Range expansion and population shifts of estuarine fishes in a changing subtropical estuary

Marine Ecology Progress Series, Journal Year: 2023, Volume and Issue: 728, P. 221 - 238

Catastrophic losses (ca. 95%) of seagrass and increased environmental degradation have occurred during the past decade in Indian River Lagoon (IRL) estuary on US Atlantic coast Florida. Changes were observed abundance 2 closely related sparid fishes these estuarine waters based fishery-independent monitoring efforts over 22 yr: sea bream Archosargus rhomboidalis significantly increased, while sheepshead A. probatocephalus simultaneously declined. These trends a northward expansion into areas where they had never been documented associated with an annual minimum water temperature increase approximately 1.5°C, mean 0.9°C, salinity 7.6 ppt. Lost habitat was often replaced by species belonging to attached macroalgae genus Caulerpa or remained bare. Our findings suggest that bream, tropical herbivore, are expanding poleward northern IRL, which may further negatively impact potential recovery populations via competition. Furthermore, declines seagrasses dependent species, including sheepshead, will likely continue if anthropogenic perturbations persist expand. Long-term is essential for timely detection population changes range shifts better refine direct fisheries management existing determine need recently fish should new emerge.

Stakeholder Engagement as a Core Component of Recreational Marine Fisheries Research, Education, and Conservation

Fisheries, Journal Year: 2024, Volume and Issue: 49(12), P. 565 - 576

Published: Aug. 27, 2024

Abstract Effective modern conservation depends on active stakeholder participation. Although engagement is increasing, the extent of this and successful application outcomes to science management varies regionally among types fisheries. A collaborative model that emphasizes knowledge coproduction with stakeholders better identifies research needs threats, influences policy outcomes. Stakeholder integration can be facilitated by nongovernment organizations, such as boundary organizations. Bonefish Tarpon Trust a science-based, organization founded in 1998 recreational fishers fishing guides focuses marine fisheries Caribbean Sea western North Atlantic Ocean. The engages directly, incorporating their perspectives identify concerns, shape research, contribute data collection, disseminate information, work resource managers scientific researchers address needs. This approach demonstrated case studies show science, assessment findings for flats fishery Ocean, context broader efforts collaboration toward actionable inform management.

Recreational Fisher Local Ecological Knowledge Provides Information Applicable to the Management of an Anthropogenically Impacted Estuary

Fisheries Management and Ecology, Journal Year: 2024, Volume and Issue: unknown

ABSTRACT Anthropogenic impacts to estuaries are increasing globally, and often exceed the capacity of resource managers effectively quantify environmental changes, design implement effective restoration programs, or assess ecosystem response specific projects. We interviewed recreational fishers document spatiotemporal fishing effort over a 40‐year period, analyzed commercial landings, qualitatively compare data seagrass monitoring estimates aerial coverage percent cover four‐decade period for Indian River Lagoon, Florida (USA). Fisher landings mirrored declines in cover, which preceded resulting from large‐scale, harmful algal blooms. A super‐bloom was posited as point ecological collapse Lagoon. recommend engaging stakeholders incorporating local knowledge into management programs monitor improve outcomes by expanding base decisions made.

The green macroalga Caulerpa prolifera replaces seagrass in a nitrogen enriched, phosphorus limited, urbanized estuary

Ecological Indicators, Journal Year: 2023, Volume and Issue: 156, P. 111035 - 111035

Published: Oct. 31, 2023

The Indian River Lagoon (IRL) on Florida's east-central coast is a highly developed eutrophic estuary, experiencing harmful algal blooms (HABs). Beginning in 2011, the IRL experienced multiple phytoplankton HABs that were followed by widespread seagrass losses and expanding of rhizophytic macroalga Caulerpa prolifera. To better understand factors related to changing benthic cover, long-term monitoring data spanning 2011–2020 for C. prolifera percent cover at six locations northern Banana considered multivariate analyses with environmental parameters (temperature, salinity, pH, dissolved oxygen, etc.), nutrient chlorophyll-a concentrations, macroalgal carbon (δ13C) nitrogen (δ15N) stable isotopes, elemental composition (%C, %N, %P), ratios (C:N:P). Data reduction using global Bio-Env + STepwise (BEST) procedure linkage tree (LINKTREE) indicated variable most correlated annual differences was C:P. Following losses, P availability increased, as result heavy rainfall, increased sediment flux, and/or more bioavailable due losses. variables among location C:P, δ13C, which could be less urbanization northernmost sites had lower While not identified significant variable, increase associated four years (2016–2019) high ammonium concentrations (6.26 µM) δ15N values (+8.67 ‰), linking influence human waste. this work suggest reducing stormwater runoff inputs waste will promote recovery seagrasses IRL.

Development of a generalized pseudo-probabilistic approach for characterizing ecological conditions in estuaries using secondary data

Environmental Monitoring and Assessment, Journal Year: 2024, Volume and Issue: 196(8)

Published: July 20, 2024

Under the best circumstances, achieving or sustaining optimum ecological conditions in estuaries is challenging. Persistent information gaps estuarine data make it difficult to differentiate natural variability from potential regime shifts. Long-term monitoring critical for tracking change over time. In United States (US), many resource management programs are working at maximum capacity address existing state and federal water quality mandates (e.g., pollutant load limits, climate impact mitigation, fisheries management) have little room expand routine sampling efforts conduct periodic baseline assessments, especially local scales. Alternative design, monitoring, assessment approaches needed help offset burden of addressing additional needs increase understanding about system resilience when sparse spatially limited. Research presented here offers a pseudo-probabilistic approach that allows use found secondary data, such as on hand other acquired generate statistically robust characterizations estuaries. Our uses generalized framework synthesize different contributors inform probabilistic-like assessments. The methodology relies simple geospatial techniques tools (R package functions) developed US Environmental Protection Agency support like National Coastal Condition Assessment. Using collected Northwest Florida (US) estuaries, demonstrations suggest produces condition results with reasonable statistical confidence, improved spatial representativeness, value-added information.
