Diagnostic Description ( 英語 )

由Fishbase提供
This species is distinguished by the following characters: body compressed, moderately slender, its depth 2.3-2.8 in SL; last anal-fin spine 1.2-1.5 times in longest anal-fin spine (usually the third); soft parts of dorsal and anal fins low, longest dorsal-fin ray 0.7-1 times in longest dorsal-fin spine; caudal fin almost emarginate in specimens under 10 cm standard length, forked in larger fish; 16-26 (rarely 27) scale rows between lateral line and bases of leading dorsal-fin spines. Colour of body highly variable, greenish grey to yellow brown with numerous (100-200) pearly blue to whitish spots on nape and trunk, match-head size on lower sides; 2-3 rows between first spine of dorsal fin and lateral line (area of eye would cover about 6 spots in this region), and about 10 rows between highest point of lateral line and base of first anal-fin spine; when frightened or injured, sides mottled light and dark brown and cream, creating 6 or 7 regularly spaced, dark diagonal zones with paler zones of similar width between them; dark eye-sized spot usually just behind upper end of gill opening, and a narrow bar along upper edge of gill cover (Ref. 9813, 90102).Description: Closely resembles S. fuscescens but differs by its slightly more pointed snout and longer pectoral fins (1.1-1.3 in HL vs. 1.4-1.5 in S. fuscescens) (Ref. 1602). Color pattern is similar to that of S. argenteus and S. fuscescens.

Biology ( 英語 )

由Fishbase提供
Adults inhabit inshore, algae reefs, estuaries and in large lagoons with algae-rubble habitats. Mainly common on rocky substrates (Ref. 48637). In contrast to S. fuscescens, this species seems to tolerate more turbid waters, occurring within the vicinity of river mouths especially around seagrass beds. Adults also occur several kilometers offshore in deep, clear waters. Juveniles form very large schools in shallow bays and coral reef flats; school size reduces with size, with adults occurring in groups of 20 individuals or so. Herbivorous, feed on benthic algae and to some extent on seagrass. Fished by trawling and seine netting; bycatch in traps set in deep water and marketed fresh in very large numbers (Ref. 9813). Consumed as food; and have poisonous spines (Ref. 4537).

Siganus canaliculatus ( 英語 )

由wikipedia EN提供

Siganus canaliculatus, the white-spotted spinefoot, white-spotted rabbitfish, pearly spinefoot, seagrass rabbitfish, slimy spinefoot or smudgespot spinefoot is a species of marine ray-finned fish, a rabbitfish belonging to the family Siganidae. It is native to the western Pacific Ocean and Indian Ocean where it occurs on reefs and in lagoons.

Taxonomy

Siganus canaliculatus was first formally described in 1797 as Chaetodon canaliculatus by the Scottish explorer Mungo Park with the type locality given as Bengkulu Province on Sumatra.[4] This taxon is largely sympatric with the mottled spinefoot (Siganus fuscescens) and these taxa are also very similar in appearance. Molecular analyses in 2011 found that there were three separate lineages within S. canaliculatus and S. fuscescens, that these lineages interbred and that each lineage had specimens which referred to either taxon, this suggests that S. canaliculatus is a junior synonym of S. fuscescens.[5] This is not the position taken by FishBase[6] or Catalog of Fishes.[4] The specific name canaliculatus means “grooved”, a reference to the grooves in the fin spines. Park did not know that, like all rabbitfishes, these spines contained venom glands for defence.[7]

Description

Siganus canaliculatus has a moderately slender, laterally compressed body, the standard length being 2.3 to 2.8 times its depth. The dorsal profile of the head is weakly to notably concave over the eyes with a pointed snout. The front nostril has a flap, in juveniles this covers the rear nostril, although it becomes shorter as the fish grows and is completely absent in the oldest fishes.[8] The dorsal fin has 13 spines and 10 soft rays while the anal fin has 7 spines and 9 soft rays.[3] The front spine on the dorsal fin points forwards. The caudal fin is nearly emarginate in smaller individuals of less than 10 cm (3.9 in) standard length becoming forked in larger fish.[8] This species attains a maximum total length of 40 cm (16 in), although 20 cm (7.9 in) is more typical.[3]

