摘要

Abstract

Fishing activities can alter the structure of marine food webs by the selective removal of some species. The changes in the marine food webs of the Hormuzgan waters of the Persian Gulf

Iran were assessed

based on estimates of the mean trophic index (MTI) and Fishing in Balance index (FiB)

and on landing profile of the exploited marine community (49 species) during the period

2002–2011. The total landings (Y t) (R=0.88

P<0.001) increased gradually while the Y t of carnivores has slightly declined

and the Y t of herbivores

detritivores and omnivores has increased. Consequently

the MTI significantly decreased (R =-0.69

P<0.05) at a rate of 0.11 during this decade. The MTI showed a decreasing trend

which indicates exploitation of marine resources. The FiB index also showed a downward trend and negative values from 2002 to 2009

which may be associated with unbalanced structure in the fisheries

but an upward trend from 2009 to 2011. The time variation of the landing profile showed two periods with significant diff erences in their species composition (R=0.88; P =0.005)

and based on analysis of similarity

species have been identified as discriminator species

namely Thunnus albacores and Benthosema pterotum. Results indicate that changes in MTI reflected changes in the Hormuzgan landing structure. The examination of the MTI

FBI

and landing profile (LP) temporal pattern suggests that the status of fishery resources in Hormuzgan inshore waters is overexploited

and provides evidence of the probability that a fishing down process is occurring in this area

and that this trend may continue in the long-term. Therefore

environmental fisheries management and conservation programs should be prioritized for these valuable resources.
