WFB 232 Ichthyology Albuliformes (Latin albulus, “whitish”) Taxonomy: Superclass Gnathostomata - jawed fishes Class Actinopterygii Division Teleostei Order Albuliformes - bonefishes Families Albulidae 2 genera, 5 species Description: The two genera in this order are Albula (bonefishes) and Pterothrissidae (deep-sea bonefish). Spiny eels and halosaurs were formerly classified as part of this order, but are now categorized as their own separate order, Notacanthiformes. jawed and bony ray-finned fishes that have abdominal pelvic fins and low-based pectoral fins, along with forked caudal fins “mandibular sensory canal lying in an open groove in the dentary and angular bones” (FishBase). inferior mouth Habitat: Mostly marine, but occasionally found in freshwater and brackish environments. Distribution: Tropical and subtropical seas worldwide, especially in the Caribbean. Ecology and life history: Generally consume benthic invertebrates. Able to function in oxygen-poor environments using a lung-like air bladder. In regards to reproductive guild, they are categorized as nonguarders. As members of the superorder Elopomorpha, they share a distinctive larval stage called a “leptocephalus”. Additional details: First fossil evidence occurred in the late Cretaceous period. They are considered a highly significant game species despite being mostly inedible. A pair of bonefish swimming together are featured on the Bahamas’ 10-cent coin.

BONY FISHES 602 Bony Fishes
click for previous page BONY FISHES 602 Bony Fishes GENERAL REMARKS by K.E. Carpenter, Old Dominion University, Virginia, USA ony fishes constitute the bulk, by far, of both the diversity and total landings of marine organisms encoun- Btered in fisheries of the Western Central Atlantic.They are found in all macrofaunal marine and estuarine habitats and exhibit a lavish array of adaptations to these environments. This extreme diversity of form and taxa presents an exceptional challenge for identification. There are 30 orders and 269 families of bony fishes presented in this guide, representing all families known from the area. Each order and family presents a unique suite of taxonomic problems and relevant characters. The purpose of this preliminary section on technical terms and guide to orders and families is to serve as an introduction and initial identification guide to this taxonomic diversity. It should also serve as a general reference for those features most commonly used in identification of bony fishes throughout the remaining volumes. However, I cannot begin to introduce the many facets of fish biology relevant to understanding the diversity of fishes in a few pages. For this, the reader is directed to one of the several general texts on fish biology such as the ones by Bond (1996), Moyle and Cech (1996), and Helfman et al.(1997) listed below. A general introduction to the fisheries of bony fishes in this region is given in the introduction to these volumes. Taxonomic details relevant to a specific family are explained under each of the appropriate family sections. The classification of bony fishes continues to transform as our knowledge of their evolutionary relationships improves.

This type of tail primitively results from an ontogenetic fusion of centra (bodies of vertebrae) and the possession of paired bracing bones located bilaterally along the dorsal region of the caudal skeleton, derived ontogenetically from the neural arches (uroneurals) of the ural (tail) centra.

In extreme cases, when fishing pressure is high, aggregations can dwindle and even cease to form, sometimes within just a few years. Whether or not they will recover and what the long-term effects on the fish population(s) might be of such declines are not yet known. We do know, however, that healthy aggregations tend to be associated with healthy fisheries. It is, therefore, important to understand and better protect this critical part of the life cycle of aggregating species to ensure that they continue to yield food and support livelihoods. Why a Handbook? As fishing technology improved in the second half of the twentieth century, engines came to replace sails and oars, the cash economy developed rapidly, and human populations and demand for seafood grew, the pressures on reef fishes for food, and especially for money, increased enormously.

The Need for Sustainable Management of Coral Reef Fish Spawning Aggregations
Secretariat of the Pacific Community Seventh Heads of Fisheries Meeting (28 Feb.–4 March 2011, Noumea, New Caledonia) Working Paper 7 Original: English The need for sustainable management of coral reef fish spawning aggregations Yvonne Sadovy PhD The University of Hong-Kong and Eric Clua Coral Reef Initiative for the South Pacific (CRISP), SPC www.spc.int/fame/ SPC/HOF7/Working Paper 7 Page 1 The need for sustainable management of coral reef fish spawning aggregations 1. Many commercially important species of reef fishes exhibit the habit of ‘aggregation-spawning’ whereby all mating takes place in large temporary gatherings of conspecifics. Sometimes fish also migrate in large numbers to spawning sites. These mating-related gatherings and movements are often highly predictable in time and location and hence, once discovered, are often the basis of important seasonal fisheries. Yet, as we have come to discover over the last two decades, such reproductive gatherings are highly vulnerable to over-fishing and, if severely compromised by fishing, may cease to form completely. If this happens adults will no longer produce the eggs and larvae that form the basis of fisheries at non-reproductive times of the year, and the fishery is likely to collapse. Collapse would represent the loss of significant fisheries with important and sometimes serious implications for the human communities that depend on such fishes. Moreover, aggregations can represent significant biomass and movements of animals, and are formed by many species, highlighting the ecosystem importance of these biological events. 2. Species that predictably aggregate to spawn, or gather in large spawning migrations, include a diverse range of fishes of much importance as food and commercial benefit in the Pacific.

