Biology ( anglais )

fourni par Fishbase
A solitary species (Ref. 26340) occurring in coral reefs and rocky areas. It is considered an ambush predator that hides among the coral and sponges and is easy to approach. Frequents cleaning stations (Ref. 9710). The size versus sex distribution of Bermuda population indicates that this species is a protogynous hermaphrodite; all fish less than 37 cm TL were females and all fish larger than 45 cm TL were males (Ref. 6886). Randall (Ref. 33) reported food of 59 specimens 15 to 57 cm SL were purely fishes of a variety of species.

Tiger grouper ( anglais )

fourni par wikipedia EN

The tiger grouper (Mycteroperca tigris) is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the warmer waters of the western Atlantic Ocean.

Description

The tiger grouper has a body which is elongate, robust and compressed, its depth being the no greater at the origin of the dorsal fin as it is at the origin of the anal fin,[3] and a large mouth.[4] The standard length is 3.1 to 3.6 times the depth of the body. The preopercle is rounded and does not have a lobe at its angle.[5] The dorsal fin contains 11 spines and 15-17 soft rays while the anal fin contains 3 spines and 11 soft rays.[2] The membranes between the dorsal fin spines are obviously notched.[5] The caudal fin is a straight in juveniles and slightly concave in adults.[3] The upper body is dark and there are 9 to 11 thin, pale oblique lines. It is capable of dramatic changes in colour, as well as lightening or darkening its colour. It can even sometimes be bright red in colour, particularly when being attended to by cleaner fish. The juveniles are yellow with a dusky line along the flanks.[4] This species attains a total length of 101 centimetres (40 in), although they are commonly around 40 centimetres (16 in), and a maximum published weight of 10 kilograms (22 lb).[2]

Distribution

The tiger grouper is found in the western Atlantic Ocean from southeastern Florida, Bermuda and the Bahamas, as well as the Flower Garden Banks in the north, southwards through the Caribbean Sea to the Maroni River in French Guiana. A disjunct population occurs in Brazil where they are found from Ceara State to Rio de Janeiro State.[1]

Habitat and biology

The tiger grouper is a solitary species which is found on coral reefs and in rocky areas. It is an ambush predator of smaller fishes. It hides among coral and sponges and is attempts to remain concealed, even when approached. It attaneds the cleaning stations of cleaner fish. The population around Bermuda has a size distribution and sex ratio which suggest that tiger groupers are protogynous hermaphrodites, all of the fish with a total length less than 37 centimetres (15 in) were female and all of the fish with a total length greater than 45 centimetres (18 in) were male.[2] They are found at depths of 3 to 112 metres (9.8 to 367.5 ft). It is known to form spawning aggregations in the northern part of its range but these have not been recorded off Brazil.[1]

Taxonomy

The tiger grouper was first formally described as Serranus tigris in 1833 by the French zoologist Achille Valenciennes (1794-1865) with the type locality given as San Domingo.[6]

Utilisation

The tiger grouper is targeted by fisheries throughout its range. It is caught using handlines and by spear fishing.[1]

Mycteroperca tigris ( espagnol ; castillan )

fourni par wikipedia ES

La cuna gata o mero tigre (Mycteroperca tigris) es una especie de pez serránido americano propio de zonas arrecifales.

Descripción

Profundidad corporal de 3.1-3.6 veces y longitud de cabeza de 2.5-2.8 veces la longitud estándar. Fosas nasales posteriores de 3-5 veces más grandes que las frontales. Dientes grandes con caninos bien desarrollados. Preopérculo sin lóbulo sobresaliente en la esquina. El primer arco branquial posee 8 branquias incluyendo 5-6 rudimentarias en la extremidad superior, y en la extremidad inferior posee 15-17 branquias incluyendo 7-9 rudimentarias en la extremidad inferior. La aleta dorsal posee 11 espinas y 15-17 radios blandos, las membranas interespinales indentadas, aleta anal con tres espinas y 11 radios suaves, aleta anal blanda con radios medios alargados en adultos; aleta caudal redondeada en juveniles, truncada en peces de 60-80cm; 17 radios en la aleta pectoral. Escamas ctenoideas en la parte medio lateral del cuerpo en juveniles y lisas en adultos; 82-83 escamas en la línea lateral; 120 escamas laterales. Son de color azul-verdoso hasta marrón con abundantes manchas pequeñas marrones o naranjas; los espacios intermedios forman una red de color verde pálido o blanquesino; la cabeza y el cuerpo son más obscuros dorsalmente con nueve a 11 rayas pálidas oblicuas alternadas y más barras amplias oscuras; aletas con manchas y rayas pálidas irregulares; aletas pectorales de color amarillo pálido; el interior de la boca es naranja rojizo o naranja oscuro. Los juveniles (tres a diez centímetros de longitud estándar) son de colo amarillo con la franja medio lateral marrón negruzco desde la punta de la mandíbula inferior a través del ojo y a lo largo del cuerpo hasta la aleta caudal; éstas rayas no se juntan en la mandíbula inferior y al crecer se vuelven más tenues, e inician a oscurecerse las barras dorsales a partir de los 20 cm de longitud estándar. En los juveniles el patrón de barras dorsales oblicuas es un patrón causado por estrés. Su tamaño máximo es de 100 cm y un peso de 10 kg.[1]

Ecología

Habita en el Golfo de México desde el sur de Texas a la península de Yucatán, Las Bermudas, Florida, las Antillas, Venezuela hasta el sur de Brasil en arrecifes de coral y fondos rocosos entre los 10 y 40 metros de profundidad. Es un depredador de emboscada que se alimenta principalmente de peces.[1][2]

Reproducción

Al igual que las demás especies de serránidos es un hermafrodíta protogíneo; todos los peces de menos de 37 cm son hembras y los mayores de 45 cm son machos. Los machos en época de apareamiento muestran la cabeza de color amarillo pálido a bronce, aletas pectorales negras con puntas amarillas base de la aleta anal blanca; las hembras exhiben los colores habituales. Forman congregaciones reproductivas, y hembras y machos se desplazan juntos desde el fondo hasta media agua para liberar los huevos y el esperma en la corriente; las hembras pueden liberar entre 154,030 y 986,271 ovocitos. El desove ocurre después de cada luna nueva entre enero y abril. Alcanzan la madurez sexual a los dos años, o lo que es igual a los 25 cm de longitud estándar; un pez de 42 cm de longitud estándar puede tener 9 años.[1][2]

Conservación

Debido a su amplia zona de distribución es probable que su población no corra gran riesgo, sin embargo, se han notado disminuciones de esta especie en las islas antillanas y no existen datos de desembarco de esta especie en su área de distribución, lo que hace difícil saber el estado de explotación de la misma. Las capturas de estos peces durante sus congregaciones reproductoras generaría consecuencias negativas en su población.[2]
