X-ray Diffraction Study of Acellular Teleost Bone

January 1961 · Nature

THE osseous endoskeletons of the higher orders of teleost fish are noteworthy in that they are totally devoid of enclosed osteocytes (Fig. 1)1,2. The osseous tissue of other fish, like that of all other vertebrates, contains enclosed osteocytes. Although acellular bone, per se, is phylogenetically a very ancient tissue3, its appearance as the sole osseous element in the skeletal systems of the ... [Show full abstract] most highly evolved and successful fish suggests that possession of such a tissue confers an adaptive value to the organism in a marine environment.

August 1971

Greg P. Busacker

The age and growth of largemouth bass was studied in a thermally loaded 4,500 acre-reservoir. Growth of fish from the Hotwater Arm was compared to that from a Control Arm. Maximum discharge temperature was 37C which elevated the Hotwater Arm 0.5-11.5C above the Control Arm. The reservoir was formed in 1966, clear for 3 years, but became turbid in '69-'70, the time of the study. Heated water had ... [Show full abstract] no effect on water quality. Checks formed on the scales in winter and summer which made age and growth analysis difficult. No differences were found between body-scale relationships or condition factors. Heated water had these measurable effects upon the bass: (1) Annulus formation occurred one month earlier; (2) it extended the growing season and annual increment of growth; (3) bass were attracted to heated water and provided an excellent winter fishery. Heated water had no apparent deleterious effects on largemouth bass.

Marine invertebrate immunodefense responses: Molecular and cellular approaches in tunicates

December 1996 · Annual Review of Fish Diseases

The reason for analyzing tunicate recognition systems is two-fold. First, they can be established as primitive models for understanding fundamental immunological mechanisms by analyzing either their individual cells in vivo or in vitro. Discovered mechanisms could provide alternatives to traditional mammalian (mouse, rat) and emerging models (fish, amphibians) in answering basic questions ... [Show full abstract] concerning immunity and disease. Moreover, their advantages lie in: (a) the simplicity of primitive systems (minimal hemopoietic sites), allowing a more effective dissection of variables; (b) their limited expense when compared to experimentation using vertebrates; and (c) their being socially non-controversial. Second, techniques of cell and molecular biology are equally applicable to tunicates as invertebrate models. Despite the considerable advances of recent years, many fundamental or conceptual aspects of immunological reactivity remain unresolved. A clear understanding of the system's evolutionary past will help to elucidate mechanisms which are complex and difficult to decipher in mammals, as we postulate, the immunorecognition systems of vertebrates evolved from simpler systems. Then tunicate immunodefense responses are excellent examples for analyses.

Living in the Mud with No Respect; Seasonal Distribution of the Pacific Hagfish (Eptatretus stouti)...

August 2014

Hagfish have a special place in the psyche of humans, ranging from utter disgust, to intrigue over their place in vertebrate evolution, and finally supporting lucrative fisheries; yet we know little about many species. The Pacific Hagfish supports lucrative fisheries throughout much of its range although limited life history data are available. Through a two year fishery independent sampling ... [Show full abstract] program off the central California coast, we examined the seasonal patterns of abundance and reproductive status of Pacific Hagfish in areas that had not previously been fished. We collected 9,807 hagfish at depths ranging between 64-550m and noted significant differences in distribution by sex and season. Although individuals of both sexes could be found throughout our study area, mature females were more commonly found in deeper waters (>91m) while mature males dominated inshore landings. Pacific Hagfish make directed migrations presumably for reproductive purposes with both sexes moving inshore for the winter/spring before females move offshore in the late spring to deposit eggs in the benthos. As traditional fisheries decline through restrictive management regimes, additional harvesters may look to enter the Pacific Hagfish fishery which underscores the need to collect baseline data to better inform management practices. -------------------------

Note on the terminal nerve in chimaeroid fishes (Holocephali, Chimaeridae)

