UCSB SONGS Mitigation Monitoring: Reef Survey - Fish Fecundity, Feeding, and Somatic Growth
These data describe annual estimates of the fecundity, gut fullness, and somatic growth of five fish species at three subtidal reefs collected as part of the San Onofre Nuclear Generating Station (SONGS) Mitigation Monitoring Program. Data collection began in 2009 at an artificial reef (Wheeler North Reef in Orange County, CA) and two natural reference reefs (San Mateo Kelp in Orange County, CA and Barn Kelp in San Diego County, CA). Fish were collected annually at each reef between May and October.
Data to support manuscript: A Comparison of Two ROV Survey Methods Used to Estimate Fish Assemblages and Densities Around a California Oil Platform
This fish dataset was collected at platform Harmony, between Aug 25 and Aug 26, 2018. The ROV fish survey was done with two methods: industry (mimicking an inspection survey conducted for platform structural inspections) and biological method. Due to differences between the two methods in the positioning of the ROV vis a vis the jacket crossbeams, fish densities and diversities were different between the two methods at the platform bottom. This dataset provides fish counts and the relevant survey parameters (transect length and depth).
Seasonal surveys of fish abundance and diversity in streams of central, eastern, and southern Arizona, USA (2016-2019)
Fish communities in desert streams are shaped by both the long-term selective pressures of streamflow regimes and the short-term effects of floods and droughts. Between spring 2016 and spring 2019 we conducted seasonal sampling of nine streams across the state of Arizona, USA on a gradient of flow regime variability. We calculated populations size for each species at all surveys to analyze seasonal and long-term variations in fish community composition. We additionally used the data to calculate annual rates of fish biomass production. This data set includes the raw catch data from three pass depletion electrofishing, population size estimates at each season, sampling locations, and the USGS stream gauges we used to obtain streamflow data.
Fish surveys of the Upper Yukon and Tanana Rivers 2020–2022
<p>From summer 2020 through fall 2022, Alaska Department of Fish and Game (ADF&G), Division of Sport Fish staff will conduct a rapid, systematic inventory of anadromous and resident fish distribution and associated aquatic and riparian habitat in select drainages of the upper Tanana River and in select drainages of the Fortymile River and adjacent Yukon River drainages. This proposal is part two of a multi-year inventory effort that began in 2019, when project staff inventoried fish assemblages in Yukon & Tanana river drainages downstream of the 2020 study area. In 2020 project staff will continue where they left off and continue working upstream in those drainages. Target streams will be selected to fill gaps in coverage of the State of Alaska's Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fishes (AWC) in freshwater habitats expected to support anadromous fish populations likely to be impacted by human activities. Each of two crews will sample standardized target stream reaches using electro-fishers, with sufficient effort to collect all species (perhaps with the exception of rare species) of the extant fish community. At each sampling site, crews will also document standard aquatic and riparian habitat characteristics. These observations will be recorded in the Alaska Freshwater Fish Inventory database (AFFID) and made publicly available via the AFFID internet mapping service. For each water body in which anadromous fish are observed, nominations to the AWC will be submitted.</p> <p>Crews sampled 135 sites from 2020–2022.</p>
An updated survey of freshwater fishes within Letchworth State Park and surrounding areas of the Genesee River
<p>The goal of this study was to gather information about freshwater fishes in Letchworth State Park (42.615275°N, -77.992825°W), a portion of New York State-owned land located in the Genesee River watershed that lacks known data about its fish diversity. The fish collection took place between 2017 and 2019 in the Genesse River upstream and downstream of the falls using gill, hoop, and seine netting and electrofishing. This was the first attempt at a comprehensive survey of this portion of the river, which allowed for a baseline to be established regarding fish biodiversity in the region. The updated total number of species found in this portion of the Genesee River was 25, 22 of which were newly identified downstream of the falls, in Letchworth State Park. We encourage further collection and continuation of this survey with consistent sampling techniques to promote ongoing field surveys and fish collection that inform freshwater fish diversity in stream ecosystems across the globe.</p>

Data from: Navigating the scales of diversity in subtropical and coastal fish assemblages ascertained by eDNA and visual surveys
<p>Environmental DNA (eDNA) metabarcoding emerges as a powerful method, allowing a more exhaustive investigation of fish fauna than any other methods. Yet, the general use of eDNA as a replacement of traditional methods such as visual surveys or physical sampling remains debatable. Therefore, a prior understanding of eDNA's spatial resolution is necessary. This study aimed to compare the assessments of fish diversity at three spatial scales by eDNA, underwater visual census (UVC), and diver-operated video (DOV) surveys across 21 reef sites in northern Taiwan. The specific objectives were to explore the regional species pool (γ-diversity), reveal spatial patterns of fish assemblages (β-diversity), and disentangle the relationships between fish assemblages and benthic composition (α-diversity). At the γ-diversity level, a total of 438 marine fish species were detected across methods. eDNA exhibits an extraordinary power to explore the regional species pool given sufficient replication, a power which is unachievable by DOV and UVC. At the β-diversity level, all the methods successfully revealed the same spatial patterns of beta diversity and the distance decay of similarity in fish assemblages. At the α-diversity level, none of the methods is capable of investigating the entire resident fish fauna, but visual surveys are more suitable for scrutinizing interactions between fish and benthos. Instead of undiscriminatingly recommending a combination of eDNA with traditional survey methods, we suggest implementing specific surveys in accordance with the ecological questions of interest.</p>

