Two separate dorsal fins, the first with 6 or 7 short spines, depressible into a shallow groove on dorsal midline, followed by 1 spine and 19 to 21 soft rays; anal fin with 2 detached spines followed by 16 to 19 soft rays; posterior soft dorsal- and anal-fin rays consisting of semidetached finlets; bases of anal and second dorsal fins about equal in length; height of second dorsal-fin lobe 14.6 to 18.0% of fork length in specimens larger than 15 cm fork length; pelvic fins about equal in length or shorter than pectoral fins. Lateral line only slightly irregular, weakly to moderately convex above pectoral fin, becoming straight posteriorly. No scutes; scales on midbody below lateral line partially embedded and lanceolate. No caudal peduncle grooves. Vertebrae 10 + 16. Colour: in life, head and body greenish-grey dorsally, grey to silvery below; sides of adults with 4 to 8 vertically elongate plumbeous blotches, most of which intersect lateral line. Dorsal and anal fins dusky to dark and uniformly pigmented; pectoral fin yellow sand pelvic fin white in adults. DISTINGUISHING CHARACTERS OF SIMILAR SPECIES OCCURRING IN THE AREA: Scomberoides commersonnianus: upper jaw extends well beyond posterior margin of eye, especially in large adults; adults with inner and outer row teeth in lower jaw sub- equal in height (versus inner row teeth dis- tinctly longer than teeth in outer row); and spots on body, if present, large oval blotches. S. lysar: and S. tol: total gillrakers on first gill arch 21 to 27 (versus 11 to 15); lobe of dorsal fin abruptly dark on distal half (not uniformly pigmented); and dorsal fin lobe shor- ter, 7.7 to 11.2% of fork length in specimens larger than 15 cm fork length (versus 14.4 to 19.8%). S. commersonnianus S. tala Other species of Carangidae: upper lip not joined to snout at midline by a bridge of skin and posterior soft dorsal and anal fin rays not consisting of semidetached finlets; additionally many carangids differ in having at least the posterior straight part of the lateral line with scutes. S. commersonnianus S. tala teeth on lower jaw SIZE: Maximum: largest specimen examined 62 cm fork length. GEOGRAPHICAL DISTRIBUTION AND BEHAVIOUR: S. lysan In the Indian Ocean known only from Sri Lanka, where it is relatively common, but probably also occurs on the west coast of India. Elsewhere, known from the east coast of India, Andaman Islands, Gulf of Thailand, Malay- sia, Indonesia, the Philippines, Australia and the Solomon Islands. An inshore species whose biology is poorly known. S. tala Adults feed primarily on other fish. PRESENT FISHING GROUNDS: Coastal waters throughout its range. CATCHES, FISHING GEAR AND FORMS OF UTILIZATION: Separate statistics are not reported for this species. Caught with drift setnets, gilinets, seines and on hook and line. Marketed mostly fresh. As is true of all members of the genus, the spines of the first dorsal and anal fins are venomous (especially the latter) and capable of inflicting painful stings.

The South China Sea is a major water body containing a large and diverse fish fauna. However, many areas of the South China Sea, particularly in Malaysia and Vietnam, have been poorly studied in terms of fish taxonomy and diversity. Local fish scientists and students have frequently faced difficulty when try- ing to identify fishes in their home countries.

Samples were obtained monthly since January 2018 to February 2019 from the artisanal fishermen and the commercial fleet of Mar del Plata. A histological analysis was carried out and the main biologic-reproductive parameters were estimated: fecundity, oocyte frequency distribution and gonadosomatic index (GSI). Both the macroscopic and microscopic analyses showed reproductive activity in March and November. Mature females were recorded, which showed hydrated oocytes, as was evidenced by the histological procedures. Both, the histological and the oocyte diameter distribution analyses showed the presence of all oocyte Submitted December 11, 2019 maturation stages in ovaries in active-spawning subphase, indicating that Accepted July 9, 2020 P. signata is a multiple spawner with indeterminate annual fecundity.

A new species, Trachinotus macrospilus, is described from the Marquesas Islands where it is endemic and the only species of the genus present. It differs from the other spotted Indo-West Pacific species most noticeably in having adults with only one or two large spots on each side, the largest spot larger than the iris diameter, and in having no large spot positioned above the pectoral fin. An identification key is given for all Indo-West Pacific species of Trachinotus and a molecular phylogeny, including 16 of the 20 valid species of Trachinotus is presented.

In this study, 563 specimens (292 males, 247 females, and 24 of unknown sex) were collected from the north-west of the Persian Gulf from Oct. 2011 to Jan. 2013. Length-weight relationships and condition factor were determined for each sex in four length classes within different seasons. In general, the growth pattern in this fish was negatively allometric and the length-weight relationship in combined sexes amounted to W=2.9109FL-1.8424. The growth pattern of combined sexes was negatively allometric in spring and autumn and isometric in summer and winter. Also, growth pattern was positively allometric in 8-31 class, negatively allometric in the 31-54 cm and 54-77 cm classes and isometric in the 77-100 cm class among all specimens.

Fish samples were collected monthly by gillnet and trawls from the northern Arabian Sea coast of Pakistan from July 2013 to June 2014. The gonad maturity was categorized in six developmental stages based on visual analysis (colour, morphology) and histological screening of the gonads. The males of Talang queenfish dominated the population with a ratio of 1:0.4 (♂ to ♀) whereas females were higher (1:1.6) in needlescaled queenfish population. Talang queenfish was reproductively active during summer with a peak in June and winter spawning season, which appeared from November to February. Needlescaled queenfish is repeatedly spawner, appeared to be in spawning in the summer and fall. Estimated size-at-sexual- maturity for Talang and needlescaled queenfish suggests that the minimum legal length (MLL) should not be set lower than 35, 38 cm TL respectively. This conservative MLL, equal to or more than a length at functional maturity of both queenfish species would safeguard immature individuals until they reach a size at which they can contribute to Downloaded from jifro.ir at 8:27 +0330 on Thursday September 30th 2021 the reproductive capacity of the populations in the northern Arabian Sea coast.

THULASITHA and Kuganathan SIVASHANTHINI * Department of Zoology, Faculty of Science, University of Jaffna, Sri Lanka Thulasitha W.S., Sivashanthini K. 2013. Reproductive characteristics of doublespotted queenfish, Scomberoides lysan (Actinopterygii: Perciformes: Carangidae), from Sri Lankan waters: Implications for fisheries management. Acta Ichthyol. Piscat. 43 (1): 7–13. Background. The doublespotted queenfish, Scomberoides lysan (Forsskål, 1775), is one of the most important and highly priced food fishes popular for dry fish production in Sri Lanka. Knowledge of spawning pattern and season are important for the management of S. lysan. The biology of S. lysan is poorly known, however, and no specific management regime is available for this species in Sri Lanka. The presently reported study is the first attempt to understand the reproductive characteristics of S. lysan with implications for its management. Materials and methods. Weekly samples, totalling 1429 specimens, were collected from Sri Lankan marine waters from January 2010 to December 2011, analyzed macroscopically, and their maturity stages identified. Sex ratio, size at maturity, length-class distribution, monthly distribution of maturity stages, fecundity, and the indices related to reproduction were examined. Statistical analyses were performed to determine relations between gonad weight, total length, fork length, and fecundity. Results. Females were categorized macroscopically into five maturity stages, males into four (males mature slightly earlier than females). Spawning and spent stages of females were only available during June and September and significant peaks in the gonadosomatic index of males and females were also noted from these two months.
