Dynamic colour change predicts movement behaviour in a diadromous fish

Journal of Fish Biology, EarlyView.
Abstract Dynamic changes in colour and pattern facilitate key behavioural functions in animals, particularly camouflage for predator avoidance. However, the benefits of colour change depend on the environmental and behavioural contexts. We tested how colour change interacts with movement behaviour in a freshwater fish by filming individuals in an open ...

Non‐native pink salmon Oncorhynchus gorbuscha carcasses benefit native benthic macroinvertebrates

Journal of Fish Biology, EarlyView.
Abstract The invasion of the North Atlantic by pink salmon Oncorhynchus gorbuscha has raised concerns regarding their impact on coastal rivers. Although the influence of marine‐derived nutrients from returning adult O. gorbuscha on rivers in their native range has received much attention, the ecological consequences of invasive O.

Multilinear Models for the Prediction of Brown Shrimp Harvest in Mississippi Waters

Gulf Research Reports, 1983
A multilinear regression analysis of water temperature, salinity, and number of postlarval brown shrimp in nursery areas was used to predict the June and July commercial harvest of brown shrimp in Mississippi waters. A total of 80.2% of the variation in harvest was accounted for by this model.

Colorimetric indicator films based on carboxymethyl cellulose and anthocyanins as a visual indicator for shrimp freshness tracking

Heliyon
This study aimed to evaluate the response efficiency of colorimetric indicator films based on carboxymethyl cellulose (CMC) incorporated with different anthocyanins [Karanda alone (CMC/AK), butterfly pea alone (CMC/AB), and a mixture of anthocyanins from

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Environmental drivers of shrimp abundance: comparing insights from local ecological knowledge and empirical modeling

Frontiers in Marine Science
Environmental changes in the ocean are increasingly affecting commercially important fishery species. The relationship between environmental parameters and the abundance, distribution, phenology and timing of the reproductive cycles in marine organisms ...

Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Short‐term performance responses of an intertidal fish to sedimentation and warming

Journal of Fish Biology, EarlyView.
Abstract Climate change is altering coastal ecosystems by causing environmental fluctuations, such as increases in temperature and turbidity, which pose major implications for fish physiology and behaviour. Increases in temperature affect fish food intake, swimming capacity and oxygen delivery, while increases in turbidity can impair or enhance prey ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

Journal of Anatomy, EarlyView.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Effect of cadmium and glutathione on malic enzyme activity in brown shrimps (Crangon crangon) from the Gulf of Gdańsk

Oceanologia, 2011
The high level of cadmium in the abdominal muscle of the brown shrimp Crangon crangon is due to the serious pollution of the water in the Gulf of Gdansk. The inhibition of malic enzyme (ME) activity by cadmium, and in consequence the reduced formation of
