The Indian mackerel (Rastrelliger kanagurta) is one of the commercial pelagic fish in the Persian Gulf and Oman Sea. In the current research, food preference index (FP), fullness index (FI), and stomach contents of Rastrelliger kanagurta were evaluated to assess the quantity and type of food which this species consumes in the study area. The samples were collected randomly from Bandar - Abbas a...

Citation: Kandasamy S and Weis P (2015) Commentary: Biogeochemical analysis of ancient Pacific Cod bone suggests Hg bioaccumulation was linked to Paleo sea level rise and climate change. Over the last 21,000 years, continuous and pulsed sea level rises from its glacial minimum of ∼120 m below the present sea level have affected the continental configuration of Earth's surface and thus land-sea ...

This paper is evolved to have insight of Plankton-Nutrients interactions in the presence of delay in the growth term of phytoplankton species .The conditions for asymptotic stability about endemic equilibrium are derived in the absence of delay.The Nyquist criteria is used to estimate the length of delay to preserve stability .Analytic criterion for the existence of hopf-bifurcation is also dis...

In this paper, we present a methodology for aquatic ecosystem modeling. We based our model on the holarchic (non directional hierarchic) nature of the ecosystems. Aquatic ecosystems are crossed by structuring fluxes (light radiation, mass transport, etc.) which confer multi-level of emergent organizations. Elsewhere, a part of aquatic ecosystems are species organizations called food chain. Thes...
