Combined effects of toxic cyanobacteria Microcystis aeruginosa and hypoxia on the physiological responses of triangle sail mussel Hyriopsis cumingii.

The single and combined effects of toxic cyanobacteria Microcystis aeruginosa and hypoxia on the energy budget of triangle sail mussel Hyriopsis cumingii were determined in terms of scope for growth (SfG). Mussels were exposed to different combinations of toxic M. aeruginosa (0%, 50%, and 100% of total dietary dry weight) and dissolved oxygen concentrations (1, 3, and 6.

A Novel Matrix Protein Hic31 from the Prismatic Layer of Hyriopsis Cumingii Displays a Collagen-Like Structure.

In this study, we clone and characterize a novel matrix protein, hic31, from the mantle of Hyriopsis cumingii. The amino acid composition of hic31 consists of a high proportion of Glycine residues (26.67%).

Effect of pH and temperature on antioxidant responses of the thick shell mussel Mytilus coruscus.

This study evaluated the combined effects of seawater pH decrease and temperature increase on the activity of antioxidant enzymes in the thick shell mussel Mytilus coruscus, an ecological and economic bivalve species widely distributed along the East China Sea. Mussels were exposed to three pH levels (8.1, 7.

Anti-predatory responses of the thick shell mussel Mytilus coruscus exposed to seawater acidification and hypoxia.

Ocean acidification and hypoxia, both caused by anthropogenic activities, have showed deleterious impacts on marine animals. However, their combined effect on the mussel's defence to its predator has been poorly understood, which hinders us to understand the prey-predator interaction in marine environment. The thick shell mussel Mytilus coruscus and its predator, the Asian paddle crab Charybdis japonica were exposed to three pH levels (7.

Physiological energetics of the thick shell mussel Mytilus coruscus exposed to seawater acidification and thermal stress.

Anthropogenic CO₂ emissions have caused seawater temperature elevation and ocean acidification. In view of both phenomena are occurring simultaneously, their combined effects on marine species must be experimentally evaluated. The purpose of this study was to estimate the combined effects of seawater acidification and temperature increase on the energy budget of the thick shell mussel Mytilus coruscus.

The complete mitochondrial genome of the midas cichlid (Amphilophus citrinellus).

The midas cichlid (Amphilophus citrinellus) is an important aquarium fish that has served as a model organism for studying sympatric speciation. In this study, we sequenced the complete mitochondrial genome of the midas cichlid. We report that the cichlid's mitochondrial genome is a circular DNA double strand of 16,521 bp length, which contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and 1 control region.

Complete mitochondrial DNA sequencing of Vieja synspila, a cichlid fish.

The Redhead cichlid (Vieja synspila) is an important aquarium fish and a useful phylogenetic organism of the Cichlidae family. In this study, we sequenced the mitochondrial genome of the Redhead cichlid for the first time. The mitogenome (16,543 bp) had the typical mitochondrial characteristics of other cichlid fish, including 13 protein-coding, 22 tRNA, two rRNA genes and one putative control region.

R. F. Elliott 1968 infection in Prussian carp (Bloch, 1782) eggs and its control with herb extracts.

In order to control saprolegniosis in Prussian carp ( (Bloch, 1782) eggs, it is important to screen herb extracts as potential anti- drugs in Prussian carp hatcheries. For this purpose, an oomycete water mould (strain SC) isolated from Prussian carp [ (Bloch, 1782)] eggs suffering from saprolegniosis was characterised morphologically as well as from ITS rDNA sequence data. Initially identified as a sp.

Orthogonal test design for optimization of lipid accumulation and lipid property in Nannochloropsis oculata for biodiesel production.

In order to improve the property of Nannochloropsis oculata as biodiesel feedstock, a L9(3(4)) orthogonal test on limited nitrogen supplementation (0, 0.22 and 0.44 mmol N L(-1)), high iron concentration (1.
