Overview of Decadal Ecosystem Changes in the Western Arabian Sea and the Occurrence of Algal Blooms

Paul J. H. Harrison, Sergey A Piontkovski, Khalid Al Hashmi · Journal of Agricultural and Marine Sciences · 2019 · 10.24200/jams.vol23iss0pp11-23

Gradual decadal changes have taken place in the Western Arabian Sea over the last 50 years. These changes have affected wind speeds, atmospheric and sea surface temperature, thermohaline stratification, shoaling of the oxycline, and dust/iron inputs. A decrease in nitrate supply of the photic layer have caused an incre …

Fish landings and Oman shelf area

Sergey A Piontkovski, H.E. Hamed S. Al-Oufi, Nadir M. Al-Abri · Journal of Agricultural and Marine Sciences · 2016 · 10.24200/jams.vol21iss0pp25-32

Data from five field surveys carried out along the shelf in the 20-250m depth range and historical data on artisanal fishery were analyzed. A positive linear relationship between the demersal fish biomass and the shelf area was pronounced for a certain (intermediate) stratum only: 50-100m. No statistical link was found …

Zooplankton of Oman Coastal Waters

Sergey A Piontkovski, Asila Al-Maawali, Ward Al-Muna Al-Manthri et al. · Journal of Agricultural and Marine Sciences · 2014 · 10.24200/jams.vol19iss0pp37-50

Monthly sampling during daytime was carried out in 2007-2011 at Bandar Al-Khyran (23.51oN, 58.72oE) which is the largest semi-enclosed bay on the southern end of the Sea of Oman with about 4 km2 in surface area and an average depth of 10 m. Zooplankton were represented by Copepoda (79%), Cladocera (9%), Oikopleuriddae …

Spatial-Temporal Distribution of the Palinurid and Scyllarid Phyllosoma Larvae in Oman Coastal Waters

Sergey Khvorov, Sergey A Piontkovski, Elena Popova · Journal of Agricultural and Marine Sciences · 2012 · 10.24200/jams.vol17iss0pp53-60

The Bongo Net samples collected between 2005 and 2008 in the Sea of Oman and in the north-western part of the Arabian Sea (near Massirah Island) were analyzed, for a pilot assessment of seasonal and spatial distribution of the phyllosoma larvae. In the samples collected, 84% of all phyllosoma larvae were from the famil …
