Controlled farming – contribution of genetics to the purpose of breeding of salmonid fish
Mendel, Jan
2016 - Czech
There was made a short survey of practical utilization of genetics in the following spheres: identification of lineages, species and hybrids, utilization of genomic information in breeding programs and selection procedures, sex determination, searching for important QTLs. Byl učiněn stručný přehled praktického využití genetiky v oblastech: identifikace linií, druhů a hybridů, využití genomické informace v chovných programech a selekčních procedurách, sex determinace, vyhledávání významných QTL.

This study, which has been running since 2008, examines the use of the Hamry Water Reservoir as a model for fish community biomanipulation studies with the aim of improving water quality. Of primary interest to the Reservoir administrators, the Elbe River Basin authority s.p., is the maintenance of high water quality for drinking purposes, thereby preventing conflict of interest with multiple stakeholders. In addition, the study aims to determine whether biomanipulation of fish communities can be undertaken effectively in a reservoir. Cílem celé studie, která probíhá již od roku 2008, je využití VN Hamry jako modelového objektu pro biomanipulační zásahy v rámci zlepšení kvality vody v nádrži. Prvotním zájmem správce VN, podniku Povodí Labe, s.p., je vysoká kvalita vody pro pitné účely, takže zde nedochází ke konfliktu zájmů více zainteresovaných stran. Cílem bylo rovněž zjistit, zda je vůbec reálné v podmínkách VN provádět efektivní biomanipulace s rybím společenstvem.

2015 - Czech
Revitalization measures for improving water quality applied at the Plumlov reservoir included total dewatering and dredging of sediment. In 2015, we surveyed the newly established fish community in order to acquire information for future fisheries management. Vodní nádrž Plumlov byla předmětem revitalizačních opatření na zlepšení kvality vody včetně totálního vypuštění a odbagrování sedimentu. V roce 2015 proběhl průzkum nově se vytvářejícího rybího společenstva s cílem získat informace potřebné pro následný management.

Hodnocení rybářského využití koupacích vod v povodí řeky Moravy s ohledem na možné interakce s vývojem kvality vody
Adámek, Zdeněk; Jurajda, Pavel
2015 - Czech
The evaluation of possible relationship between fisheries management and water quality in bathing sites in the Morava River catchment area, as presented on public web pages www.koupacivody. cz, was performed on an example of 24 evaluated waterbodies. On the sites, which belong to the angling grounds, an obvious relationship between the proportion of predatory fish biomass in fish yields (F/C index) and bathing quality of appropriate sites was recorded. Mean F/C values in fish catches, as the most appropriate criterion, amounted to 17.8 and 21.5 in bathing suitable water and bathing suitable water with deteriorated sensory properties, \nrespectively. It seems apparent that the bathing water quality reflects in certain extent the principal characteristics of fisheries management. In carp farming ponds, incorporated legally among bathing sites, this tendency was not so obvious and it seems that not even the intensity of supplementary feeding was the main reason limiting the suitability for bathing. S použitím dostupných údajů o rybářském managementu na celkem 24 koupacích vodách v povodí řeky Moravy bylo provedeno vyhodnocení jeho možného vztahu ke kvalitě vody pro koupání, prezentované na webových stránkách krajských hygienických stanic. Na lokalitách, které jsou rybářskými revíry, je patrný vztah mezi podílem dravých ryb vyjádřeným v biomase vysazovaných i ulovených ryb (F/C index) a zařazením příslušné lokality do jedné z pěti kategorií vhodnosti vody ke koupání (od vody vhodné ke koupání až po vodu ke koupání nebezpečnou). Průměrné hodnoty F/C indexu v úlovcích, jakožto nejvhodnějším kritériu, činily 17,8 pro vody vhodné ke koupání a 21,5 pro vody vhodné ke koupání se zhoršenými smyslově postižitelnými vlastnostmi. Je tedy zřejmé, že kvalita vody s ohledem na její vhodnost ke koupání reflektuje v jistém rozsahu základní charakteristiku rybářského managementu, vyjádřenou zastoupením dravých ryb. V produkčních rybnících, zařazených mezi koupací vody není tento trend tak zjevný.

2015 - Czech
The aim of this report is to evaluate species composition and abundance of juvenile fish communities along specified profiles along the Oder in relation to the assessment of good water status, as a basis for updating the "Plan for the Upper Odra River sub-basin" in accordance with appropriate methodologies laid down by the Ministry of the Environment. Cílem této zprávy je vyhodnocení druhového složení a početnosti společenstev juvenilních ryb na zadaných profilech v povodí Odry ve vazbě na hodnocení dobrého stavu vod, jako podklad pro aktualizaci Plánu dílčího povodí Horní Odry dle platných metodik Ministerstva životního prostředí ČR.
