Reef Fish Species

Abstract The corallivorous Crown-of-Thorns Starfish (CoTS, Acanthaster spp.) has been linked with the widespread loss of scleractinian coral cover on Indo-Pacific reefs during periodic population outbreaks. Here, we re-examine CoTS consumption by coral reef fish species by using new DNA technologies to detect Pacific Crown-of-Thorns Starfish (Acanthaster cf. solaris) in fish faecal and gut content samples. CoTS DNA was detected in samples from 18 different coral reef fish species collected on reefs at various stages of CoTS outbreaks in the Great Barrier Reef Marine Park, nine of which had not been previously reported to feed on CoTS. A comprehensive set of negative and positive control samples confirmed that our collection, processing and analysis procedures were robust, although food web transfer of CoTS DNA cannot be ruled out for some fish species. Our results, combined with the (i) presence of CoTS spines in some samples, (ii) reported predation on CoTS gametes, larvae and settled individuals, and (iii) known diet information for fish species examined, strongly indicate that direct fish predation on CoTS may well be more common than is currently appreciated. We provide recommendations for specific management approaches to enhance predation on CoTS by coral reef fishes, and to support the mitigation of CoTS outbreaks and reverse declines in hard coral cover.

In the present study we record several instances of reef fish species foraging on epibionts of sea turtles (cleaning symbiosis) at the oceanic islands of Fernando de Noronha Archipelago and near a shipwreck, both off the coast of Pernambuco State, northeast Brazil. Nine reef fish species and three turtle species involved in cleaning are herein recorded. Besides our records, a summary of the literature on this association type is presented. Postures adopted by turtles during the interaction are related to the habits of associated fishes. Feeding associations between fishes and turtles seem a localized, albeit common, phenomenon.

A comprehensive research effort was directed to increase the ecological role of Putus-Putus island coral reefs. This study was an implementation of artificial reef technology as fish colonization locality. The artificial reefs were made of 20x20x100 cm-concrete blocks placed in 6 levels and located at the depth of 8-10 m. Reef fish observations were done three times in two locations. Environmental parameters, such as temperature, salinity and visibility, were also measured. Environmental parameters (temperature, salinity a. Water temperature (29.65oC and 29.64oC) supported the coral growth as well. Salinity distribution was not significantly different among the study sites. This study also found 37 reef fish species belonging to 18 families. Number of species varied with observed time and localities. Total number of individuals increased with number of fish species. Mean number of individuals and species of reef fish in locality B were higher than those in locality A. Moreover, the reef fish colonization rate in the study site followed the model y = 4.3801e0.5249x with R2= 0.9297 in the strait and y = 5.0397e0.5493x with R2= 0.9297 for the Bay.

ABSTRACTThere are some marine sanctuaries (DPL) which are managed together by its societies in North Minahasa regency. From 19 villages with DPL, we conducted surveys using point intercept transect in 14 villages both inside and outside DPL in the subdistrict West Likupang and East Likupang, North Minahasa. Result showed that live coral cover was in general in moderate to excellent conditions both inside and outside DPL. Reef fish recorded in the study areas consisted of 267 reef fish species which categorized into 40 families. Bahoi village had the highest abundance and biomass within the DPL due to a very good condition of coral reef ecosystemn (>75% coral cover) both inside and outside DPL. Biomass of reef fish outside DPL of Bahoi was small but its abundance was the highest. This conditions indicated that the size of reef fish outside of Bahoi DPL was small and this gave a positive perspective to supply fishes into the outside region of Bahoi DPL. Overall, marine sanctuary in North Minahasa contained reef fish community structure in good condition, moderate diversity, relatively labile of evenness index, and low dominance. Grouping by similarity, reef fish species were generally similar in all locations. The separation of DPL locations produced some different fishes group due to its different location, oceanographic conditions, and characters.

Reef Fish Species

Endemic species are frequently assumed to have lower genetic diversity than species with large distributions, even if closely related. This assumption is based on research from the terrestrial environment and theoretical evolutionary modelling. We test this assumption in the marine environment by analysing the mitochondrial genetic diversity of 33 coral reef fish species from five families sampled from Pacific Ocean archipelagos. Surprisingly, haplotype and nucleotide diversity did not differ significantly between endemic and widespread species. The probable explanation is that the effective population size of some widespread fishes locally is similar to that of many of the endemics. Connectivity across parts of the distribution of the widespread species is probably low, so widespread species can operate like endemics at the extreme or isolated parts of their range. Mitochondrial genetic diversity of many endemic reef fish species may not either limit range size or be a source of vulnerability.

Biological Attributes

AbstractGlobal biodiversity declines and increasing rates of extinction necessitate the assessment and prediction of the vulnerability of species to extinction. Here, we examine the relationships between conservation status and ecological traits of reef fish species of the Brazilian biogeographical province. We used binomial tests and a logistic regression to address two questions. Do biological attributes differ between threatened and non-threatened fishes? Which combination of traits and impacts exerts greater influence on species threat status? Of the 559 species, 36 are categorized as threatened (compiled from global, national and local Red Lists). Three species are categorized as Critically Endangered, seven as Endangered and 26 as Vulnerable. Our analyses revealed that Elasmobranchii, sex-changing bony fishes and endemic species are the most vulnerable reef fishes in Brazilian waters. Body size and trophic category were identified as good predictors of the vulnerability of a species to extinction. Small-bodied species that are exploited by the ornamental trade and have complex reproductive strategies are also of concern. Such combinations of attributes could be of value in predicting which reef fish species elsewhere have a high risk of extinction.

Abstract Somatic growth is a critical biological trait for organismal, population, and ecosystem-level processes. Due to its direct link with energetic demands, growth also represents an important parameter to estimate energy and nutrient fluxes. For marine fishes, growth rate information is most frequently derived from sagittal otoliths, and most of the available data stems from studies on temperate species that are targeted by commercial fisheries. Although the analysis of otoliths is a powerful tool to estimate individual growth, the time-consuming nature of otolith processing is one barrier for collection of comprehensive datasets across multiple species. This is especially true for coral reef fishes, which are extremely diverse. Here, we provide back-calculated size-at-age estimates (including measures of uncertainty) based on sagittal otoliths from 710 individuals belonging to 45 coral reef fish species from French Polynesia. In addition, we provide Von Bertalanffy growth parameters which are useful to predict community level biomass production.

Mass Mortalities

Reef fishes are a treasured part of marine biodiversity, and also provide needed protein for many millions of people. Although most reef fishes might survive projected increases in ocean temperatures, corals are less tolerant. A few fish species strictly depend on corals for food and shelter, suggesting that coral extinctions could lead to some secondary fish extinctions. However, secondary extinctions could extend far beyond those few coral-dependent species. Furthermore, it is yet unknown how such fish declines might vary around the world. Current coral mass mortalities led us to ask how fish communities would respond to coral loss within and across oceans. We mapped 6964 coral-reef-fish species and 119 coral genera, and then regressed reef-fish species richness against coral generic richness at the 1° scale (after controlling for biogeographic factors that drive species diversification). Consistent with small-scale studies, statistical extrapolations suggested that local fish richness across the globe would be around half its current value in a hypothetical world without coral, leading to more areas with low or intermediate fish species richness and fewer fish diversity hotspots.