The colour and pattern of the white-spotted spinefoot is very variable. It can be greenish grey to yellow brown and is marked with 100-200 perlescent blue to whitish spots on the nape and anterior part of the body, these are similar in size to a match-head on the lower flanks. There are 2 to 3 rows between the first spine of the dorsal fin and the lateral line, which are roughly one sixth the size of the eye, and another 10 or so rows between the uppermost point of the lateral line and the base of the first spine in the anal fin. Alarmed or injured fishes adopt a pattern where their flanks are mottled with patches of light and dark brown and cream, forming a pattern of 6 or 7 uniformly spaced, dark oblique zones with lighter zones of similar breadth separating them. There is normally dark spot immediately to the rear of the upper end of gill opening, this spot is similar in size to the eye, and a thin bar along the upper margin of the operculum.[8]

Distribution and habitat

Siganus canaliculatus has a wide Indo-Pacific distribution, ranging from the Persian Gulf to the Philippines and New Guinea, north to the Ryukyu Islands and south to northern Australia.[1] It is found at depths down to 50 m (160 ft)[1] with adults living in inshore waters, on algae reefs, in estuaries and in large lagoons where there is algae growing over rubble. The juveniles live in coral reef flats and shallow bays.[3]

Biology

Siganus canaliculatus is said to be able to tolerate more turbid waters than the closely related S. fuscescens and may be found near river mouths, particularly where there are beds of sea grass. The adults can sometimes be found quite far offshore, in clear, deep waters. The juveniles form very large schools, which reduce in size as the fishes mature; adults occur in groups of around 20 individuals.[3] When spawning, the adults gather in much larger aggregations.[8] These fishes have only been observed to spawn from April to July. However, gonadosomatic indices suggest that there is another, less defined spawning period in November. Spawning events are synchronised with the lunar cycle. A mature female can spawn a number of times in a season, laying up to a million eggs.[1] This is a herbivorous species which feeds on benthic algae and, to a lesser extent, on sea grass.[3] This species, like other siganids, has venom glands located in grooves on the spines of the dorsal and anal fins.[7]

Fisheries

Siganus canaliculatus is an important quarry species for commercial fisheries. In the Persian Gulf it is considered to be a good quality food fish, even though it is a rather small species. It is caught using bottom trawls and seine nets in coastal waters wherever it occurs. In the Persian Gulf, this species is caught largely by trapping in fences made up of nets in the inter-tidal zone and dome-shaped metal traps called gargoors. The fish landed are sold fresh in large numbers. This species is also taken as bycatch. The white-spotted spinefoot has been used for mariculture in some areas in which it occurs because it has herbivorous habits, grows rapidly and is economically valuable. In some parts of this species' range the stock has been overfished.[1]

Siganus canaliculatus, 95 mm, India

Siganus canaliculatus es una especie de peces marinos de la familia Siganidae, orden Perciformes, suborden Acanthuroidei.

Su nombre común es sigano pintado, y el más común en inglés es Whitespotted rabbitfish,[2]​ o pez conejo moteado de blanco.

Morfología

El cuerpo de los Siganidos es medianamente alto, muy comprimido lateralmente. Visto de perfil recuerda una elipse. La boca es terminal, muy pequeña, con mandíbulas no protráctiles.

La coloración base de la cabeza, el cuerpo y las aletas, es gris plateado. Tanto la cabeza como el cuerpo están decorados con un moteado de puntos blancos espaciados. La parte superior de la cabeza, la nuca y la espalda tienen una mancha verde oliva a amarillenta. Cuando se camufla utiliza un patrón de puntos y manchas marrones y crema pálido.

