FishMOT: A Simple and Effective Method for Fish Tracking Based on IoU Matching [PDF]
arXiv, 2023 Fish tracking plays a vital role in understanding fish behavior and ecology. However, existing tracking methods face challenges in accuracy and robustness dues to morphological change of fish, occlusion and complex environment. This paper proposes FishMOT(Multiple Object Tracking for Fish), a novel fish tracking approach combining object detection and ...

The first draft genome assembly and data analysis of the Malaysian mahseer (Tor tambroides)
Aquaculture and Fisheries, 2023 The Malaysian mahseer (Tor tambroides), one of the most valuable freshwater fish in the world, is mainly targeted for human consumption. The mitogenomic data of this species is available to date, but the genomic information is still lacking.

Hydrodynamics of undulatory fish schooling in lateral configurations [PDF]
arXiv, 2010 The thrust benefits of lateral configurations of two-dimensional undulating fish-like bodies are investigated using high-fidelity numerical simulation. The solution of the Navier--Stokes equations is carried out with a viscous vortex particle method.

Molecular Ecology, EarlyView.Abstract Population genomics analysis holds great potential for informing conservation of endangered populations. We focused on a controversial case of European whitefish (Coregonus spp.) populations. The endangered North Sea houting is the only coregonid fish that tolerates oceanic salinities and was previously considered a species (C.

Scientific Reports, 2020 The immune system of sturgeons, one of the most ancient and economically valuable fish worldwide, is poorly understood. The lack of molecular tools and data about infection biomarkers hinders the possibility to monitor sturgeon health during farming and ...

Electrocommunication for weakly electric fish [PDF]
, 2019 This paper addresses the problem of the electro-communication for weakly electric fish. In particular we aim at sheding light on how the fish circumvent the jamming issue for both electro-communication and active electro-sensing. A real-time tracking algorithm is presented.

Genomic Landscape of Divergence in Ballan Wrasse (Labrus bergylta)
Molecular Ecology, EarlyView.ABSTRACT The architecture underpinning genomic divergence is still a largely uncharted territory and likely case‐dependent. Here, we investigated genome‐wide variation in Ballan wrasse, a northeastern Atlantic fish species that displays two sympatric colour morphs, spotty and plain, that have been suggested to represent subspecies.

Chromosome evolution in fishes: a new challenging proposal from Neotropical species
Neotropical IchthyologyWe present a database containing cytogenetic data of Neotropical actinopterygian fishes from Venezuela obtained in a single laboratory for the first time. The results of this study include 103 species belonging to 74 genera assigned to 45 families and 17

Quantifying Bone Collagen Fingerprint Variation Between Species
Molecular Ecology Resources, Volume 25, Issue 4, May 2025.ABSTRACT Collagen is the most ubiquitous protein in the animal kingdom and one of the most abundant proteins on Earth. Despite having a relatively repetitive amino acid sequence motif that enables its triple helical structure, in type 1 collagen, that dominates skin and bone, there is enough variation for its increasing use for the biomolecular species
