growth and whole body composition of lake trout salvelinus namaycush brook trout salvelinus Fontinalis and their hybrid f1 splake salvelinus namaycush salvelinus Fontinalis from first feeding to 16 weeks post first feeding
Aquaculture, 2005Co-Authors: Stephen J Gunther, Richard D Moccia, Dominique P BureauAbstract:Lake trout (Salvelinus namaycush), brook trout (Salvelinus Fontinalis) and their hybrid, F1 splake (S. namaycushS. Fontinalis) account for approximately 80% of total fish stocked for lake rehabilitation in Ontario. Yet, little information exists in the literature on the patterns of growth and whole body composition for these species under hatchery conditions. Such information may be useful for the development of feed requirement and waste output models for these fish species. Growth and whole body composition of lake trout, brook trout and F1 splake (initial body weight ca. 0.2 g) were monitored from first- feeding to 16 weeks post first-feeding. Fish were reared separately, in fry troughs, at ambient water temperature (8 8C) and fed salmonid starter feeds (ca. 53% crude protein, 17% lipid) in excess. Live body weight was determined every 28 days and whole body samples taken every 28 days for analysis of proximate composition. Final body weights were 2.5F0.01, 3.3F0.02, and 4.1F0.03 g for lake trout, brook trout and F1 splake, respectively. Final whole body moisture, crude protein, lipid, ash and phosphorus contents were 80F0.7, 14F0.3, 4F0.7, 2F0.06 and 0.2F0.01 percent for lake trout, brook trout and F1 splake, respectively. Changes in whole body contents (absolute basis, g g fish � 1 ) with increasing body weight were best described by a series of linear (R 2 z0.98) equations. This data can now be used to modify existing feed requirement and waste outputs models; improving their applicability to stocks of lake trout, brook trout and F1 splake. D 2005 Elsevier B.V.

the use of the aquatic moss Fontinalis antipyretica l ex hedw as a bioindicator for heavy metals
Science of The Total Environment, 1996Co-Authors: A Siebert, Jurgen Miersch, I Bruns, G J Krauss, Bernd MarkertAbstract:Abstract Increasing attention given to heavy metals as components of the pollutant load in aquatic ecosystems makes it necessary to find reliable biological indicators. Fundamental investigations into the effect of heavy metals on organisms are therefore required. The aquatic moss Fontinalis antipyretica was chosen as an indicator organism to optimize the indication of heavy metal loads at the physiological and biochemical levels. Investigations into the distribution of the heavy metals Cd, Cu, Pb and Zn showed higher concentrations and less biological dispersion in older parts of the plants than in young shoot tips. In-spite of the considerable fluctuations it was possible to establish a correlation between concentrations of the element zinc in the medium and in the organism when water samples were examined parallel to plant samples. The correlation between various elements found in aquatic moss, above all copper and lead, made it possible to draw conclusions about the accumulation properties of Fontinalis antipyretica with respect to various elements.
