Coral reef fishes are exploited without the knowledge of their sustainability and their possible effect in altering the community structure of a coral reef ecosystem. Alteration of the community structure could cause a decline in the health of coral reefs and its services. We documented the coral community structure, status of live corals and reef fish assemblages in Palk Bay at the reef fishin...

Fear of predators (‘fear effects’) is an important determinant foraging decisions by consumers across a range ecosystems. Group size one the main behavioural mechanisms for mitigating fear effects while also providing benefits to group members. Within coral reef ecosystems, have been shown influence feeding rates herbivorous fishes, key functional that prevents macroalgal overgrowth. Yet, how a...

Lunar cycle-associated physiology has been found in a wide variety of organisms. Studies suggest the presence of a circalunar clock in some animals, but the location of the lunar clock is unclear. We previously found lunar-associated expression of transcripts for Cryptochrome3 gene (SgCry3) in the brain of a lunar phase-responsive fish, the Goldlined spinefoot (Siganus guttatus). Then we propos...

Gelatin isolated from limed split wastes can be a high value product due to its special characteristics and has many potential future applications in Food, functional additives, Food and pharmaceutical industries. Concentrations of sodium hydroxide, sulfuric and acetic acids used in processing gelatin from Narrow barred, Carcharhinus Leucas, Siganus Sutor and Indo Pacific king mackerel skins af...

Information on the initial stages of dispersal and settlement are of great interest in understanding the dynamics of biological invasions and in designing management responses. A newly settled population of the Lessepsian rabbitfish migrant Siganus luridus, that arrived in Linosa Island (Sicily Strait) in 2000, offered a unique opportunity to examine the genetic variability of the early phase o...

Fishes of the tropical Indo-Pacific family Siganidae comprise 28 species, characterized by their body proportions and their colour patterns. A mitochondrial phylogeny of 20 Siganidae species was produced to infer their evolutionary history. Three distinct, major clades were found, that also correspond to the early radiation of the family into three major ecological types: fusiform species that ...

Hsiu-Hui Shih and Ming-Shiou Jeng (2002) Hysterothylacium aduncum (Nematoda: Anisakidae) infecting a herbivorous fish, Siganus fuscescens, off the Taiwanese coast of the Northwest Pacific. Zoological Studies 41(2): 207-214. Hysterothylacium aduncum (Rudolphi, 1802) infecting a herbivorous fish, Siganus fuscescens, and 1 invertebrate zooplankton, a chaetognath, is reported off the Taiwanese coas...
