The Distribution of Pseudodiaptomus marinus in European and Neighbouring Waters - A Rolling Review

Marco Uttieri et. al.

June 2023

Abstract: Among non-native copepods, the calanoid Pseudodiaptomus marinus Sato, 1913 is the species

probably spreading at the fastest pace in European and neighbouring waters since its first record in

the Adriatic Sea in 2007. In this contribution, we provide an update on the distribution of P. marinus

in the Mediterranean and Black Seas, along the Atlantic coasts of Europe, in the English Channel

and in the southern North Sea. Starting from a previous distribution overview, we include here

original and recently (2019–2023) published data to show the novel introduction of this species in

different geographical areas, and its secondary spreading in already colonised regions. The picture

drawn in this work confirms the strong ability of P. marinus to settle in environments characterised by extremely diverse abiotic conditions, and to take advantage of different vectors of introduction. The data presented allow speculations on realistic future introductions of P. marinus and on the potential extension of its distribution range.

Temporal and spatial variation in concentration of early copepod naupliar stages in the Kattegat Sea is partly explained by temperature, salinity, and day of year

Jacob Bonde, nu havbiolog, speciale ved Aarhus Universitet (Anna Neuheimer)

Abstract

Copepod nauplii are a vital food source for many fish larvae and are present across marine and freshwater environments. Copepod nauplii were sampled in the Kattegat Sea from February to May to study the concentration over space and time. It was shown that mean temperature, mean salinity and species-specific effects of day of year (DoY) determined the total copepod nauplii concentration in the Kattegat Sea (explaining 72,16% of the variation). Model predictions show that temperature increases the concentration of copepod nauplii for all species analyzed in this thesis. An increase of mean salinity had a positive or negative effect on the copepod nauplii concentration depending on the species investigated. DoY affected all in different ways over time. These results are discussed with respect to future copepod nauplii concentration and climate change.

Årets pighvarstrygning er sat i gang

This year's turbot striping has started

Mette Schiønning

June 2022

This article covers a succesful story about striping of local turbot with the purpose of restocking the Danish waters. Turbot were caught close to Fåborg and the eggs were transported by Fishlab to Venøsund Fisk og Skaldyr Aps.

In the article picture can Søren Præst be seen striping a turbot.

A new strategy in rearing of European flounder: using live Enchytraeus albidus to enhance juvenile growth

M.E. Holmstrup, S.F. Gadeberg, K. Engell-Sørensen, S. Slotsbo and M. Holmstrup

2022

We have shown that growth of juvenile European flounder can be doubled by feeding live Enchytraeus when compared to traditional methods.

Future production of European flounder will incorporate our new approach to ensure the restocking efforts of the Danish Fisheries Agency (Fiskeristyrelsen).

2018

Article published on Aarhus Universitet, Science and Technology

The project "Production of high quality fish feed from enchytreaid biomass" runs over three years, where we aim will find the optimal conditions for breeding and producing feed based on the worm. This is done in cooperation with Aller Aqua A / S, Fishlab, Venøsund Fisk og Skaldyr ApS, Maximus/Sashimi Royal and Aarhus University.
