Diets of Obscure Puffer(Takifugu obscurus)and Ocellated Puffer(Takifugu ocellatus)during Spawning Migration

Study of spawning season and spawning ground of soboor (Tenualosa ilisha, Ham. Bunch., 1822) during its migration in Khuzestan rivers

During 12 months of sampling, from 17 stations, 327 specimens of Soboor fish Tenualosa ilisha, including 120 females, 113 males and 86 immature were caught. Total length (TL) of the fishes was 120-500mm. Maximum diameters of soboor ova 0.795mm and the ova with diameter more than 0.7 mm released at one spawning round. Temporal and spatial distribution of ova diameter corresponding to GSI changes...

Spawning Migration of the European Eel

Oceanic spawning migration of the European eel (Anguilla anguilla).

European eels (Anguilla anguilla) undertake a approximately 5000-kilometer (km) spawning migration from Europe to the Sargasso Sea. The larvae are transported back to European waters by the Gulf Stream and North Atlantic Drift. However, details of the spawning migration remain unknown because tracking eels in the Atlantic Ocean has, so far, eluded study. Recent advances in satellite tracking en...

Oxidative stress in Pacific salmon (Oncorhynchus spp.) during spawning migration.

The energetic and physiological challenges of spawning migrations in semelparous Pacific salmon (Oncorhynchus spp.) have been well characterized. However, the accompanying costs associated with oxidative stress during this nonfeeding migration and the potential connection to senescence have not been explored. Oxidative stress is caused by an imbalance between free radical production and absorpt...
