The effects of dietary protein level on the growth performance and ammonia excretion of the leopard coral grouper,Plectropomus leopardus were investigated for eight weeks. Fish were fed diets with 40, 45, 50, 55 and 60%

The complete mitochondrial genome of Hemigrammus bleberi was obtained by the traditional polymerase chain reaction (PCR)-based sequencing approach. The mitogenome of H. bleberi was determined as 17 021bp in length, including 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. Phylogenetic tree was constructed based on the complete mitogenomes of the species and closely related 21 teleost species to assess their phylogenetic relationship and evolution.

Pond smelt Hypomesus olidus is a small-sized economic species of freshwater fish with delicious meat and high output. In this study, the complete mitochondrial genome of H. olidus sequenced to be 16,786 bp in length, including 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a control region. The overall base composition of H. olidus is 24.3% for A, 27.3% for T, 29.2% for C and 19.2% for G, with a slight A þ T bias. The mitogenome sequence data may provide useful information to the population genetics analysis of H. olidus and the elucidation of evolutionary mechanisms in Hypomesus fish.

The traditional polymerase chain reaction method was employed to obtain the complete mitochondrial genome of Andinoacara rivulatus from Lizigu farm, Tianjin city, China. The mitogenome was determined to be 16,585 bp in length. It contains 13 protein-coding genes, 2 rRNAs and 22 tRNAs. The sequence structure of non-coding control region was also analyzed. This is the first report on the complete mitogenome sequence of A. rivulatus.
