  • Appendicularia of CTAW
    APPENDICULARIA APPENDICULARIA a b Fig. 26. Oikopleura albicans (Leuckart, 1854), a commonly occurring appendicularian species: a, dorsal view; b, lateral view. (Scale bar = 0.1 mm). [after T. Prentiss, reproduced with permission, from Alldredge 1976] Appendicularians are small free swimming planktonic tunicates, their bodies consisting of a short trunk and a tail (containing the notochord cells) which is present through the life of the individual. Glandular (oikoplast) epithelium on the trunk secretes the mucous house which encloses the whole or part of the body and contains the complex filters which strain food from the water driven through them (Deibel 1998; Flood & Deibel 1998). Unlike other tunicates, there is no peribranchial cavity and a pair of pharyngeal perforations (spiracles) surrounded by a ring of cilia open directly to the exterior from the floor of the pharynx. The early studies of these organisms, begun with Chamisso's description of Appendicularia flagellum Chamisso, 1821, were confounded by questions of its phylogenetic affinity. Chamisso classified his species with medusoids, Mertens (1830) with molluscs, and Quoy & Gaimard (1833) with zoophytes. Only in 1851 were appendicularians correctly assigned to the Tunicata by Huxley. At the time of this placement, the existence of more than one taxon was only just beginning to be recognised, and despite Huxley's work, they were not universally regarded as adult organisms—some authors still insisting that they were ascidian larvae or a free swimming generation of the sessile ascidians (Fenaux 1993). Subsequently, these questions were resolved by the work of Fol (1872) on material from the Straits of Messina, which forms the basis of later studies on the large collections of the great expeditions of the 19th century that revealed their true diversity in the oceanic plankton.

  • Seriola Dumerili (Greater Amberjack)
    UWI The Online Guide to the Animals of Trinidad and Tobago Diversity Seriola dumerili (Greater Amberjack) Family: Carangidae (Jacks and Pompanos) Order: Perciformes (Perch and Allied Fish) Class: Actinopterygii (Ray-finned Fish) Fig. 1. Greater amberjack, Seriola dumerili. [http://portal.ncdenr.org/web/mf/amberjack_greater downloaded 20 October 2016] TRAITS. The species Seriola dumerili displays rapid growth during development as a juvenile progressing to an adult. It is the largest species of the family of jacks. At adulthood, S. dumerili would typically weigh about 80kg and reach a length of 1.8-1.9m. Sexual maturity is achieved between the age of 3-5 years, and females may live longer and grow larger than males (FAO, 2016). S. dumurili are rapid-moving predators as shown by their body form (Fig. 1) (FLMNH, 2016). The adult is silvery-bluish in colour, whereas the juvenile is yellow-green. It has a characteristic goldish side line, as well as a dark band near the eye, as seen in Figs 1 and 2 (FAO, 2016; MarineBio, 2016; NCDEQ, 2016). DISTRIBUTION. S. dumerili is native to the waters of Trinidad and Tobago. Typically pelagic, found between depths of 10-360m, the species can be described as circumglobal. In other words, it is found worldwide, as seen in Fig. 3, though much more rarely in some areas, for example the eastern Pacific Ocean (IUCN, 2016). Due to this distribution, there is no threat to the population of the species, despite overfishing in certain locations. Migrations do occur, which are thought to be linked to reproductive cycles.

  • The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom
    lopmen ve ta e l B Williamson, Cell Dev Biol 2012, 1:1 D io & l l o l g DOI: 10.4172/2168-9296.1000101 e y C Cell & Developmental Biology ISSN: 2168-9296 Research Article Open Access The Origins of Chordate Larvae Donald I Williamson* Marine Biology, University of Liverpool, Liverpool L69 7ZB, United Kingdom Abstract The larval transfer hypothesis states that larvae originated as adults in other taxa and their genomes were transferred by hybridization. It contests the view that larvae and corresponding adults evolved from common ancestors. The present paper reviews the life histories of chordates, and it interprets them in terms of the larval transfer hypothesis. It is the first paper to apply the hypothesis to craniates. I claim that the larvae of tunicates were acquired from adult larvaceans, the larvae of lampreys from adult cephalochordates, the larvae of lungfishes from adult craniate tadpoles, and the larvae of ray-finned fishes from other ray-finned fishes in different families. The occurrence of larvae in some fishes and their absence in others is correlated with reproductive behavior. Adult amphibians evolved from adult fishes, but larval amphibians did not evolve from either adult or larval fishes. I submit that [1] early amphibians had no larvae and that several families of urodeles and one subfamily of anurans have retained direct development, [2] the tadpole larvae of anurans and urodeles were acquired separately from different Mesozoic adult tadpoles, and [3] the post-tadpole larvae of salamanders were acquired from adults of other urodeles. Reptiles, birds and mammals probably evolved from amphibians that never acquired larvae.

Snapper and grouper are important fishery resources with great commercial value for exporters to major international markets. The fisheries also support the livelihoods and food security of many local, small-scale fishing communities worldwide. It is therefore all the more critical that management of these fisheries improves, thus ensuring this important resource will remain available to provide both food and income. Landings of snapper and grouper have been steadily increasing: in the 1950s, total landings were about 50,000 tonnes, but they had grown to more than 612,000 tonnes by 2013.
