Between November 1984 and April 1987, the butterflyfishes of One Tree Reef on the southern Great Barrier Reef were sampled on 8 occasions at 9 widely dispersed localities across the reef using a hierarchial sampling regime. Data were collected on 23 species which fell into 3 categories of abundance. Three 'abundant' species each contributed > 10 O/O of the total of all individuals. Five species were 'common', each contributing 2 to 10 "; o of the total, and 15 species were 'rare', each contributing < 1.0 % of the total. The 8 'abundant' and 'common' species were present at all localities, whilst 11 of the 'rare' species had restricted and discontinuous distributions. The former 8 demonstrated significant differences in abundance amongst localities, 5 of which also had significant differences amongst sites (within combinations of occasions and localities) Relationships between fish abundance and coral abundance were weak, and could not predict these spatial patterns. The size structures of the 3 abundant species inchcated consistent spatial differences, implying different population dynamics occurring on adjacent and local areas of reef. Five abundant and common species showed significant temporal variation, 2 species showed a seasonal pattern of variation, and 3 species showed increases in population density. Generally, however, spatial differences amongst localities were maintained through time.

“…In fact, hiding places and high-quality food seem to be common prerequisites for all small territorial herbivores (e.g. Low 1971, Ebersole 1977, Labelle and Nursall 1992, Letourneur 1992, Haley and Müller 2002, Medeiros et al 2010b, given the disadvantageous net costs of defending low-quality territories (see reviews by Dill 1978 andEbersole 1980). Randall (1996) reported that turf algae were the only preferred benthic item of O. trinitatis and filamentous algae were the primary food item of O. atlanticus.…”

Abundance and behavioural ecology of the blenny <em>Ophioblennius trinitatis</em> (Teleostei: Blenniidae) at an oceanic archipelago of Brazil (Atlantic)

Summary: Local patterns of fish density, microhabitat use, feeding behaviour, bite rate, territory area and agonistic interactions were recorded for Ophioblennius trinitatis at an oceanic archipelago (southwestern Atlantic). Rugosity, number of crevices and benthic diversity positively predicted the distribution of O. trinitatis. Turf algae was the preferred food item at all sites, but given its high availability inside and outside territory boundaries, it did not seem to be a limiting factor on the density of this blenny, as opposed to substrate heterogeneity. Bite rate was higher in the afternoon and for smaller individuals (juveniles). Territory size showed local variation and, although larger territories may be an effect of density-dependent conditions (more available space in low-density areas), we propose that individuals expand territories to compensate for residing in areas of lower quality (i.e. of low structural complexity). Larger individuals defended larger territories and residents responded differently to intruders, with higher rates of agonistic interactions towards potential competitors. Higher agonistic rates were also observed in larger territories and at low-complexity sites.Keywords: behaviour; Blennidae; Brazil; density; territory; microhabitat. La abundancia y la ecología del comportamiento del blenny Ophioblennius trinitatis (Teleostei: Blenniidae) en un archipiélago oceánico de Brasil (Atlántico) Resumen: En este trabajo se han estudiado las pautas en la densidad, la utilización del micro hábitat, el comportamiento alimentario, las tasas de mordisqueo, la superficie del territorio y las interacciones agonísticas de Ophioblennius trinitatis en un archipiélago oceánico del SO Atlántico. Los mejores predictores de la distribución de O. trinitatis fueron la rugosidad, el número de grietas y la diversidad bentónica. El turf algal es el alimento preferido de este pez en todos los lugares, pero dada su elevada disponibilidad, dentro y fuera de los territorios, no pareció ser un factor limitante para este blénido como lo fue la heterogeneidad del substrato. La tasa de mordisqueo resultó ser más elevada entre los peces pequeños (juveniles) y especialmente por la tarde. La superficie del territorio presentó notables variaciones locales y, a pesar de que los territorios mayores pueden ser el resultado de un efecto denso-dependiente (al haber más espacio disponible en la zonas con densidades bajas), proponemos que los individuos expanden su territorio para compensar la baja calidad ambiental de ciertas zonas (una baja complejidad estructural). Los ejemplares mayores defendían territorios más extensos y respondían de manera diferente ante los intrusos, con una mayor tasa de interacciones agonísticas hacia los potenciales intrusos. Las interacciones agonísticas también fueron más elevadas en los territorios más amplios y con una baja complejidad.Palabras clave: comportamiento; Blennidae; densidad; territorio; micro hábitat.

“…In the author's opinion, problems on complicated relations between territory and individual space seem to occur not only to the fishes that can shift their territory (Apogon notatus) or overrun their territorial boundary in pursuing intruders, such as Eupomacentrus planifrons (Myrberg et al, 1974), Plecoglossus altivelis (Mizuno et al, 1957) and Gerres oyena (in the spring season of 1976, unpublished data), but also to the fishes showing well defined territories such as Hypsypops rubicunda (Clarke, 1971), Gerres oyena (Usuki, 1976) and Pomacentrus jlavicauda (Low, 1971). Leyhausen (1971) suggested that in sedentary animals, the intolerance toward others expressed as individual distance may increase during the breeding season to the point that it becomes a territory.…”

Abstract(!) Underwater observations and experiments on pair formation in Apogon notatus were conducted almost every morning in June to July, 1976 in a rocky region north of the Seto Marine Biological Laboratory. (2) Experiments manifested that homing of this fish at least in the rocky region can be referred to the "pharotaxis". But homing in the sandy area remains still unexplained. (3) The usual sex recognition of this fish is thought to be based primarily on the differences in behavioural patterns between the sexes, while the mate identification in paired fish is supposed to be closely related to their determined attitude at the nest site. (4) Defended space, or individual space of paired fish is regarded as territory from the viewpoints of territory definition and its functional significance. (5) The smaller aggregations formed mostly in the season of pair formation is comparable with "the club" of the herring gull, Larus argentatus, from the viewpoint of animal sociology. As the aggregated fish maintain their restricted area for the time, the term "home site" may be used in explaining the behaviours of this fish. This seemingly accords with the results of studies on other fishes.
