Predicting single and mixture toxicity of petrogenic polycyclic aromatic hydrocarbons to the copepod Oithona davisae.
In the present study, the acute toxicity of 10 polycyclic aromatic hydrocarbons (PAHs) associated with the Prestige fuel oil spill (Spain, 2002) were evaluated, either as single substances or in mixtures, in adults of the copepod Oithona davisae. All but dimethylphenanthrene had negative effects on O. davisae survival at concentrations below their water solubility, with 48-h median lethal conce...
متن کاملIntensive Cultivation of the Calanoid Copepod Oithona Rigida for Mariculture Purpose
The cyclopoida copepod Oithona rigida has good potential for mass culture as a live feed. This study was carried out to investigate the effects of salinity on density of O.rigida four ranges with 15, 25, 35 and 45 ‰ and mass cultured under four salinity levels (15,25,35,and 45 ‰) in 5 L fiberglass tanks over 19 days culture period. However, it is better to be cultured at salinity of 35 ‰ for ma...
متن کاملFeeding by the cyclopoid copepod Oithona similis on the microplankton assemblage in the Oyashio region during spring
Onboard incubation experiments were conducted to examine the feeding rates and selectivity of the cyclopoid copepod Oithona similis on natural assemblages of microplankton during the spring bloom in the Oyashio region. O. similis cleared ciliates at higher rates (2.8–11.9 mL copepod 1 d ) than dinoflagellates (1.4 mL copepod 1 d ), with no detectable ingestion of diatoms. Clearance increased wi...
متن کاملFeeding rates and prey : predator size ratios of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae
We studied the feeding behavior of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae in the laboratory. Functional response experiments showed that O. davisae can feed on a broad size range of prey but that high clearance rates only occur in a narrow prey size range. Neither the nauplii nor the females were able to feed on Nannochloropsis oculata (2.5 mm), but . 4 mm...
متن کاملA Eeview of the Copepod Genus Paranthessius Claus
The problem of arriving at a natural classification of the copepods has been in no small measure complicated by the repeated appearance within the group of the parasitic and commensal habit. In the cyclopoids, two sections, the Poecilostoma and the Siphonostoma, have been established and remain well differentiated on the basis of the specialization of mouth appendages correlated with parasitic ...
