title: COVID-19-Todesfälle in Deutschland

description: Im Datensatz 'COVID-19-Todesfälle in Deutschland' werden die Todesfälle in Bezug auf COVID-19 in Deutschland bereitgestellt. Darüber hinaus wird neben der Anzahl der übermittelten Todesfälle der Fall-Verstorbenen-Anteil berechnet.
Angaben zum Tod zählen zu den melde- und übermittlungspflichtigen Inhalten. Bei der Ermittlung von Todesfällen und der Bewertung der entsprechenden Informationen in den Gesundheitsämtern unterschiedlich vorgegangen. In der Folge könnte es einerseits zu einer Unterschätzung der Anzahl der Todesfälle, andererseits zu einer Überschätzung des Anteils der Verstorbenen einer Infektionskrankheit kommen. Ausführlich Hinweise zur Datenerhebung und Interpretation können der Datensatzdokumentation entnommen werden.

title: Havforskningsinstituttet Tråling Postsmolt laks 2025 Altafjord

description: The dataset includes Institute of Marine Research data from trawl stations in Altafjord, Norway in 2025. 

Post-smolts were collected in the outer parts of the fjord systems in late spring and early summer with a specialized surface trawl for live fish sampling, towed behind a suitable fishing vessel (15-25 m). The trawl is 5 m deep and up to 35 m wide depending on speed through water.
The trawl is mounted to a system where smaller catch, such as post-smolts are separated from other catch, and remain free swimming in low turbulence in a hydrodynamic aquarium. The separation takes place when the current flow through a net tunnel and over two 45 degrees racks. The first rack (10 mm between bars) lifts the catch to the next (20 mm between bars) where the separation is done. Everything wider than 20 mm will continue to the cod end of the trawl. Details of the post-smolt trawl are described in Holst and McDonald (2000), Fisheries Research 48, pp 87-91. The standard trawling speed is 2–3 knots (STW), with an average duration of approximately 45 minutes per haul. 

Lice counts on post-smolts were performed on the ship as soon as possible after they were captured. The fish were killed using an overdose of Benzocaine 200 mg/ml. Lice counts were performed with the fish submerged in a white plastic tub (5-10 l) using a strong headlamp (&gt;500 lumen). The counts were only performed by personnel with special training in identification of all salmon lice stages. The following categories were recorded: copepodite, chalimus 1, chalimus 2, pre-adult, adult male and adult female. Fish length in mm and mass in gram were recorded. All post-smolts were then frozen for subsequent analysis.
