Food Preference of Purple-Spotted Bigeye (Priacanthus tayenus Richardson 1846) in Northern Coast of Java, Indonesia
Diet is one of the essential information used in the management of fisheries resource. The objective of this study was to assess the dietary preferences, index of preponderance, trophic level, food niche breadth, and food overlap of purple-spotted bigeye (Priacanthus tayenus) caught from the northern coast of Java, Indonesia. A total of 407 fish samples were collected from July to October 2023. Each fish sample was measured for total length and body weight. Fish were then dissected to determine sex, gut length, gut volume, and diet composition. Data analysis included relative gut length, diet composition, frequency of occurrence, trophic level, index of preponderance, food niche breadth, and food overlap. The result showed that the purple-spotted bigeye is a carnivorous fish (trophic level ranges from 3.88 to 4.18), whose main food is fish and shrimp. Based on the niche breadth value, purple-spotted bigeye from East Java were more diverse in finding food (niche breadth = 0.26) than from West Java (niche breadth = 0.06) and Central Java (niche breadth = 0.09). The purple-spotted bigeye species from West Java and Central Java exhibited a high level of competition in their search for food, as indicated by a food overlap value of 0.998.
期刊介绍：
Marine Ecology publishes original contributions on the structure and dynamics of marine benthic and pelagic ecosystems, communities and populations, and on the critical links between ecology and the evolution of marine organisms.
The journal prioritizes contributions elucidating fundamental aspects of species interaction and adaptation to the environment through integration of information from various organizational levels (molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, palaeontology and modelling) as viewed from an ecological perspective. The journal also focuses on population genetic processes, evolution of life histories, morphological traits and behaviour, historical ecology and biogeography, macro-ecology and seascape ecology, palaeo-ecological reconstruction, and ecological changes due to introduction of new biota, human pressure or environmental change.
Most applied marine science, including fisheries biology, aquaculture, natural-products chemistry, toxicology, and local pollution studies lie outside the scope of the journal. Papers should address ecological questions that would be of interest to a worldwide readership of ecologists; papers of mostly local interest, including descriptions of flora and fauna, taxonomic descriptions, and range extensions will not be considered.
