Diets are a critical factor in the artificial production of lobster larvae, yet knowledge diet requirements spiny especially at its early life stages is rarely investigated. Thus, present study aimed finding potential diets larva by analyzing stomach content wild-caught ornate lobster, Panulirus ornatus, three different stages: puerulus, post-puerulus, and juvenile using eDNA metabarcoding. The...

Copepods are the main zooplankton assemblages in most tropical and semi-tropical estuaries. In this research, copepod population dynamics were investigated in Helleh River estuary, Persian Gulf during four seasons beginning from summer 2011 to spring 2012.  Samples were taken using plankton net with mesh size of 140 µm and vertical towing from 5 fixed-stations in mid-season. Results showed that...

The ecosystem of the Caspian Sea have been strikingly changed by human activities. This area has undergone significant ecological alterations and serious environmental degradation since the beginning of 1990s. The impact of fish cage culture on the zooplankton community was studied in the southwestern Caspian Sea, off Jafrud during January to April 2013. A total of 12 zooplankton belonging to 9...

This paper describes the diets of 201 larvae of Atlantic mackerel Scomber scombrus L. collected from Long Island Sound, New York (USA) during May-June 1982 and 1983. First-feeding larvae (3.5 mm in length) were phytophagous. The diets of larvae 4.5 mm were composed of the nauplii of Acartia hudsonica, Temora longicornis and Pseudocalanus sp. Larvae > 5 mm ate some copepodites of A. hudsonica an...

Mariculture is considered a future economic source for Indonesia. However, this practice may degrade the surrounding ecosystem by decreasing water quality, including plankton community. This study aimed to determine community structure of (phytoplankton and zooplankton) in mariculture sites. Study sites were selected based on activities Research Center Marine Terrestrial Bioindustry (PRBILD-BRI...
