Visual Modelling to Predict Behavioural Responses of Catsharks, Skates, and Plaice to Artificial Light for Use in Bycatch Reduction

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Light can be used to deter bycatch from fishing nets, but few studies have aimed to quantify how species view and respond to light. Here, we used visual models to predict how target (plaice Pleuronectes platessa) and bycatch (small‐spotted catshark Scyliorhinus canicular and undersized skates, Raja spp) species, captured in mixed demersal ...

Some Notes on the Energy Metabolism of Gadus callarias and Gadus virens in Relation to Body Size

open access: yesJournal of Mathematical and Fundamental Sciences, 2019
The present work of oxygen consumption in Gadus callarias and Gadus virens shows that there is a connection between the body size and the acclimation time required for reaching a "normal" level of metabolism after being transferred to another aquarium ...

Walking the cod: an investigation into the relative robustness of cod, Gadus morhua, skeletal elements

open access: yesInternet Archaeology, 1999
A simple experiment is described which details what happens to the bones of cod when they are walked on by a man. The pattern of fragmentation for various elements is illustrated and an index of robustness proposed for those elements in a cod skeleton ...

Condition factor, heavy metals and polychlorinated biphenyls (PCBs) in the muscle of fishes harvested in, and imported into Lagos, Nigeria

open access: yesAceh Journal of Animal Science, 2020
Fish is an important part of the human diet, are at the top of the aquatic food chain with a high propensity to accumulating contaminants like heavy metals and polychlorinated biphenyls (PCBs) which are toxic to humans.

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

Testing Potential Fish Fraud in Community-Supported Fisheries [PDF]

open access: yes, 2016
The seafood industry has long been plagued by the substitution of a species under a false label. Seafood mislabeling is a major concern in the management of fish and marine species.

A study of the enzymatic hydrolysis of fish frames using model systems [PDF]

open access: yes, 2011
A model system was employed to study the operating conditions and primary parameters of enzymic hydrolysis of cod proteins. Pancreatin, papain, and bromelain were used to hydrolyse minced cod fillets under controlled conditions and with the rate of ...

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing

Diversity in Ancestral Caddo Vessel Forms in East Texas Archaeological Sites [PDF]

open access: yes, 2015
Ceramic vessels from ancestral Caddo sites in East Texas are diverse in form, size, manufacture, and decoration, both spatially and temporally. Variation in these attributes, including vessel form, also “is connected with particular local and regional ...
