  • Bony Fish Guide
    This guide will help you to complete the Bony Fish Observation Worksheet. Bony Fish Guide Fish (n.) An ectothermic (cold-blooded) vertebrate (with a backbone) aquatic (lives in water) animal that moves with the help of fins (limbs with no fingers or toes) and breathes with gills. This definition might seem very broad, and that is because fish are one of the most diverse groups of animals on the planet—there are a lot of fish in the sea (not to mention rivers, lakes and ponds). In fact, scientists count at least 32,000 species of fish—more than any other type of vertebrate. Fish are split into three broad classes: Jawless Fish Cartilaginous Fish Bony Fish (hagfish, lampreys, etc.) (sharks, rays, skates, etc.) (all other fish) This guide will focus on the Bony Fish. There are at least 28,000 species of bony fish, and they are found in almost every naturally occurring body of water on the planet. Bony fish range in size: • Largest: ocean sunfish (Mola mola), 11 feet, over 5,000 pounds • Smallest: dwarf pygmy goby (Pandaka pygmaea), ½ inch, a fraction of an ounce (This image is life size.) The following guide will help you learn more about the bony fish you can find throughout the New England Aquarium. Much of the guide is keyed to the Giant Ocean Tank, but can be applied to many kinds of fish. Even if you know nothing about fish, you can quickly learn a few things: The shape of a fish’s body, the position of its mouth and the shape of its tail can give you many clues as to its behavior and adaptations.

Roberts, DVM *, Stephen A. Smith, DVM, PhD KEYWORDS Pet fish Ornamental fish Branchitis Gill Wet mount cytology Hypoxia Respiratory disorders Pathology Living in an aquatic environment where oxygen is in less supply and harder to extract than in a terrestrial one, fish have developed a respiratory system that is much more efficient than terrestrial vertebrates. The gills of fish are a unique organ system and serve several functions including respiration, osmoregulation, excretion of nitroge- nous wastes, and acid-base regulation.1 The gills are the primary site of oxygen exchange in fish and are in intimate contact with the aquatic environment. In most cases, the separation between the water and the tissues of the fish is only a few cell layers thick. Gills are a common target for assault by infectious and noninfectious disease processes.2 Nonlethal diagnostic biopsy of the gills can identify pathologic changes, provide samples for bacterial culture/identification/sensitivity testing, aid in fungal element identification, provide samples for viral testing, and provide parasitic organisms for identification.3–6 This diagnostic test is so important that it should be included as part of every diagnostic workup performed on a fish.

  • Lecture 8 – Head and Jaw Osteology
    Lecture 8 – Head and Jaw osteology More derived fishes (Ray finned fishes) The variability of the jaw structure of bony fishes provides an explanation for the extensive adaptive radiation in the group and why they are so diverse and occupy almost every aquatic niche available. Skull diversity (A) carp, Cyprinus carpio, (B) vampire characin, Hydrolycus scomberoides, (C) catfish Arius felis. (D) cod Gadus morhua. (E) large-mouth bass, Micropterus salmoides (F) The parrotfish Scarus guacamaia. Scale bar = 10 mm WESTNEAT 2004 From an evolutionary standpoint, fishes were the first animals to develop bony jaws. Versatile jaws and multiple feeding strategies allowed fishes to fill, or radiate into, a diverse range of niches. They have evolved to feed in all possible ways – sucking, biting, scraping, nipping, crushing etc. The head of a teleost has 5 main regions: Cranium, jaws, cheeks, hydroid arch, opercula. The head of a fish has five main regions • 1) The CRANIUM is composed of the bones providing direct support and protection to the brain and the visual, Anterior Posterior olfactory, and auditory organs. Below the cranium is the parashenoid bone. • Parasphenoid plays a role in the jaws as Features of the neurocranium sensu lato (from Caranx it acts as a hard melampygus, lateral aspect, left, and posterior aspect, right).

