A 3 yr study was conducted on the feeding biology and reproductive strategies of Acanthurus nigrofuscus (Acanthuridae, Teleostei) found along the coral reefs of the Gulf of Aqaba and forming there the major biomass of algivorous fish. The diet of this surgeonfish is based on algae selected from turf communities growing on subtidal rocky surfaces. At some sites A. nigrofuscus form schools that migrate daily from nocturnal refuges in coral reefs to foraging sites on the intertidal, covering… 

The Reproductive Behavior of Acanthurus nigrofuscus (Forskal) and other Surgeonfishes (Fam. Acanthuridae) off Eilat, Israel (Gulf of Aqaba, Red Sea)

The reproductive behavior of Acanthurus nigrofuscus, a common surgeonfish of the Red Sea, is described for two overlapping populations inhabiting the coral reefs off Eilat, Israel and compared with populations of the same and related species of surgeonfishes at widely distributed locations in the Indo-Pacific.

Rapid data collection and assessment of the biology of Acanthurus nigrofuscus at Woleai Atoll, Micronesia

Traditional community fishing methods commonly employed in the tropical Pacific were used to generate information on the fishery biology of Acanthurus nigrofuscus at Woleai Atoll, Micronesia, over a short time period, finding sexually mature fish were present in all size classes above the minimum capture length and spawning activity was greatest during the period of the full moon.

Response of herbivorous fishes to crown-of-thorns starfish Acanthaster planci outbreaks. I. Substratum analysis and feeding ecology of Acanthurus nigrofuscus and Scarus frenatus

A large-scale comparative study of 3 crown-of-thorns starflsh impacted reefs and 3 non-impacted reefs in the central reglon of the Great Barner Reef was undertaken to investigate a long-term functional response of hcrbivorous fish to a potentially greater food source in the form of increased abundances of turf algae on COTS affected reefs.

Spatial and foraging behaviour, diet and morphogenesis of postlarvae and juveniles of Pempheris vanicolensis in the Gulf of Aqaba, Red Sea

Post-settlement ecology, ontogenesis of morphology and behaviour were studied in juvenile Pempheris vanicolensis in the Gulf of Aqaba, Red Sea, finding a rhomboid body shape, typical for this species, was formed.

Aspects of the spawning of western Atlantic butterflyfishes (Pisces: Chaetodontidae)

Chaetodon aculeatus spawned near the time of sunset over objects on the reef as single female/male pairs or as two females and one male, with pair spawning in rapid succession, and it is uncertain whether any lunar periodicity to spawning exists.

Influence of season, ontogeny and tide on the diet of the temperate marine herbivorous fish Odax pullus (Odacidae)

The diet of the temperate marine herbivorous fish Odax pullus (Pisces: Odacidae) was examined using gut-content analysis followed by principal-component analysis and analysis of variance, and a major ontogenetic shift in diet was observed.

Some aspects of the reproductive biology ofBarbus spp.,Capoeta damascina and their hybrids (Cyprinidae, Teleostei) in Israel

The reproductive biology and gonad cycle of three Cyprinid fish species in the upper Jordan River system of Israel were studied by monthly sampling over a two-year period, finding the reproductive activity of the three species to peak from January to April.

Metabarcoding as a tool to examine cryptic algae in the diets of two common grazing surgeonfishes, Acanthurus triostegus and A . nigrofuscus

Surgeonfishes (Acanthuridae) are an important group of herbivores that are abundant on reefs globally. Acanthurids consume macroalgae that can compete with corals for space, turf algae that can



On the spawning behavior and spawning cycles of eight surgeonfishes (Acanthuridae) from the Indo-Pacific

Seven species, all fairly exclusively benthic feeding, defended feeding territories to some extent, and some of them formed territorial groups composed of 1 male + ≥ 1 female, and both sexes appeared to be nonterritorial, except that males defended temporary spawning territories.

Contribution to the Biology of the Convict Surgeonfish of the Hawaiian Islands, Acanthurus triostegus sandvicensis

The present paper constitutes a report of a study made during 195255 upon the life history and the ecology of one Hawai ian subspecies of this genus, A .

Oogenesis in five species of grey mullets (Teleostei, Mugilidae) from natural and landlocked habitats.

The seasonal histological changes in the ovaries of specimens of five species of Mugil caught in natural habitat were compared with those of specimens in fish ponds and Lake Tiberias to study the Gonado-Somatic Index (GSI) of the various species of mullets.

A new fat body associated with the gonad of surgeonfishes (Acanthuridae: Teleostei)

The composition, arrangement and dynamics of the fat bodies suggest that they support the active gonad during a spawning season that lasts, in one species, from May to September.

A unique symbiosis in the gut of tropical herbivorous surgeonfish (acanthuridae: teleostei) from the red sea.

Herbivorous surgeonfish (Acanthurus species) in the Red Sea harbor gut symbionts that include bacteria, trichomonadid flagellates, and a peculiar putative protist that attains densities of 20,000 to

Ecology and Physiology of Sex Reversal in Anthias squamipinnis (Peters), (Teleostei: Anthiidae)

In the strategy of propagation in teleost fishes, intersexuality and sex-reversal seem to be no less important than “normal”, genetically fixed bi-sexual reproduction. The more we know about these

Oogenesis and spawn-formation in the pigmy lion fish Dendrochirus brachypterus (Pteroidae)

Oogenesis in the lion fish enables the growing egg cells to move away from the egg-producing surface, thus making space available for the ovary to produce more eggs, which should have a survival value for these fish.

Contrasts in Social Behavior between Central American Cichlid Fishes and Coral-reef Surgeon Fishes

The social systems and related behavior of cichlid and surgeon fishes are compared and Wickler's classification of reproductive types within the Cichlidae is shown to be no advance over the previous dichotomy of substrate and mouthbreeding species.

The comparative ultrastructure of the egg membrane and associated pore structures in the starry flounder, Platichthys stellatus (Pallas), and pink salmon, Oncorhynchus gorbuscha (Walbaum)

Differences in egg membrane structure with reference to contrasting ecological conditions in which the eggs normally develop may be reflected by the thin membrane and simple lamellar structure in the pelagic egg of the starry flounder, and the thick membrane and complex lamellars structure inThe demersal egg ofThe pink salmon.
