“…Their analyses provided a conceptual basis for ranking human pressures relative to their expected relevance for fish in transitional waters. In order to further confirm the relationship between fish-quality attributes and pressures, two WFD-compliant indices (from the Spanish Basque Country (AZTI's Fish Index (AFI), Uriarte & Borja (2009)) and Portuguese estuaries [Estuarine Fish Assessment Index (EFAI), Cabral et al, 2012)] were related to a set of pressures acting in these water bodies, while also considering their hydro-morphological descriptors. AFI related to different variables is: Hence, the deeper the estuary, and the shorter the residence time, the pressure index and the channelled ports within the estuary, then the higher the AFI values would be, indicating higher ecological quality.…”

“…Fish assemblages in European estuaries are typically dominated by either migrant or straggler marine species, i.e. irregular visitors with no apparent estuarine requirements (Elliott and Dewailly 1995, Thiel and Potter 2001, Maes et al 2005, Pombo et al 2007, Franco et al 2008, Cabral et al 2012.…”

SUMMARY: In the present study, the seasonal and inter-annual fish assemblage structure of intertidal mudflats of Indian Sundarbans was analysed during tidal cycles. A total of 31 fish species belonging to 22 families and 9 orders were collected during high tide, whereas only 12 were recorded during low tide. Fish assemblage descriptions were based on several community descriptors, namely diversity (H′), species richness (S), species dominance (D), and species evenness (J) and on an ecological guild classification. A canonical correspondence analysis (CCA) was performed to evaluate the relationship between estuarine habitat and fish assemblages in the mudflat habitat during inundated and exposed conditions. All the diversity indices showed marked seasonal and inter-annual variations. Temporal variations were also found in fish assemblage structure in both tidal conditions. Estuarine species were the most important ecological guild of the mudflats during both high and low tides. Of all the abiotic variables examined, CCA showed that salinity, pH and nutrients were the most important influencing fish assemblage during high tide. Total dissolved solids, water temperature and salinity were significant during low tide. Considering the importance of mudflats in supporting fish diversity, the present study emphasizes the increased efforts for conservation of this habitat in the Indian Sundarbans.Keywords: ichthyofaunal diversity, seasonal variation, tidal variation, mudflats, Bray-Curtis similarity, CCA.

Las comunidades se describieron varios descriptores: diversidad (H′), riqueza de especies (S), dominancia de especies (D) y uniformidad de especies (J) y una clasificación ecológica de comunidad. Se realizó un análisis de correspondencia canónico (CCA) para evaluar la relación entre hábitat estuárico y comunidades de peces durante condiciones inundadas y expuestas. Todos los índices de diversidad mostraron marcadas diferencias estacionales e interanuales. También se encontraron variaciones temporales en la estructura del conjunto de peces en tanto las condiciones de la marea. Especies estuarinas (ES) fue el grupo ecológico más importante de las marismas de Sundarbans tanto durante la marea alta como en la baja.Palabras clave: diversidad íctica, variación estacional, variación de marea, marismas, similitud de Bray-Curtis, CCA.

“…The fish communities in the estuary represent all different trophic levels in the food chain (Elliott 2007;Harrison and Whitfield, 2012;Sreekanth 2015a). The estuary has provided shelter to 126 ecologically vulnerable species (Musick, 1999;Cheung 2005) and species of fisheries importance were abundant in the estuary similar to other estuarine counterparts (Jaureguizar 2004;Cabral 2012;Franco 2012;Sreekanth 2015a). …”
