Abstract:
... In this paper, we provide new data on fish resource exploitation during the Mesolithic and Neolithic period on the Atlantic coast of the Iberian Peninsula. Evidence from four different sites is presented: Vale Marim I (end of the seventh/beginning of the sixth millennium cal BCE) and Vale Pincel I (2nd and 3rd quarters of the sixth millennium cal BCE), both located on the southwestern Portuguese c ...

Abstract:
... This study aimed to add light-avoidance as a categorizing technique for the study of mesopelagic acoustic layers. Data recorded along the 20° W parallel from 20° N to Iceland showed three types of mesopelagic layers: the non-avoiding non-migrant deep scattering layer (NMDSL), which dropped its intensity toward the north, the avoiding migrating fish layers (MDSL), which were more intense at upwelli ...

Abstract:
... Assessment and intelligent monitoring of fish freshness are of the utmost importance in yield and trade of fishery products. Rapid and precise assessment of fish freshness using conventional methods considering the great volume of industrial production is challenging. In this study, instead of feature-engineering-based methods, a novel and accurate fish freshness detection is proposed based on the ...

Excavations of Mesolithic peat bog sites with good preservation of organic materials in the Trans-Urals brought to light direct evidence of fishing including bones of freshwater fish, mainly perch and pike and various fishing tools. Harpoons and an intact fishing hook were found in the Early Mesolithic layer of Beregovaya 2 site. Middle Mesolithic layers yielded a harpoon and/or leister head, a fi ...

The objective of this study was to assess the input of the offshore zone to the total fish production. Hydroacoustics in areas > 5 m deep were sampled during the cold-dry season for 2 consecutive years. Results showed low fish densities (200–300 ind. ha⁻¹), low biomass (< 1 kg ha⁻¹) and fish of small siz ...

The aim of this study was a longitudinal description of the ontogeny of the adult electric organ of Campylomormyrus rhynchophorus which produces as adult an electric organ discharge of very long duration (ca. 25 ms). We could indeed show (for the first time in a mormyrid fish) that the electric organ discharge which is first produced early during ontogeny in 33-mm-long juveniles is much shorter in ...

Abstract:
... The developments in the study of digeneans of deep-sea fish in the 21st Century are documented and discussed. Most recent work has been on the bathyal fauna (i.e. 1,000m-2,999 m depth), with virtually nothing on the abyssal fauna (i.e. deeper than 3,000 m). The one study on hydrothermal vent digeneans has indicated that these regions probably harbour a distinctive fauna. The demarcation of the dee ...

Abstract:
... Mycotoxins are difficult to monitor continuously, and a tool to assess the risk would help to judge if there is a particular risk due to the inclusion of certain feed ingredients. For this, the toxin contents of 97 commercial fish feeds have been estimated, and the most prominent toxins in fish feed are calculated to be deoxynivalenol, zearalenone, fumonisins and enniatins. These pose a risk to fi ...

The periodic color motifs such as the spots or stripes that adorn the coat of vertebrates have served as emblematic systems in empirical and theoretical studies of pattern formation, because they vary extensively between taxa but often have conserved orientation and are highly reproducible within species. Two major patterning theories have been proposed, namely instructional signaling, in which po ...
