Geolocation reveals wintering sites of near‐extinct Caucasian breeding sea duck

Ibis, EarlyView.
We obtained 14 sets of full annual cycle geolocator tracks from 13 individual nesting female Velvet Scoter Melanitta fusca from the relict Caucasian population at their last remaining breeding site, Lake Tabatskuri, Georgia. Results showed that females wintered at widespread discrete localities in Ukraine, around the coasts of the Crimean Peninsula and

Excretion Routes of Okadaic Acid and Dinophysistoxin-2 from Mussels (Mytilus galloprovincialis) and Cockles (Cerastoderma edule)

Toxins
The knowledge of the routes of excretion of the toxins accumulated by molluscs is a key step in designing methods that accelerate depuration. In this work, the excretion route, in mussels and cockles, of the main diarrhetic shellfish poisoning (DSP ...

Altered photoperiod affects behaviour in a key fish grazer, the thinlip grey mullet, Chelon ramada

Journal of Fish Biology, EarlyView.
Abstract The aim of this study is to address experimentally the immediate impacts of an alteration of the photoperiod, simulating an extreme artificial light pollution, on the behaviour and stress of a key grazer fish common in temperate coastal ecosystems in Europe, the thinlip grey mullet, Chelon ramada.

An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

Journal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

THE USE OF ALGAE CONCENTRATES, DRIED ALGAE AND ALGAL SUBSTITUTES TO FEED BIVALVES

Makara Seri Sains, 2011
Microalgae have high nutritional value and are used to feed adult and larval stages of bivalves, the larvae of some fish and crustaceans and zooplankton. However, microalgae production for aquaculture animal is very expensive.

The jaws in the jaws: Morphofunctional analysis of the pharyngeal plates of Labrus viridis Linnaeus, 1758 (Teleostei, Labridae)

Journal of Fish Biology, EarlyView.
Abstract Functional morphology highlights the adaptive flexibility of fish feeding strategies across environmental gradients and seasonal variations, providing key insights for the management and conservation of ichthyofaunal communities and their habitats.

Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary

Journal of Fish Biology, EarlyView.
Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

Renal Trichodinosis in the Japanese Rice Fish, Oryzias latipes: First Report and Phylogenetic Classification

Journal of Fish Diseases, EarlyView.
ABSTRACT Investigation of a disease outbreak in a hobbyist's medaka (Oryzias latipes) collection led to the detection of Trichodina sp. in the kidney tubuli of individual fish. Based on this observation, a thorough clinical workup, including native microscopy, histopathology and molecular genetics, was conducted.

Outbreaks of Granulomatous Disease Associated With Vibrio harveyi Infection in Grouper (Epinephelus fuscoguttatus × E. lanceolatus) Aquaculture in Taiwan

Journal of Fish Diseases, EarlyView.
ABSTRACT Between 2015 and 2024, outbreaks of muscular and visceral granulomatous disease, resulting in moderate‐to‐severe mortality in farmed groupers, occurred in southern Taiwan. Initially, affected groupers were screened for granuloma‐associated pathogens, including Mycobacterium spp., Nocardia spp., Photobacterium damselae and Edwardsiella spp ...

Nodular Lesions in the Pyloric Caeca of Sardinella aurita (Teleostei) Associated With the Cestode Anthobothrium sp. 1 Larvae (Platyhelminthes: Eucestoda) Off Tunisia, Mediterranean Sea

Journal of Fish Diseases, EarlyView.
ABSTRACT Examination of round sardinella Sardinella aurita Valenciennes, 1847 (Clupeidae) from the Gulf of Tunis (Tunisia) revealed the first local and Mediterranean record of Anthobothrium sp. 1 sensu Jensen & Bullard, 2010 (Tetraphyllidea incertae sedis, Anthobothrium).
