  • Amplification of brook trout growth hormone cDNA using polymerase chain reactiono (PCR) produced a nucleotide of 1,120 bp which contained the 5'non-coding region (13bp), an open reading frame (ORF) coding a growth hormone polypeptide consisting of 210 amino acids (630 bp), and a 3'non-coding region (477 bp). In open reading frame s signal peptide of 22 amino acid and 2 potential disulfide bond sites deduced by 4 cysteine residues were obser-bed. Brook trout growth hormone has 97.1%, 94.8%, 94.3%, 91.9%, 66.2%, 63.5%, 62.9%, 62.3%, 53.8% and 48.1% amino acid identity with that of Atlantic salmon, chum salmon, rainbow trout, coho salmon, tuna, tilapia, yellow tail, carp, flounder and eel, respectively.

  • Water temperature affects physical and biological processes in ecologies on river system and is important conditions for growth rate and spawning of fish species. The objective of this study is to compare models for water temperature during the summer season for the Fourchue River (St-Alexandre-de-Kamouraska, Quebec, Canada). For this, three different models, which are CEQUEAU, Auto-regressive Moving Average with eXogenous input and Nonlinear Autoregressive with eXogenous input, were applied and compared. Also, future water temperature in the Fourchue river were simulated and analyzed its result based on the CMIP5 climate models, RCP 2.6, 4.5, 8.5 climate change scenarios. As the result of the study, the water temperature in the Fourchue river are actually changed and median water temperature will increase $0.2{\sim}0.7^{\circ}C$ in June and could decrease by $0.2{\sim}1.1^{\circ}C$ in September. Also, the UILT ($24.9^{\circ}C$) for brook trout are also likely to occurred for several days.
