1. Mechanical properties of the abdominal ventral superficial muscle of the hermit crab, Pagurus pollicarus, were examined under isometric and iso-velocity conditions. The muscle was activated by stimulating its motor nerve at different frequencies. 2. Length-isometric tension relations were measured. Peak tension, Po, was 0'16-0'2MNm" and the sarcomere length of the muscle at the optimum lengt...

1. Effects of temperature on the muscle fibre membrane and synapses of stretcher muscle preparations made from autotomized limbs of the Pacific shore crab (Pachygrapsus crassipes) were investigated. 2. Acclimation of the crabs to different temperatures modified properties of both muscle fibre membrane and synapses. 3. Increased temperature produced an increase in membrane potential of the muscl...

The occurrence of infectious diseases poses a significant threat to the aquaculture industry worldwide. Therefore, characterization potentially harmful pathogens is one most important strategies control disease outbreaks. In present study, we investigated for first time pathogenicity two Vibrio species, metschnikovii, foodborne pathogen that causes fatalities in humans, and areninigrae, bacteri...
