Trophic Level, Food Preference and Feeding Ecology of Rachycentron canadum (Linnaeus. 1766), in Hormuzgun province Waters (Northern Persian Gulf and Oman Sea)
The aim of this study was to assess the ecological factors associated with feeding by Rachycentron canadum (cobia) in the waters of Hormuzgan Province, Iran. Specimens were collected seasonally from Sep. 2014–Sep. 2015 from the Ferdows-1 survey ship and from landing areas in the city of Bandar Abbas. A total of 577 cobia were collected (340 male, 237 female) (20–161 cm Total length). Our result...
متن کاملIncreasing preference for beef magnifies human impact on world's food web.
Bonhommeau et al.’s report, “Eating up the world’s food web and the human trophic level” (1), provides a valuable perspective on the role of human food consumption within the global ecosystem. However, the ranking of human beings at a similar trophic level as other animals downplays the effects that humans have on the Earth in comparison with other species. The sheer volume of food consumed by ...

This study examined the ecological factors associated with feeding in Rachycentron canadum (cobia) in the waters of Persian Gulf and Oman Sea. Seasonally variation of stomach condition of cobia male, females, pooled and size wise were analyzed. In general, 577 cobia were collected (340 males, 237 females) (20–161 cm Total length) from Sept. 2014 to Sept. 2015 by the Ferdows-1 survey ship and fr...
متن کاملResearch Article: Trophic dynamics analysis and ecosystem structure for some fish species of northern Oman Sea
In the present study, a trophic structure model for some fish species of the northern Oman Sea is developed through using mass balance modeling software, Ecopath with Ecosim (EwE). In this model, we simulated 16 functional groups spread across an area of 3998.20 km2 from 2017 to 2018. Mean trophic level in the area of the present study was 3.49. Values calculated for system omnivory and connect...
متن کاملPhylogenetic diversity and co-evolutionary signals among trophic levels change across a habitat edge.
Incorporating the evolutionary history of species into community ecology enhances understanding of community composition, ecosystem functioning and responses to environmental changes. Phylogenetic history might partly explain the impact of fragmentation and land-use change on assemblages of interacting organisms and even determine potential cascading effects across trophic levels. However, it r...