December 2012 · Cybium: International Journal of Ichthyology

William Locy in 1905 on page 63 of his morphological and embryological account “On a newly recognized nerve connected to the fore-brain of selachians” mentions the “new nerve” or “supernumerary nerve” as it was termed before that time, tentatively traced upon dissection of the brain of Chimaera monstrosa. The terminal nerve as designated by Locy has never been mentioned for holocephalan fishes ... [Show full abstract] since, though new interest arose more recently with description of the terminal nerve in a variety of vertebrates ranging from cyclostomes to man. This study fills a gap in our anatomical knowledge and describes the nervus teminalis in juvenile spotted ratfish (Hydrolagus colliei) and rabbit fish (Chimaera monstrosa) on the basis of whole-stained and serially sectioned specimens.

The Hypothalamus–Pituitary System in Non-Mammalian Vertebrates

December 2013

The progressive evolution of hypothalamic centers in vertebrates is evident from examination of different vertebrates. The pattern of regulation has branched within the fishes, with the most recent fishes (teleosts) exhibiting predominantly neuroglandular control of tropic hormone release. Primitive fishes, including the chondrichthyeans, and tetrapods have specialized in neurovascular control ... [Show full abstract] with the development of a distinct median eminence and a hypophysial portal blood system. The distinct regionalization of tropic cell types in the fish adenohypophysis is less marked in tetrapods. The adenohypophysis of fishes is usually separable into a rostral pars distalis, a proximal pars distalis, and a pars intermedia. The pars tuberalis of tetrapods is absent in fishes but a unique ependymal structure is evident, the saccus vasculosus. Lungfishes lack both a pars tuberalis and the saccus vasculosus.

September 2014 · Proceedings of the Royal Society B

To understand how ecosystems are structured and stabilized, and to identify when communities are at risk of damage or collapse, we need to know how the abundances of the taxa in the entire assemblage vary over ecologically meaningful timescales. Here, we present an analysis of species temporal variability within a single large vertebrate community. Using an exceptionally complete 33-year monthly ... [Show full abstract] time series following the dynamics of 81 species of fishes, we show that the most abundant species are least variable in terms of temporal biomass, because they are under density-dependent (negative feedback) regulation. At the other extreme, a relatively large number of low abundance transient species exhibit the greatest population variability. The high stability of the consistently common high abundance species—a result of density-dependence—is reflected in the observation that they consistently represent over 98% of total fish biomass. This leads to steady ecosystem nutrient and energy flux irrespective of the changes in species number and abundance among the large number of low abundance transient species. While the density-dependence of the core species ensures stability under the existing environmental regime, the pool of transient species may support long-term stability by replacing core species should environmental conditions change.

Teleost as models for human vertebral stability and deformity

March 2007 · Comparative Biochemistry and Physiology Part C Toxicology & Pharmacology

Vertebral development is a dynamic and complicated process, and defects can be caused by a variety of influences. Spinal curvature with no known cause (idiopathic scoliosis) affects 2-3% of the human population. In order to understand the etiology and pathogenesis of complex human skeletal defects such as idiopathic scoliosis, multiple models must be used to study all of the factors affecting ... [Show full abstract] vertebral stability and deformity. Although fish and humans have many of the same types of offenses to vertebral integrity, they have been overlooked as a resource for study. The most common morphological deformity reported for fish are those that occur during the development of the spinal system, and as with humans, curvature is a common morphological consequence. Here we review spinal curvature in teleosts and suggest that they are an unexploited resource for understanding the basic elements of vertebral stability, deformity, development and genetics. Fish can be a value to vertebral research because they are tractable, have a diversity of non-induced vertebral deformities, and substantial genomic resources. Current animal models lack non-induced deformities and the experimental tractability necessary for genetic studies. The fact that fish are free of an appendicular skeleton should allow for analysis of basic spinal integrity without the biomechanical constraints observed in quadrupedal and bipedal models. To illustrate the point we review human idiopathic scoliosis and the potential contribution teleosts can make for the identification of causes, risk factors, and treatment options.
