“…For example, while the blooms of the photosynthetic dinoflagellate, Karenia brevis , are naturally occurring, in recent decades, blooms are occurring more frequently, are more widespread, often with higher potency in southwest Florida (Kusek et al 1999 ; Brand and Compton 2007 ), which have been linked to anthropogenic nutrient inputs (Medina et al 2022 ), and are responsible for the widespread mortality of fish and marine mammals (Landsberg 2002 ; Flewelling et al 2005 ). Specifically, these blooms have been shown to repeatedly kill Atlantic tarpon and seriously affect the fishery (Griffin et al 2022 ). In the St. Lucie Estuary and Indian River Lagoon on Florida’s east coast, algal blooms continue to harm the estuaries and their fish communities due to a combination of increased hurricane and precipitation intensity coupled with mismanagement of freshwater flows (Phlips et al 2020 ).…”

Tropical and subtropical coastal flats are shallow regions of the marine environment at the intersection of land and sea. These regions provide myriad ecological goods and services, including recreational fisheries focused on flats-inhabiting fishes such as bonefish, tarpon, and permit. The cascading effects of climate change have the potential to negatively impact coastal flats around the globe and to reduce their ecological and economic value. In this paper, we consider how the combined effects of climate change, including extremes in temperature and precipitation regimes, sea level rise, and changes in nutrient dynamics, are causing rapid and potentially permanent changes to the structure and function of tropical and subtropical flats ecosystems. We then apply the available science on recreationally targeted fishes to reveal how these changes can cascade through layers of biological organization—from individuals, to populations, to communities—and ultimately impact the coastal systems that depend on them. We identify critical gaps in knowledge related to the extent and severity of these effects, and how such gaps influence the effectiveness of conservation, management, policy, and grassroots stewardship efforts.

“…Harmful algal blooms (HABs) are the rapid proliferation of certain microalgal species that can be related to elevated nutrients, temperature spikes, and other environmental triggers (Brusle, 1995;Harvell et al, 1999;Van Dolah, 2000). Toxins produced by certain microalgal species during these blooms can lead to ecological consequences, such as fish kills (Kim and Oda, 2010;Dorantes-Aranda et al, 2015;Murray et al, 2015;Hallegraeff et al, 2023), marine mammal mortality (Van Dolah et al, 2002;Broadwater et al, 2018;Elorriaga-Verplancken et al, 2022), and disruptions to the normal functioning of aquatic ecosystems (Glibert, 2017;Griffin et al, 2023;Oh et al, 2023).…”

IntroductionHarmful algal bloom (HAB)-forming species and populations exhibit substantial intraspecific functional trait variation, which can confer eco-evolutionary advantages. Phenotypic variability among populations can buffer the immediate detrimental effects of environmental fluctuations, with more diverse populations expected to survive changing conditions more efficiently than their uniform counterparts.MethodsIn February 2014, a mixed fish-killing dinoflagellate bloom occurred in the temperate waters of Coffin Bay, South Australia, causing the death of oysters and fish in the area. The bloom was dominated by Karenia mikimotoi and a cryptic species of Heterocapsa. Twenty-one monoclonal Heterocapsa isolates were established from the site and identified as H. ovata using microscopy and universal ribosomal markers (ITS/5.8S and LSU D1/D3 rDNA regions; SSU and cob were used for amplicon sequencing). These isolates were tested for ichthyotoxicity using a bioassay based on cells from the gills of rainbow trout (Oncorhynchus mykiss). Culture fraction preparations (whole cells, supernatant, and lysed cells) were analyzed to determine ichthyotoxicity levels.ResultsThe highest ichthyotoxicity was observed in lysed cells, with surprisingly high inter-strain variability. This suggests that different strains of H. ovata have varying levels of toxicity.DiscussionResults from this study expand our understanding of the adaptive strategies of HAB species and enable predictions of future population dynamics under changing climatic conditions. The substantial phenotypic variability among H. ovatastrains highlights the potential for diverse responses to environmental stressors, underscoring the importance of considering intraspecific variation in ecological and evolutionary studies of HABs.

“…The dinoflagellates have the greatest number of harmful species, some of which produce potent toxins. The dinoflagellate toxins directly affect the ecosystem and are suspected to cause mass fish kills [14,15]. Moreover, it has been reported that toxins from dinoflagellates bio magnify up the food chain and cause mass mortality of finfish [16].…”

Extensive growth of microscopic algae and cyanobacteria results in harmful algal blooms (HABs) in marine, brackish, and freshwater environments. HABs can harm humans and animals through their toxicity or by producing ecological conditions such as oxygen depletion, which can kill fish and other economically or ecologically important organisms. This review summarizes the reports on various HABs that are able to bring about marine fish kills. The predominant HABs, their toxins, and their effects on fishes spread across various parts of the globe are discussed. The mechanism of HAB-driven fish kills is discussed based on the available reports, and existing mitigation methods are presented. Lapses in the large-scale implementation of mitigation methods demonstrated under laboratory conditions are projected. Clay-related technologies and nano-sorption-based nanotechnologies, although proven to make significant contributions, have not been put to use in real-world conditions. The gaps in the technology transfer of the accomplished mitigation prototypes are highlighted. Further uses of remote sensing and machine learning state-of-the-art techniques for the detection and identification of HABs are recommended.