Cuentan con 13 espinas y 10 radios blandos dorsales, precedidos por una espina corta saliente, a veces ligeramente sobresaliente, y otras totalmente oculta. La aleta anal cuenta con 7 fuertes espinas y 9 radios blandos. Las aletas pélvicas tienen 2 espinas, con 3 radios blandos entre ellas, característica única y distintiva de esta familia. Las espinas de las aletas tienen dos huecos laterales que contienen glándulas venenosas.[3]

El tamaño máximo de longitud es de 30 cm,[4]​ aunque el tamaño medio de adulto es de 20 cm.[5]

Es muy parecido a S. fuscescens, pero se diferencia de él por tener el hocico más puntiagudo y la aletas pectorales más grandes.[6]​ El patrón de coloración es similar al de S. fuscescens o S. argenteus.

Reproducción

Alcanzan la madurez con 17 o 18 cm de longitud.[7]​ Son ovíparos y de fertilización externa. Los huevos son esféricos, transparentes y adhesivos.[8]​ El desove se produce al oscurecer, en los meses calurosos, coincidiendo con el ciclo lunar. Es un desovador múltiple, pudiendo los ejemplares mayores desovar más de una vez en la misma sesión de desove.[9]

Poseen un estado larval planctónico, y desarrollan un estado post-larval, característico del suborden Acanthuroidei, llamado acronurus, en el que los individuos son transparentes, y se mantienen en estado pelágico durante un periodo extendido antes de establecerse en el hábitat definitivo, y adoptar entonces la forma y color de juveniles, para evolucionar a la de adultos.

Alimentación

Son principalmente herbívoros. Progresan de alimentarse de fitoplancton y zooplancton, como larvas, a alimentarse de macroalgas, pastos marinos y pequeños invertebrados.[3]​ Consumen algas de los géneros Enhalus, Enteromorpha, Eucheuma, Gracilaria o de la especie Hypnea spinella, así como pequeños crustáceos e invertebrados como Balanus amphitrite, Bugula neritina, gusanos poliquetos como Hydroides elegans, ofiuras como Ophiura kinbergii, o isópodos como Limnoria tripunctata.[10]

Hábitat y comportamiento

Habitan en aguas tropicales, asociados a arrecifes de coral, en grandes lagunas ricas en escombros con algas, arrecifes interiores y estuarios.[11]​ También ocurren a varios kilómetros de la costa, en aguas claras y profundas. En contraste con S. fuscescens, soporta mejor aguas turbias en desembocaduras de ríos.

Los juveniles ocurren en escuelas muy grandes, en bahías soleadas, sobre camas de pastos marinos y corales. Según aumentan de tamaño, disminuye el número de individuos en los cardumenes, agrupándose los adultos en escuelas de unos 20 individuos.

Son diurnos, y por la noche duermen en grietas, desarrollando una coloración específica de camuflaje, en tonos pardos, y apagando sus vivos colores, en un ejercicio de cripsis, que también desarrollan cuando están estresados.

Su rango de profundidad es entre 3 y 50 metros.[5]

Son oceanódromos, lo que implica que realizan migraciones de más de 100 km, para desplazarse a las zonas de desove o alimentación, siendo estas migraciones periódicas y predecibles.[12]

Distribución geográfica

Estos peces se encuentran en el océano Pacífico oeste y en el Índico. Desde el golfo Pérsico hasta Nueva Caledonia.

Está presente en Andamán, Arabia Saudí, Australia, Baréin, Birmania, Camboya, Chagos, China, Corea del Sur, Emiratos Árabes Unidos, Filipinas, Hong Kong, India, Indonesia, Irak, Japón, Kuwait, Malasia, Omán, Nueva Caledonia, Palaos, Papúa Nueva Guinea, islas Ryukyu, Singapur, Sri Lanka, Tailandia, Taiwán, Vietnam y Yemen.[13]
