Hysterothylacium fabri is commonly reported in various Mediterranean fish. However, there no data on the mitochondrial ribosomal RNA (rrnS) gene sequence of H. larvae Sea waters. Therefore, we aimed to reveal molecular characterization based rrnS current study. Firstly, fourth stage were identified at parasitological examination from Mullus barbatus Sea. Morphologically herein also supported by...

Hysterothylacium geschei n. sp. (Nematoda, Anisakidae) is described from the intestine of Cauque mauleanum (Steindachner) (Pisces: Atherinidae) from Lake Panguipulli (39 degrees-43'S; 72 degrees-13'W), Chile. Eleven (78.6%) out of 14 fish were infected, with a mean intensity (range) of 14.4 (1-55) worms. The new species can be differentiated from the two previously described species of freshwat...

A total of 301 blue whiting, Micromesistius poutassou Risso, 1826, ranging in length from 17 to 28 cm, from Motril Bay (Mediterranean coast, south Spain) were examined for anisakid nematodes, as these fish are common items in the Spanish Mediterranean diet. Three anisakid species were morphologically identified with a total prevalence of 10.63%. Anisakis simplex s.l. Rudolphi, 1809 had a preval...

In this study, nematodes were first reported in the amphipods, Ischyrocerus commensalis, collected from introduced and commercially important red king crabs, Paralithodes camtschaticus, coastal Barents Sea July 2022. Commensal amphipods registered on all crabs captured (n = 70, prevalence 100%). Further laboratory analysis revealed that 11 out of 467 amphipod individuals (prevalence 2.4%) harbo...

In this study, two thermal-tolerant mutants of Chlorella sp. MT-7 and MT-15, were isolated. In indoor cultivation, specific growth rate (micro, d(-1)) of the mutants were 1.4 to 1.8-fold at 25 degrees Celsius and 3.3 to 6.7-fold at 40 degrees Celsius higher than those of wild type. The carbon dioxide fixation rate of both microalgal mutants was also significantly higher than that of wild type. ...