  • Percomorph Phylogeny: a Survey of Acanthomorphs and a New Proposal
    BULLETIN OF MARINE SCIENCE, 52(1): 554-626, 1993 PERCOMORPH PHYLOGENY: A SURVEY OF ACANTHOMORPHS AND A NEW PROPOSAL G. David Johnson and Colin Patterson ABSTRACT The interrelationships of acanthomorph fishes are reviewed. We recognize seven mono- phyletic terminal taxa among acanthomorphs: Lampridiformes, Polymixiiformes, Paracan- thopterygii, Stephanoberyciformes, Beryciformes, Zeiformes, and a new taxon named Smeg- mamorpha. The Percomorpha, as currently constituted, are polyphyletic, and the Perciformes are probably paraphyletic. The smegmamorphs comprise five subgroups: Synbranchiformes (Synbranchoidei and Mastacembeloidei), Mugilomorpha (Mugiloidei), Elassomatidae (Elas- soma), Gasterosteiformes, and Atherinomorpha. Monophyly of Lampridiformes is justified elsewhere; we have found no new characters to substantiate the monophyly of Polymixi- iformes (which is not in doubt) or Paracanthopterygii. Stephanoberyciformes uniquely share a modification of the extrascapular, and Beryciformes a modification of the anterior part of the supraorbital and infraorbital sensory canals, here named Jakubowski's organ. Our Zei- formes excludes the Caproidae, and characters are proposed to justify the monophyly of the group in that restricted sense. The Smegmamorpha are thought to be monophyletic principally because of the configuration of the first vertebra and its intermuscular bone. Within the Smegmamorpha, the Atherinomorpha and Mugilomorpha are shown to be monophyletic elsewhere. Our Gasterosteiformes includes the syngnathoids and the Pegasiformes

  • Anatomy and Go Fish! Background
    Anatomy and Go Fish! Background Introduction It is important to properly identify fi sh for many reasons: to follow the rules and regulations, for protection against sharp teeth or protruding spines, for the safety of the fi sh, and for consumption or eating purposes. When identifying fi sh, scientists and anglers use specifi c vocabulary to describe external or outside body parts. These body parts are common to most fi sh. The difference in the body parts is what helps distinguish one fi sh from another, while their similarities are used to classify them into groups. There are approximately 29,000 fi sh species in the world. In order to identify each type of fi sh, scientists have grouped them according to their outside body parts, specifi cally the number and location of fi ns, and body shape. Classifi cation Using a system of classifi cation, scientists arrange all organisms into groups based on their similarities. The fi rst system of classifi cation was proposed in 1753 by Carolus Linnaeus. Linnaeus believed that each organism should have a binomial name, genus and species, with species being the smallest organization unit of life. Using Linnaeus’ system as a guide, scientists created a hierarchical system known as taxonomic classifi cation, in which organisms are classifi ed into groups based on their similarities. This hierarchical system moves from largest and most general to smallest and most specifi c: kingdom, phylum, class, order, family, genus, and species. {See Figure 1. Taxonomic Classifi cation Pyramid}. For example, fi sh belong to the kingdom Animalia, the phylum Chordata, and from there are grouped more specifi cally into several classes, orders, families, and thousands of genus and species.

Fisheries Occasional Publications No. 80, September 2010. ISSN: 1447 - 2058 ISBN: 1 921258 90 X Information about this guide he intention of the North Coast Fish Identification Guide is to provide a simple, Teasy to use manual to assist commercial, recreational, charter and customary fishers to identify the most commonly caught marine finfish species in the North Coast Bioregion. This guide is not intended to be a comprehensive taxonomic fish ID guide for all species. It is anticipated that this guide will assist fishers in providing a more comprehensive species level description of their catch and hence assist scientists and managers in understanding any variation in the species composition of catches over both spatial and temporal scales. Fish taxonomy is a dynamic and evolving field. Advances in molecular analytical techniques are resolving many of the relationships and inter-relationships among species, genera and families of fishes. In this guide, we have used and adopted the latest taxonomic nomenclature. Any changes to fish taxonomy will be updated and revised in subsequent editions. The North Coast Bioregion extends from the Ashburton River near Onslow to the Northern Territory border. Within this region there is a diverse range of habitats from mangrove creeks, rivers, offshore islands, coral reef systems to continental shelf and slope waters.

Use scissors to cut anteriorly through into the anus (also called the vent) of the fish. The anus is located the bones attached to the pelvic fins. Cut forward along the just anterior to (in front of) the anal fin, on the ventral (lower) side narrow, fleshy space beneath the head and between the gill of the fish in most fishes. covers. The gill covers (also known as operculae) are flaps which lie along both sides of the head and protect the underlying gills. 2. Cutting anteriorly. The incision is then extended anteriorly along the fish's belly towards the head. 5. Body cavity. Pull apart the two walls of the body cavity and expose the internal organs (see next image for names). The neat incision now runs from the anus forward between the two pelvic fins and along the isthmus. 3. Cut between pelvic fins . The incision passes anteriorly between the pelvic (ventral) fins. Depending on the type of fish, these paired fins are used to stabilise the fish when swimming and also for braking. The pelvic fins are supported by the bones of the . Some of the ventrally located internal pelvic girdle which are anchored in the belly muscles. 6. Internal organs organs: 1 heart, 2 Liver, 3 Pyloric caecae, 4 adipose (fatty) tissue 7.