Santa Barbara Channel fish surveys at deep reefs: Footprint, Piggy Bank, Anacapa Passage
The dataset contains fish surveys from deep natural reefs in the northern Santa Barbara Channel Islands, Southern California, mainly at reefs named Piggy Bank, Footprint (local names) and Anacapa Passage. Data collection began in 1995. Reefs are located at depths between 30 and 360 m (100 and 1,180 feet). Sampling was by the manned submersibles Delta and DualDeepworker and an unmanned Remotely Operated Vehicle (ROV). These sites included a wide range of such habitats as banks, ridges, and carbonate reefs, ranging in size from a few kilometers in length to less than a hectare in area. On these features, we focused on hard bottom macrohabitats, including kelp beds, boulder and cobble fields, and bedrock outcrops. Transects were not deliberately revisited; some reefs were surveyed as many as four times per year. All transects are 2 m wide; transect length varied (see data). The dataset includes two tables: (1) the fish counts at Piggy Bank, Footprint, and Anacapa Passage; and (2), the habitat associated with each of the survey segments. Fishes were identified to lowest possible taxon (usually species), and verified against the WoRMs database (http://www.marinespecies.org/).
Santa Barbara Channel fish and invertebrate surveys at oil and gas platforms
Dataset contains occurrences of fish and invertebrates at nine oil and gas platforms between 1995 and 2011 in the southern California (Pt. Arguello to Long Beach). Observations were collected using a manned submersible at depths ranging from 29 – 224 meters (95 - 739 feet). Data are organized into two tables: (1) the fish count (1995-2000) and (2) the invertebrate count (1997-2011). Fish surveys were conducted primarily at nine Platforms (Irene, Hidalgo, Harvest, Hermosa, Holly, Gilda, Grace, Gina, Gail) in the Santa Barbara Channel and Santa Maria Basin. Invertebrate surveys were collected at these nine platforms plus Platform Edith, located off Long Beach (1998) and partial submersible surveys were completed around Platforms C, B, A, Hillhouse, Henry, Houchin, Hogan, and Habitat (2000). See additional methods under “Methods” and citations therein. The Santa Barbara Channel and Santa Maria Basin are situated in a dynamic marine transition zone between the regional flow patterns of central and southern California. The Santa Barbara Channel is about 100 km long by about 50 km wide (60 x 20 miles) and is bordered on the south by the Northern Channel Islands (San Miguel, Santa Rosa, Santa Cruz, and Anacapa). The smaller Santa Maria Basin is located off Pt. Arguello to the northwest. The entire area is bathed in a complex hydrographic system of currents and water masses. The convergence of different water masses in the Santa Barbara Channel results in relatively large scale fluctuations in physical parameters (e.g., temperature, salinity, oxygen, and nutrient concentrations) and biotic assemblages (e. g., flora and fauna).
Santa Barbara Channel fish surveys at shallow outcrops
Nine nearshore, shallow-water rock outcrops, seven along the mainland and two off Anacapa Island, were monitored annually from 1995 to 2000. All locations were surveyed using scuba, and belt transects was were conducted at each site. These natural outcrops are geographically distributed across the Santa Barbara Channel providing opportunities for spatial and temporal comparisons between natural reef and oil/gas platforms. Fish surveys at platforms were conducted using scuba within a few days of these surveys at rock outcrops; the data can be viewed at: https://portal.lternet.edu/nis/mapbrowse?scope=edi&identifier=113 This scuba project was conducted and reported under a cooperative agreement (Agreement 1445-CA09-95-0836) between the U.

Shrub Survey: Effect of Burning Patterns on Vegetation in the Fish Lake Burn Compartments
This study examines the effects of long-term prescribed burning treatments on vegetation structure and composition, productivity, and nutrient cycling in upland oak savanna and woodland vegetation. The basis for the study is an ongoing, experimental prescribed burning program begun in 1964 at Cedar Creek, and a similar program operating since 1962 on the adjacent Helen Allison Savanna property (owned by The Nature Conservancy). These prescribed burning programs are designed to subject upland oak communities (and some old fields) to different burn frequencies and patterns of burning, with the ultimate objectives of 1) restoring and maintaining the historically important savanna and open woodland vegetation, and 2) providing information about the effects of different burning patterns on vegetation structure and composition. This study addresses the latter of these two purposes and expands on it by also investigating possible influences of fire on resource availability (nutrients, water, and light) and net primary productivity. This study represents a continuation and expansion of experiments 015 and 094.

Data from: Pathways of cryptic invasion in a fish parasite traced using coalescent analysis and epidemiological survey
Introduced species have the potential to outperform natives via the introduction of new parasites to which the native ecosystem is vulnerable. Cryptic diversity within an invasive species can obscure invasion patterns and confound proper management measures. The aim of this study is to use coalescent theory based methodology to trace recent routes of invasion in populations of Ligula intestinalis, a globally distributed fish parasite possessing both native and recently introduced populations in North Africa. Molecular analyses of mitochondrial DNA discerned a pronounced genetic divergence between introduced and native populations. Distribution of mitochondrial haplotypes demonstrated common origin of European populations with North African parasites sampled from introduced fish species in Tunisia. To test the suggested pathway of introduction, microsatellite data were examined in a model-based coalescent analysis using the software MIGRATE, where Europe to Tunisia direction of migration was favoured over alternative hypotheses of gene flow. Specificity of Tunisian populations to different host species was assessed in an epidemiologic survey confirming prevailing host-based division between introduced and native parasites in North Africa. This approach combining advanced analysis of molecular markers with host-specificity data allows revealing the evolution of host-parasite interactions following biological invasion and provides basis for devising future management measurements.
