We examined health, prevalence and infection intensity of 2 microparasites, coccidia and epitheliocystis-like organisms (ELO), in L. kasmira from their introduced and native range including the islands where translocated fish originated (Tahiti and Marquesas Islands, French Polynesia) and from several other islands (American Samoa, Fiji and New Caledonia). In addition, we did a longitu- dinal survey of these parasites in the introduced range. Coccidia and ELO were widely distributed and were found on all islands except for New Caledonia. Health indices, as measured by overall organ lesions, body condition and parasite intensity, indicated that fish from Samoa were the least healthy, and fish from Midway (Hawaiian Archipelago) were the healthiest. Microparasite diversity was highest on Midway and Hawaii and lowest on New Caledonia.

Zoological Studies 51(8): 1490-1506. This study reports on (1) variations in the number and position of scleral ossicles in 283 actinopterygian species representing 172 families, (2) the distribution of the morphological variants of these bony elements, (3) the phylogenetic significance of these variations, and (4) a phylogenetic hypothesis relevant to the position of the Callionymoidei, Dactylopteridae, and Syngnathoidei based on these osteological variations. The results suggest that the Callionymoidei (not including the Gobiesocidae), Dactylopteridae, and Syngnathoidei are closely related. This conclusion was based on the apomorphic character state of having only the anterior scleral ossicle. Having only the anterior scleral ossicle should have evolved independently in the Syngnathioidei + Dactylopteridae + Callionymoidei, Gobioidei + Apogonidae, and Pleuronectiformes among the actinopterygians studied in this paper. http://zoolstud.sinica.edu.tw/Journals/51.8/1490.pdf Key words: Scleral ossicle, Actinopterygii, Phylogeny.

Randall, B.P.Bishop Museum, Hawaii, USA iagnostic characters: Small to medium-sized fishes (to 40 cm) with a moderately elongate, slightly com- Dpressed body; ventral side of head and body nearly flat. Eye near dorsal profile of head. Mouth relatively small, ventral on head, and protrusible, the upper jaw slightly protruding; teeth conical, small to very small. Chin with a pair of long sensory barbels that can be folded into a median groove on throat. Two well separated dorsal fins, the first with 7 or 8 spines, the second with 1 spine and 8 soft rays. Anal fin with 1 spine and 7 soft rays.Caudal fin forked.Paired fins of moderate size, the pectorals with 13 to 17 rays;pelvic fins with 1 spine and 5 soft rays, their origin below the pectorals. Scales large and slightly ctenoid (rough to touch); a single continuous lateral line. Colour: variable; whitish to red, with spots or stripes. 1st dorsal fin with 7or8spines 2nd dorsal fin with 1 spine and 8 soft rays pair of long sensory barbels Habitat, biology, and fisheries: Goatfishes are bottom-dwelling fishes usually found on sand or mud sub- strata, but 2 of the 4 western Atlantic species occur on coral reefs where sand is prevalent. The barbels are supplied with chemosensory organs and are used to detect prey by skimming over the substratum or by thrust- ing them into the sediment. Food consists of a wide variety of invertebrates, mostly those that live beneath the surface of the sand or mud.

  • Description of a New Species of Mullid Fish from South-Western Australia, with Comments on Upeneichthys Lineatus
    Description of a new species of mullid fish from south-western Australia, with comments on Upeneichthys lineatus J. Barry Hutchins* Abstract Ul'et1elch/lns .\Iu/li IS described from 30 SpCClnlCnS from south-western Australia (Albany to Shark Hay). It IS distinguished from U. linca/us. the only other member of lpeneich/hl.\. bv the different colour pattcrn on the snout (horizontal blue lines vcrsus obl14ue blue lines respectively). different fin sizes. and a much smaller maximum length (IJX mm SI. versus at least 2XO mm SI.). Evidence IS also provided to show that three distinct lorms of Ul'eneich/hl.\ linea/us can be recognised. 1'. linea/us linea/us from eastern Australia. 1'. linea/us \'/a/llingii from southern and south-western Australia. and 1'. linea/lIS l'urusllS from New Zealand. Introduction Fishes of the mullid genus Upcncichthrs inhabit sandy and silty bottoms in coastal waters of southern Australia and New Zealand. A recent revicw of the genus (Ben-Tuvia 1986) recognised only one species, U. linca/us (Bloch and Schneider, 180 I), but also included a comment concerning the considerable morphological variability of the taxon. Subsequently Hutchins and Swainston (1986) and Stewart (1987) both distinguished two species, U. linca/us and U. vlamingii (Cuvier, 1829), although the findings of each study differed considerably. Hutchins and Swainston used U. linca/us for an eastern Australian goatfish and U. vlamingii for a species inhabiting southern and south-western Australia. However, the unpublished study of Stewart recommended that the species characterised by a dark stripe along the side of the body be known as U.

  • Feeding Habits of the Striped Red Mullet, Mullus Surmuletus in the Eastern Adriatic Sea
    ISSN: 0001-5113 ACTA ADRIAT., ORIGINAL SCIENTIFIC PAPER AADRAY 59 (1): 123 - 136, 2018 Feeding habits of the striped red mullet, Mullus surmuletus in the eastern Adriatic Sea Mišo PAVIČIĆ, Jasna ŠILJIĆ, Dajana BRAJČIĆ JURICA and Sanja MATIĆ-SKOKO* Institute of Oceanography and Fisheries, Šetalište Ivana Meštrovića 63, P.O. Box. 500, 21000 Split, Croatia *Corresponding author: [email protected] Feeding habits of the striped red mullet, Mullus surmutetus in the eastern Adriatic Sea were investigated. Stomach contents of 203 specimens (11.5 - 32.9 cm TL) collected by bottom trawling were analyzed. Commonly accepted procedures were followed during the diet composition inspec- tion and standard keys were used for food items determination. Examinations showed that 39 iden- tified prey taxa belong to 11 major systematic groups: Crustacea, Gastropoda, Bivalvia, Pisces, Cnidaria, Echinodermata, Polychaeta, Nematoda, Bryozoa, Algae and Rhizaria. The predominant and preferred prey category was decapod crustaceans within all size categories and only in the largest individuals, the dominance of Bivalvia followed by Polychaeta and Crustacea were found. The largest individuals also showed more variety in consumption of different prey categories and a higher mean number of prey items in comparison with smaller fish. No significant differences in prey foraging between males and females (p>0.05) and regarding to season (p>0.05) were found. Feeding on such wide spectra of prey without significant variations regarding to sex and season suggests that the striped red mullets are able to adapt to shifts in spatio-temporal variations in the abundance of potential prey. Presence of detritus in the digestive tracts is highly related to its forag- ing behaviour on muddy detritic bottoms.
