Anthropogenic causes of jellyfish blooms and their direct consequences for humans: a review
Although recent articles state that jellyfish populations are increasing, most available evidence shows that jellyfish abundances fluctuate with climatic cycles. Reports of increasing prob- lems with
Unusual population explosion of the giant jellyfish Nemopilema nomurai (Scyphozoa: Rhizostomeae) in East Asian waters
The results from both laboratory-rearing experiments and field investiga- tions were combined to construct the seasonal life cycle and geographical distribution of N. nomurai in eastern Asian waters.
Length-weight relationships of important zooplankton from the Inland Sea of Japan
Measurements of dry weight, carbon- and nitrogen contents together with the body length of important zooplankton from the Inland Sea of Japan were made using freshly caught specimens, and species specific regression equations were calculated for 10 species of Copepoda.
Population biomass, feeding, respiration and growth rates, and carbon budget of the scyphomedusa Aurelia aurita in the Inland Sea of Japan
The carbon budget of the A. aurita population typical of early summer in the Ondo Strait was constructed and predicted population-feeding rate was higher than the population-food requirement for both metabolism and growth, indicating that food supply was sufficient to sustain the observed growth rate.
Fecundity studies of neritic calanoid copepods Acartia clausi Giesbrecht and A. Steueri Smirnov: A simple empirical model of daily egg production
Fecundity studies of neritic calanoid copepods, Acartia clausi Giesbrecht and A. steueri Smirnov, were made under controlled laboratory conditions and a simple model equation describing fecundity was derived from the combined effects of temperature and chlorophyll a on daily egg production.
Why does Calanus sinicus prosper in the shelf ecosystem of the Northwest Pacific Ocean
Shelf waters may provide a suitable habitat for C. sinicus because temperature, phytoplankton food supply, and depth are ideal.
Seasonal variations in biomass, growth rate and production rate of the small cyclopoid copepod Oithona davisae in a temperate eutrophic inlet
The seasonal variations in biomass, somatic growth rate and productlon rate of the small cyclopoid copepod Oithona davisae in Fukuyama Harbor, a eutrophic inlet of the Inland Sea of Japan, found that the carbon biomass of the population was lowest in early spring and increased exponentially in early summer.
Is global ocean sprawl a cause of jellyfish blooms
Jellyfish (Cnidaria, Scyphozoa) blooms appear to be increasing in both intensity and frequency in many coastal areas worldwide, due to multiple hypothesized anthropogenic stressors. Here, we propose
Seasonal population dynamics and production of Microsetella norvegica, a widely distributed but little-studied marine planktonic harpacticoid copepod
Investigation of the seasonal population dynamics and production of M. norvegica in the central part of the Inland Sea of Japan found that its reproduction was confined to the warm season between May and November, whilst its population was represented by adults, mainly large females.
Temperature-dependent development and growth of Calanus sinicus (Copepoda: Calanoida) in the laboratory
The calanoid copepod Calanus sinicus was reared in the laboratory under excess food conditions, and its development and growth rates were measured at various temperatures. Egg development time (DH,