Betanodavirus and VER Disease: a 30-Year Research Review
pathogens Review Betanodavirus and VER Disease: A 30-year Research Review Isabel Bandín * and Sandra Souto Departamento de Microbioloxía e Parasitoloxía-Instituto de Acuicultura, Universidade de Santiago de Compostela, 15782 Santiago de Compostela, Spain; [email protected] * Correspondence: [email protected] Received: 20 December 2019; Accepted: 4 February 2020; Published: 9 February 2020 Abstract: The outbreaks of viral encephalopathy and retinopathy (VER), caused by nervous necrosis virus (NNV), represent one of the main infectious threats for marine aquaculture worldwide. Since the first description of the disease at the end of the 1980s, a considerable amount of research has gone into understanding the mechanisms involved in fish infection, developing reliable diagnostic methods, and control measures, and several comprehensive reviews have been published to date. This review focuses on host–virus interaction and epidemiological aspects, comprising viral distribution and transmission as well as the continuously increasing host range (177 susceptible marine species and epizootic outbreaks reported in 62 of them), with special emphasis on genotypes and the effect of global warming on NNV infection, but also including the latest findings in the NNV life cycle and virulence as well as diagnostic methods and VER disease control. Keywords: nervous necrosis virus (NNV); viral encephalopathy and retinopathy (VER); virus–host interaction; epizootiology; diagnostics; control 1. Introduction Nervous necrosis virus (NNV) is the causative agent of viral encephalopathy and retinopathy (VER), otherwise known as viral nervous necrosis (VNN). The disease was first described at the end of the 1980s in Australia and in the Caribbean [1–3], and has since caused a great deal of mortalities and serious economic losses in a variety of reared marine fish species, but also in freshwater species worldwide.

06_250317 part1-3.qxd 12/13/05 7:32 PM Page 15 Phylum Chordata Chordates are placed in the superphylum Deuterostomia. The possible rela- tionships of the chordates and deuterostomes to other metazoans are dis- cussed in Halanych (2004). He restricts the taxon of deuterostomes to the chordates and their proposed immediate sister group, a taxon comprising the hemichordates, echinoderms, and the wormlike Xenoturbella. The phylum Chordata has been used by most recent workers to encompass members of the subphyla Urochordata (tunicates or sea-squirts), Cephalochordata (lancelets), and Craniata (fishes, amphibians, reptiles, birds, and mammals). The Cephalochordata and Craniata form a mono- phyletic group (e.g., Cameron et al., 2000; Halanych, 2004). Much disagree- ment exists concerning the interrelationships and classification of the Chordata, and the inclusion of the urochordates as sister to the cephalochor- dates and craniates is not as broadly held as the sister-group relationship of cephalochordates and craniates (Halanych, 2004). Many excitingCOPYRIGHTED fossil finds in recent years MATERIAL reveal what the first fishes may have looked like, and these finds push the fossil record of fishes back into the early Cambrian, far further back than previously known. There is still much difference of opinion on the phylogenetic position of these new Cambrian species, and many new discoveries and changes in early fish systematics may be expected over the next decade. As noted by Halanych (2004), D.-G. (D.) Shu and collaborators have discovered fossil ascidians (e.g., Cheungkongella), cephalochordate-like yunnanozoans (Haikouella and Yunnanozoon), and jaw- less craniates (Myllokunmingia, and its junior synonym Haikouichthys) over the 15 06_250317 part1-3.qxd 12/13/05 7:32 PM Page 16 16 Fishes of the World last few years that push the origins of these three major taxa at least into the Lower Cambrian (approximately 530–540 million years ago).

E-mail: [email protected] Abstract This paper describes Elops smithi, n. sp., and designates a lectotype for E. saurus. These two species can be separated from the five other species of Elops by a combination of vertebrae and gillraker counts. Morphologically, they can be distinguished from each other only by myomere (larvae) or vertebrae (adults) counts. Elops smithi has 73–80 centra (total number of vertebrae), usually with 75–78 centra; E. saurus has 79–87 centra, usually with 81–85 centra. No other morphological character is known to separate E. smithi and E. saurus, but the sequence divergence in mtDNA cytochrome b (d = 0.023–0.029) between E. smithi and E. saurus is similar to or greater than that measured between recognized species of Elops in different ocean basins. Both species occur in the western Atlantic Ocean, principally allopatrically but with areas of sympatry, probably via larval dispersal of E.
