Large areas of the Łeba River catchment are inaccessible for fish because of barriers, and this reduces significantly their spawning possibilities. The sea trout Salmo trutta L. population in the Łeba River is sustained through compensatory stocking with smolts. In the autumn of 2007 and 2008, seventy two sea trout were caught in a lake, through which the river flows, several kilometers upstream from its mouth. These individuals were tagged with radio transmitters that were recorded by two automatic stations in the river. They were also monitored with active telemetry. Only 26 of these fish moved upstream (41% in 2007 and 33% in 2008), and five reached the spawning grounds. Neither the release location in the lake nor the size of the fish influenced the timing of the fish entering the river or the extent of their migration. Among the fish originated from smolt stocked in the river segment below the lake, 24% continued to migrate and entered the river after approximately 5.7 days, as compared to 45% of the wild fish entering the river after approximately 2.3 days. Most of the stocked fish remained in the lower reaches of the river, upstream from the lake.

Rzeka Łeba przed ujściem do Bałtyku przepływa przez słonawe eutroficzne jezioro Łebsko. W dorzeczu występuje 21 gatunków ryb i minogów z dominującym pstrągiem potokowym, ciernikiem i cierniczkiem. Od 1960 roku prowadzone są zarybienia trocią wędrowną, której liczebność w wyniku zabudowy hydrotechnicznej rzeki systematycznie malała. Głównymi celami badań była ocena wpływu przegród znajdujących się w dorzeczu na migrację tarłową troci oraz zbadanie ewentualnych różnic w sposobie migracji pomiędzy rybami pochodzącymi z naturalnego tarła i zarybień smoltami.W latach 2007 i 2008 poznakowano znaczkami radiowymi 72 tarlaki troci wędrownej, które wypuszczano do jeziora. Migrację ryb śledzono przy zastosowaniu dwóch stacji automatycznych (ASL) i telemetrii aktywnej. Tylko 26 sztuk troci popłynęło w górę rzeki, z czego 5 osobników dotarło do tarlisk. Stwierdzono, że trocie pochodzące z naturalnego tarła łatwiej odnajdują drogę przez jezioro do rzeki (45% w ciągu 2-3 dni) niż te pochodzące z zarybień smoltami (24% w przeciągu 5-7 dni). Dodatkowo wykazano, że znajdujący się w środkowym biegu rzeki Łeby jaz w Chocielewku, pomimo posiadania przepławki jest poważną przeszkodą w migracjach troci.

The genus Scopulariopsis contains over 30 species of mitosporic moulds, which although usually saprophytic may also act as opportunistic pathogens in humans. They have mainly been associated with onychomycosis, and only sporadically reported as a cause of deep tissue infections or systemic disease. Identification of Scopulariopsis species still largely relies on phenotype-based methods. There is a need for a molecular diagnostic approach, that would allow to reliably discriminate between different Scopulariopsis species. The aim of this study was to apply sequence analysis of partial 28S rRNA gene for species identification of Scopulariopsis clinical isolates. Although the method employed did reveal some genetic polymorphism among Scopulariopsis isolates tested, it was not enough for species delineation. For this to be achieved, other genetic loci, within and beyond the rDNA operon, need to be investigated.

Furunculosis appears from time to time in salmonids in different rivers. It was noted in sea tout from the Dunajec River in 1923 and 1924. In 2007 and 2008, it was noted in sea trout and salmon from Pomeranian rivers, where from 80 to 2,400 sea trout spawners were caught. The degree of infection ranged widely from 0.00% in the Łeba to 74.7% in the Słupia and Rega rivers. In 2007, of the 1,381 sea trout weighing 1949.5 kg caught in the Słupia River, 1031 fish weighing 1,664 kg were cleared for utilization. The most diseased fish were observed in the Słupia and Rega rivers. The number of salmon caught in 2007 and 2008 was lower than that of sea trout and ranged from 2 to 65 individuals from the various rivers. The percentage of infected fish ranged from 8.3% (Słupia) to 58.3% (Rega). Funuculosis was noted more frequently in males than females, as well as in more salmon than in sea trout. Bacteriological assays indicated the presence of Aeromonas hydrophila Complex, Aeromonas sorbia, Pseudomonas flurescens, Streptococus mutans, Streptococus sp. Internal organ bleeding was also noted. In the Vistula, Drwęca, Łeba, and Łupawa rivers and in hatcheries rearing spawners of both salmon and sea trout, no symptoms of furunculosis were noted.
