Algae bloom intensity classification using machine learning methods and UAV hyperspectral data

Компьютерная оптика
This paper presents an approach for high spatial resolution hyperspectral image analysis in an applied task of river water condition assessment. The method allows the detection of algal blooms or water pollution by foreign substances.

A network analysis of failure pathways for fish and fish habitat offsets

Conservation Science and Practice, EarlyView.
Biodiversity offsets are widely used to compensate for environmental impacts, yet failures often arise from interacting factors rather than isolated issues. By analyzing co‐occurrence patterns across 48 fish and fish habitat case studies, we identify five recurring failure syndromes: foundational, implementation uncertainty, biological, hydrological ...

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

UAVs in Support of Algal Bloom Research: A Review of Current Applications and Future Opportunities

Drones, 2018
Algal blooms have become major public health and ecosystem vitality concerns globally. The prevalence of blooms has increased due to warming water and additional nutrient inputs into aquatic systems.

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, EarlyView.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Microbiome and Pathobiome Characterization in Farmed Barramundi (Lates calcarifer) During and Post Scale Drop Disease Outbreaks

Journal of Fish Diseases, EarlyView.
ABSTRACT Large‐scale double‐digest RAD sequencing (ddRADseq) datasets generated for genotyping are increasingly available in aquaculture, yet their unmapped reads remain largely unexplored for pathogen surveillance. Here, we evaluated the utility and limitations of repurposing unmapped ddRADseq reads to examine pathogen‐associated and disease ...

Innovative Field Applications of Probiotics, Prebiotics, and Medicinal Plant Products for Disease Control in Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Disease outbreaks and the associated reliance on antibiotics pose major constraints to the sustainability of modern aquaculture. As regulatory pressures increase and consumer demand shifts toward residue‐free production, diverse biological interventions are gaining prominence as viable alternatives to chemotherapeutics.
