SynopsisThe development of the sensory barbels of the tropical goatfish, Upeneus tragula (Mullidae), was examined from their first appearance early in planktonic life through to the reef-associated juvenile period. The structure of the barbel was examined histologically and found to represent an outgrowth of the gustatory (taste) system, composed of at least 50% sensory tissue at settlement. Abrupt changes in morphology were found to be coincident with the 6–12 h settlement period: barbels… 

Otolith morphology, age, and growth of freckled goatfish Upeneus tragula (Mullidae) in the coastal zone of Vietnam

Age composition of the populations from the coastal zone of Vietnam (Nha Trang and Ha Long bays) is assessed based on the calculation of daily increments, and the growth rate of the fishes is characterized by a substantial variation.

Quantitative changes in the otolithic organs of the inner ear during the settlement period in European hake Merluccius merluccius

A quanti- tative inversion in the percentage of the sensory epithelia area and the number of hair cells between the saccule and utricle over this time period is demonstrated, which could be related to ecological changes in mobility and feeding.

Life-history transitions of the coral-reef fish Elacatinus lori.

This study provides the first comprehensive description of these life-history transitions for a species within the genus Elacatinus, the most speciose genus of fishes on Caribbean coral reefs.

Delayed metamorphosis of a tropical reef fish ( Acanthurus triostegus ) : a field experiment

Larval duration of a demersal fish is a product of its genotype, its larval environment and the capacity of the species to delay metamorphosis. Circumstantial evidence has led to the hypothesis that

Ontogeny of the Digestive and Feeding Systems in the Anemonefish Amphiprion Melanopus

The rapid development found in this species may be a specialisation to enhance the return of larvae to a patchy and highly specific settlement habitat.

Reproduction of freckled goatfish Upeneus tragula (Mullidae) in the coastal zone of Vietnam

Features of reproduction are described in the tropical representative of the family Mullidae freckled goatfish Upeneus tragula from southern Central Vietnam (Nha Trang Bay) and North Vietnam (Ha Long

Sensory and skeletal development and growth in relation to the duration of the embryonic and larval stages in damselfishes (Pomacentridae)

Comparisons of rates of growth and development of larvae of four coral-reef damselfishes found a positive relationship between egg stage duration and developmental rate, and a negative correlation between larval stage durationand developmental rate.

Ontogeny and intervals of development in five reef-associated species of blenny from the northern Gulf of Mexico (Teleostei: Blenniidae)

Differences in fin and body pigmentation patterns and in the number of teeth between estuarine and coastal/shelf blennies suggest that development reflects adaptive convergence to similar ecological niches and habitats, rather than revealing any evolutionary relationship.

Characterizing natural intervals of development in the early life of fishes : an example using blennies ( Teleostei : Blenniidae )

We examined patterns and timing of ontogeny in five species of blenny (Teleostei: Blenniidae) from the northern Gulf of Mexico by assigning a suite of discrete character scores to individual

Larval and settlement periods of the northern searobin ( Prionotus carolinus ) and the striped searobin ( P. evolans )*

– This study reports new information about searobin ( Prionotus spp.) early life history from samples col­ lected with a Tucker trawl (for plank­ tonic stages) and a beam trawl (for newly settled



Metamorphosis of the visual and barbel sensory systems at settlement in the reef fish Upeneus tragula (Family Mullidae)

Sensory barbels, which aid in the detection and manipulation of prey items once settled, underwent rapid growth at settlement, largely due to the expansion of taste bud cells.

Description, interpretation and use of the microstructure of otoliths from juvenile butterflyfishes (family Chaetodontidae)

Each species demonstrated exponential growth in weight, but their patterns of growth in standard length differed, and Chaetodon rainfordi had exponentially decreasing growth in length up to the age of 300 d, whilst C. plebius grew linearly for at least 200 d.

Age estimation, based on unvalidated annual increments in otoliths indicated that fishes from the water tanks were all older than normal fishes of similar size, and suggests that the increase in relative eye size in tank fishes may have been the result of maintenance of ocular growth, in the face of reduced rates of somatic growth.

Effects of feeding history on the growth characteristics of a reef fish at settlement

The experiment suggests that U. tragula are physiologically well suited to exploiting a patchy food source, and that food availability within the pelagic stages can have a major influence on the growth characteristics of this reef fish at settlement.

The retinal structure of the goatfish Upeneus tragula was examined at various stages of the fish's development from pre-settlement pelagic larvae to benthic juveniles and visual acuity was found to increase rapidly prior to settlement to an asymptote of approximately 27 minutes of arc, which corresponded to settlement.

The influence of pelagic life history on the quality of tropical goatfish (family Mullidae) at settlement

This study examines how processes within the pelagic life stage influence the quality of newly settling reef fish and explores the ramifications of variable quality to the dynamics of reef fish populations.

Validation of a technique for reconstructing daily patterns in the recruitment of coral reef damselfish

The daily pattern of recruitment to a coral reef was successfully reconstructed using the otoliths from a large sample of juvenile fish collected at the end of the breeding season because the original pattern of settlement was preserved in the age distribution for at least 4 to 5 months.

Towards an explanation of the developmental strategy in leptocephalous larvae of marine teleost fishes

The observation that basic similarities are found in the developmental pattern of all groups of fishes with a leptocephalus (Superorder: Elopomorpha) forms the basis for proposing a common strategy within the superorder.


It cannot be assumed that newly-appeared fish on the reef settled that day and experiments are necessary to ascertain the meaning of marks on the otolith, to demonstrate that metamorphosis takes about five days.

Towards a Better Definition of "Metamorphosis" in Coregonus sp.: Biochemical, Histological, and Physiological Data

In Coregonus sp. the period between hatching and metamorphosis is characterized by an enhanced involvement of glycolysis in energy metabolism (as reflected by oxygen consumption and enzyme
