Gerber et al (2019), and Frank et al (2011).…”

By merging our specialization silos, fisheries professionals can expand the options that are available to them to address difficult fisheries and aquatic conservation problems, which require an understanding of spatial patterns in geographically large systems. Our purpose is to start a profession‐wide conversation about additional ways to think about and use spatial data. We use case studies to illustrate how identifying and merging multiple specialized approaches (e.g., fish tracking, fish surveys, geomorphology, social science, jurisdictional viewpoints) can create an ensemble that has advantages over the use of any single approach alone. Thus, our perspective is not about solving a specific technical problem with a new tool, but about the benefits of identifying gaps in data from one specialized approach, and filling those gaps with data from other specialized approaches. If multiple approaches are coordinated through a larger, problem‐specific planning strategy, the result can be better outcomes for difficult problems through creative integration. We encourage others to add constructive ideas to the views initiated here.

Can Identifying Discrete Behavioral Groups With Individual-Based Acoustic Telemetry Advance the Understanding of Fish Distribution Patterns?

Identifying patterns of organismal distribution can provide valuable insights for basic and applied marine and coastal ecology because understanding where animals are located is foundational to both research and science-based conservation. Understanding variation in distributional patterns can lead to a better assessment of ecological drivers and an improved ability to predict consequences of natural and altered relationships. Here, our purpose is to explore if quantifying coexisting groups of individual fish predators advances our understanding of field distribution patterns. Toward this end, we quantified locations of 59 acoustically tagged striped bass (Morone saxatilis) within a 26-stationary unit telemetry receiver array in Plum Island Estuary (PIE), MA, United States. We then used cluster analyses on spatial and temporal-spatial metrics from this dataset to (1) assess if distinct groups of individuals coexisted, (2) quantify group characteristics, and (3) test associations between groups and distribution (e.g., physical site type and region). Based on multiple lines of evidence, we identified four groups of striped bass with different space use patterns that persisted across seasons (summer and fall). Similar-sized striped bass clustered at spatial and temporal scales at which individuals within distinct groups could, and did, physically overlap. In addition, distributional groups were linked to components of physical site type and region suggesting that discrete groups of individuals can interact differently with the environment within the same ecological system. The identification of these distinct groups of individuals creates a baseline from which to explore further ecological implications of grouping behavior for research and conservation in geographically large, temporally dynamic, and spatially heterogeneous marine and coastal environments.
