The zooplankton biomass and distribution were studied during two oceanographic cruises in NE part of the Persian Gulf in autumn 2012 (November) and summer 2013 (August) with 300 μmmesh net. Zooplankton samples were analyzed for biomass content. Zooplankton biomass expressed as mg m-3 dry wt., was greatest during summer cruise (mean of 18.8 ± 4.6 mg m-3 dry wt.). The mean zooplankton bioma...

survey on zooplankton composition was studied during june 2015 to march 2016, by selecting six stations along the coastal waters of bushehr (the northwest persian gulf). twenty four zooplankton taxa were identified, and the different zooplankton groups represented twenty-one families. copepoda was recorded with the most abundance (53.30 %) followed by malacostraca (32.87 %), which in turn was f...

both heliophysical and anthropogenic (wastewater) effects on zooplankton biomass and abundance of the imandra lake (the largest subarctic lake at kola peninsula, russia) were investigated during the 1990 - 2003 period. we used different indexes of solar activity (sunspot numbers and uv- radiation values) as heliophysical factors. information about uv- radiation values was derived from satellite...

The zooplankton community and environmental conditions were monitored during Dec. 2012 PG-GOOS (Persian Gulf and Gulf of Oman Oceanographic Study) oceanographic cruise on board N/V Ja Nayband throughout the northwestern part of the Persian Gulf. Data of temperature, salinity, depth and pH as well as zooplankton community composition and abundance were collected from 17 stations. The zoopla...

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...

Zooplankton concentrations are known to vary by as much as an order of magnitude over a lunar cycle. Here, we conducted an experiment to determine the effect of ambient zooplankton concentrations over a lunar cycle on feeding rates of the corals Pavona gigantea (Verrill) (mounding coral, 3.0 mm diameter polyps) and Pocillopora damicornis (Linnaeus) (branching coral, 1.0 mm diameter polyps) in s...

temporal and spatial variation of zooplankton abundance, composition and biomass were examined on the chabahar bay, oman sea. the chabahar bay, a subtropical and semi-enclosed bay, provides an ideal breeding ground for many fish and shellfish. five stations were investigated along the bay. this area is under the influence of the indian ocean seasonal monsoons. zooplankton was collected with ver...

Zooplankton play an important role in the trophic dynamics of coral reef ecosystems. Detailed vertical and temporal distribution and biomass of zooplankton were evaluated at four heights off the bottom and at six times throughout the diel cycle over a coral reef in the Florida Keys (USA). Zooplankton abundance averaged 4396 +/- 1949 SD individuals m(-3), but temporal and spatial distributions v...

This study was carried out to determine seasonal variation and zooplankton community structure in Karataş Lake, Southern Turkey. Zooplankton samples were collected seasonally between 2002 and 2003 in two stations using a zooplankton net of 55-µm mesh size. A total of 42 taxa were identified, including 19 taxa (45.2 %) Rotifera, 16 taxa (38.1 %) Cladocera, and 7 taxa (16.7 %). Copepoda. Among th...
