Connectivity of marine habitats of Pulau Tinggi through fish diets

H. R., Singh and Norashekin K. B., . and Md. Nizam Ismail, . (2018) Connectivity of marine habitats of Pulau Tinggi through fish diets. [Proceedings Paper]

This paper reports on the fish species sampled from the mangroves, seagrass beds and coral reefs of P Tinggi in order to demonstrate connectivity of the habitats via fish diets. 78 species were sampled from 39 families utilizing gill nets of mesh sizes 1.5”, 3" & 5”. The total fish biomass was 41.2 g/m²/hr while the total density was 0.16 no/m²/ hr. The Margalef's index was 11.8, Shannon-Weiner index was 3.36, and Pielou index was 0.77. Fishes from mangroves recorded higher empty stomachs (53%) while fishes from the coral habitat showed higher full and gorged stomachs (22%). The important diet types were decapoda (31%), teleost (27%), plant matter (10%) and unidentified materials (14%). Fishes showed diet partitioning between habitats where different food categories were consumed in different habitats, especially for the carnivorous fish. Connectivity of habitats through diets was demonstrated by 7 fish species sampled.

Abstract

This paper reports on the fish species sampled from the mangroves, seagrass beds and coral reefs of P Tinggi in order to demonstrate connectivity of the habitats via fish diets. 78 species were sampled from 39 families utilizing gill nets of mesh sizes 1.5”, 3" & 5”. The total fish biomass was 41.2 g/m²/hr while the total density was 0.16 no/m²/ hr. The Margalef's index was 11.8, Shannon-Weiner index was 3.36, and Pielou index was 0.77. Fishes from mangroves recorded higher empty stomachs (53%) while fishes from the coral habitat showed higher full and gorged stomachs (22%). The important diet types were decapoda (31%), teleost (27%), plant matter (10%) and unidentified materials (14%). Fishes showed diet partitioning between habitats where different food categories were consumed in different habitats, especially for the carnivorous fish. Connectivity of habitats through diets was demonstrated by 7 fish species sampled.
