Sex Change in Protogynous Fish Red-Belted Anthias Pseudanthias rubrizonatus (Serranidae) in Kagoshima Bay, Japan

The Serranidae are well known for protogynous sex change. The red-belted anthias Pseudanthias rubrizonatus inhabits Kagoshima Bay. We aimed to estimate the body size and age of P. rubrizonatus

Sexual Lability in Teleosts: Developmental Factors

It is proposed here that in teleosts the brain is the initial site of sexual differentiation, and that the pattern of differentiation in the brain determines the fate of the gonads.

Switches, stability and reversals in the evolutionary history of sexual systems in fish

It is shown that gonochorism is the likely ancestral condition in teleost fish, and it is proposed that future studies should incorporate mating systems, spawning behaviours, and the diversity of sex determining mechanisms, supporting that simultaneous hermaphroditism cannot evolve directly from separate sexes but requires sequential herm Aphrodite as an intermediate step.

Evolutionary Transitions in the Sexual Patterns of Fishes: Insights from a Phylogenetic Analysis of the Seabasses (Teleostei: Serranidae)

Results from this study suggest that sexual patterns in fishes can evolve in several directions within single lineages and do not require functional intermediates.

A Phylogenetic Test of the Size‐Advantage Model: Evolutionary Changes in Mating Behavior Influence the Loss of Sex Change in a Fish Lineage

It is shown that the loss of sex change within a lineage of reef fishes is influenced by evolutionary changes in two traits related to their mating behavior: mating group structure and sperm competition intensity.

Social system of an inshore stock of the red hind grouper,Epinephelus guttatus (Pisces: Serranidae)

SynopsisAccording to sex allocation theory, the decision by a female in protogynous fish species to change sex or not should be influenced by, among other things, the mating sex ratio during spawning

Behavioral influences on gene structure and other new ideas concerning sex change in fishes

The interpretation of experiments, designed to reveal whether sex change is induced behaviorally, can influence the type of physiological mechanism the authors propose to underlie sex change, which is likely to involve CNS, hypothalamus, pituitary, and gonad.

Evolutionary ecology of sex change

This thesis tests a priori predictions regarding the social and ecological context in which selection favours sex change and/or the production of alternative mating strategies with a field study and laboratory experiment using populations of the marine teleost fish Coryphopterus personatus.

Endocrine and environmental aspects of sex differentiation in fish

Although steroids and steroidogenic enzymes are probably not the initial triggers of sex differentiation, new data, including molecular approaches, have confirmed that they are key physiological steps in the regulation of this process.

Protogynous hermaphroditism in the half-banded sea perch, Hypoplectrodes maccullochi (Serranidae)

The half-banded sea perch, Hypoplectrodes maccullochi (Serranidae) exhibits protogynous hermaphroditism, based on the presence of transitional individuals collected from rocky reefs along the coast of New South Wales, Australia, which conforms with the pattern of reproduction evident within the genus Hypopleclrodes.



Sex Reversal in the Serranid Fish, Sacura margaritacea. II:Seasonal Variations in Gonads in Relation to Sex Reversal

The present investigation on the sex reversal in Sacura margaritacea was based on 335 specimens kindly supplied to the writer by Dr. Tokiharu Abe of the Tokai Regional Fisheries Research Laboratory.

Anthias conspicuus sp. nova (Perciformes: Serranidae) from the Indian Ocean, with Comments on Related Species

A synopsis of diagnostic characters of valid species plus a list of nominal species of Anthias which have been described or reported from the Indo-Western Pacific region are presented.

Ecology and behavior of Anthias squamipinnis (peters, 1855) (Anthiidae, Teleostei) in the coral habitat of eilat (Red Sea)

Anthias squamipinnis (Anthiidae, Teleostei), a sexually dimorphic coral fish, is found in large swarms along the western coast of the Gulf of Aqaba. Each swarm is permanently bound to a particular

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

Social Control of Sex Reversal in a Coral-Reef Fish

Males of Labroides dimidiatus control the process of sex reversal within social groups by actively dominating them and death of the male releases this suppression and the dominant female of the harem changes sex immediately.
