Trophic niche overlap between flatfishes in a nursery area on the Portuguese coast

open access: yesScientia Marina, 2002
The diets and the trophic niche overlap between seven flatfish species were studied in a coastal nursery adjoining to the Tagus estuary (Portugal). Fish were sampled monthly, from March to November 1999, using a beach seine.

A comparative SEM study of ossicles in the Pleuronectiformes (Teleostei) of the Baltic Sea; pp. 495–517 [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2015
The morphologies of ossicles of the European plaice Pleuronectes platessa Linnaeus, the European flounder Platichthys flesus trachurus (Linnaeus) (Pleuronectidae), and the turbot Scophthalmus maximus (Linnaeus) (Scophthalmidae) are described and compared.

Extinction of Flatfish [PDF]

open access: yesNature, 1883
I HAVE been advised by Mr. Murray of the Challenger expedition to inquire, through your columns, whether the experience of any of your correspondents coincides with mine as to the gradual failure—in some places almost the extinction—of flatfish where whelk-gathering is prosecuted.

Diet, growth and reproduction of four flatfishes on the Portuguese coast

open access: yesScientia Marina, 2010
Four flatfish species were collected between January 2003 and June 2005 from commercial fishing vessels operating with gill nets and bottom trawls along the Portuguese coast in order to examine feeding habits, age and growth and reproduction.

Assessing the Progress of Stock Rebuilding in the Northeast Atlantic Against Levels That Can Produce Maximum Sustainable Yield

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Rebuilding fish stocks to levels above which they produce Maximum Sustainable Yield (MSY) is a management aim for all European commercially exploited stocks. Progress is typically monitored against the fishing mortality that produces MSY in the long term (FMSY), however, the corresponding biomass target (BMSY) is rarely evaluated nor reported.

Benthic visual adaptation by fine-tuning light sensitivity in Japanese flounder (Paralichthys olivaceus)

open access: yesFrontiers in Marine Science, 2022
The habitat occupied by flatfish fry differs considerably in light regime from that of the adult. The diversity of opsins and their expression patterns appear greatest for flatfishes to experience variable light environments.

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 ...

A genetic linkage map of sole (Solea solea): a tool for evolutionary and comparative analyses of exploited (flat)fishes. [PDF]

open access: yesPLoS ONE, 2014
Linkage maps based on markers derived from genes are essential evolutionary tools for commercial marine fish to help identify genomic regions associated with complex traits and subject to selective forces at play during exploitation or selective breeding.

Eye location, cranial asymmetry, and swimming behavior of different variants of Solea senegalensis

open access: yesAquaculture and Fisheries, 2020
Many flatfish species, such as Scophthalmus maximus, Paralichthys olivaceus, Solea senegalensis, are extensively cultured worldwide. In flatfishes, eye migration varies among different species and even within the same species.
