For animals that reproduce in water, many adaptations in life-history traits such as egg size, parental care, and behaviors that relate to embryo oxygenation are still poorly understood. In pipefishes, seahorses and seadragons, males care for the embryos either in some sort of brood pouch, or attached ventrally to the skin on their belly or tail. Typically, egg size is larger in the brood pouch...

The presently reported study was intended to describe the current range of an Atlanto–Mediterranean fish, black-striped pipefish, Syngnathus abaster Risso, 1827, in Ukrainian waters and analyze biological tags (size parameters parasites) its different populations. parasitological survey carried at five localities, including one marine site, two deltaic zones, localities middle Dnipro basin. pro...

The deterioration of coastal habitats cascades to the decline associated fauna by reducing trophic resource availability, shelter from predators and nursery grounds. biogenic habitat structure, such as in kelp forests, coral reefs, mangroves or seagrass beds, often causes a local increase water flow velocity wave exposure. impact this change hydrodynamics on energy expenditure animals is largel...

Syngnathids are vulnerable fishes closely associated with seaweeds and seagrass, which provide shelter food resources. Even though most syngnathids commonly feed on small crustaceans, the feeding regimes may differ depending species prey availability. This is first monitoring study to explain syngnathid abundances dietary within macroalgal beds in Cíes Archipelago (Atlantic Islands Marine Natio...

Occurrence and distribution of larval and juvenile fish was investigated in nearshore waters of the southeastern Caspian Sea including the Gorgan Bay. Samples were collected during seven surveys using a fine mesh beach-seine in five sampling sites from July 2014 to June 2015. A total of 15500 individuals mostly juvenile were captured, representing 18 species from 8 families. Most juveniles belo...
