Diet composition and prey selection of the introduced grouper species peacock hind (Cephalopholis argus) in Hawaii
The grouper species peacock hind (Cephalopholis argus) (Serranidae: Epinephelinae), a reef fish predator that is native over most of the IndoPacific region, was introduced to the Main Hawaiian Islands (MHI) in 1956 as part of an introduction program of snapper and grouper species intended to enhance nearshore fisheries (Randall, 1987). Today, this non-native predator occupies a dominant positio...
متن کاملElevated size and body condition and altered feeding ecology of the grouper Cephalopholis argus in non-native habitats
In 1956, the shallow-water grouper Cephalopholis argus was introduced from Moorea (French Polynesia), where grouper diversity (14 species) is high, to the Main Hawaiian Islands (MHI), where only 2 rare native deep-water groupers occur. In this non-native environment, the species has flourished and has become the dominant apex predator on many reefs. In the present study, a comparison of non-nat...
متن کاملPredator-Induced Demographic Shifts in Coral Reef Fish Assemblages
In recent years, it has become apparent that human impacts have altered community structure in coastal and marine ecosystems worldwide. Of these, fishing is one of the most pervasive, and a growing body of work suggests that fishing can have strong effects on the ecology of target species, especially top predators. However, the effects of removing top predators on lower trophic groups of prey f...
متن کاملLength-Based Assessment of Coral Reef Fish Populations in the Main and Northwestern Hawaiian Islands
The coral reef fish community of Hawaii is composed of hundreds of species, supports a multimillion dollar fishing and tourism industry, and is of great cultural importance to the local population. However, a major stock assessment of Hawaiian coral reef fish populations has not yet been conducted. Here we used the robust indicator variable "average length in the exploited phase of the populati...
متن کاملPatterns in reef fish assemblages: Insights from the Chagos Archipelago
Understanding the drivers of variability in the composition of fish assemblages across the Indo-Pacific region is crucial to support coral reef ecosystem resilience. Whilst numerous relationships and feedback mechanisms between the functional roles of coral reef fishes and reef benthic composition have been investigated, certain key groups, such as the herbivores, are widely suggested to mainta...
