Testing length-based reference points in a management strategy evaluation for cuckoo ray (Leucoraja naevus) and thornback ray (Raja clavata)

Autor: Tanja Miethe, Helen Dobby

Publikováno v: ICES Journal of Marine Science. 79:129-146

Elasmobranchs grow relatively slowly and mature at a relatively high age, leading to longer generation time. Due to low fecundity of these stocks, sufficient numbers of mature individuals are important to ensure a viable recruitment level and sustain

Reference points for the length-based indicator Lmax5% for use in the assessment of data-limited stocks

Autor: Tanja Miethe, Yves Reecht, Helen Dobby

Publikováno v: ICES Journal of Marine Science. 76:2125-2139

In the absence of abundance indices from scientific surveys or commercial sources, reliable length frequency data from sampled commercial catches can be used to provide an indirect assessment of fishing mortality. Length-based indicators are simple m

Impact assessment of a fisheries closure with effort and landings spatial analyses: A case study in the Western Baltic Sea

Autor: J. Rasmus Nielsen, Christian von Dorrien, Tanja Miethe, Francois Bastardie

Publikováno v: Fisheries Research. 157:170-179

Commercial fisheries in the Western Baltic Sea (WBS; ICES Subdivisions 22–24) are dominated by Danish and German vessels. By combining and processing logbook and Vessel Monitoring System (VMS) data for Germany and Denmark, we compare patterns of sp

The effects of periodic marine inflow into the Baltic Sea on the migration patterns of Western Baltic spring-spawning herring

Autor: Uwe Böttcher, Tanja Miethe, Christian von Dorrien, Tomas Gröhsler

Publikováno v: ICES Journal of Marine Science. 71:519-527

Western Baltic spring-spawning herring (WBSSH, Clupea harengus L.) perform seasonal migrations between feeding grounds in the Skagerrak and Kattegat and their spawning sites in the Western Baltic Sea. The Sound, connecting the Kattegat to the Western

Environmental challenges improve resource utilization for asexual reproduction and maintenance in hydra

Autor: Tanja Miethe, Boris H. Kramer, Felix Ringelhan, Ralf Schaible

Publikováno v: Experimental Gerontology. 46:794-802

Variation in life history can reflect genetic differences, and may be caused by environmental effects on phenotypes. Understanding how these two sources of life history variation interact to express an optimal allocation of resources in a changing en

Modelling the evolutionary effects of a coastal marine reserve on different ecological guilds of fish

Autor: Calvin Dytham, Jonathan W. Pitchford, Tanja Miethe

Publikováno v: Journal of the Marine Biological Association of the United Kingdom. 91:1369-1380

Marine reserves are used as a management tool to ensure sustainability of fish stocks. Using an individual-based model, we compare the evolutionary effect of a reserve located on a nursery ground, spawning ground, feeding ground, or in a year-round h

An Individual-based Model for Reviewing Marine Reserves in the Light of Fisheries-induced Evolution in Mobility and Size at Maturation

Autor: Tanja Miethe, Calvin Dytham, Jonathan W. Pitchford

Publikováno v: Journal of Northwest Atlantic Fishery Science. 41:151-162

Size-selective fishing mortality may induce evolutionary changes to smaller size at maturation in fish stocks. Marine reserves can be a useful management tool dealing with the ecological and evolutionary effects of fisheries. We examine the effect of
