OLNEY1 Department of Fisheries Science, School of Marine Science, Virginia Institute of Marine Science, Gloucester Point, Virginia 23062, USA “‘Must a name mean something?’ Alice asked doubtfully. ‘Of course it must,’ Humpty Dumpty said with a short laugh...” (Lewis Carroll, Through the Looking Glass, 1872) Abstract.—Fishes in the subfamily Alosinae (the shads, Family: Clupeidae) are properly termed alosine species, alosine clupeids, or alosines. The name “Alosidae” has never been formally presented as a family-level name that included the alosine genus Alosa and has no standing in fish classification. The term “alosid” is similarly meaningless since no fish family name “Alosidae” exists. Scientists, fishery managers, administrators, and the public should avoid these invalid names when referring to the shads.

  • The Freshwater Herring of Lake Tanganyika Are the Product of a Marine Invasion Into West Africa
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Open Marine Archive Marine Incursion: The Freshwater Herring of Lake Tanganyika Are the Product of a Marine Invasion into West Africa Anthony B. Wilson1,2¤*, Guy G. Teugels3, Axel Meyer1 1 Department of Biology, University of Konstanz, Konstanz, Germany, 2 Zoological Museum, University of Zurich, Zurich, Switzerland, 3 Ichthyology Laboratory, Royal Museum for Central Africa, Tervuren, Belgium Abstract The spectacular marine-like diversity of the endemic fauna of Lake Tanganyika, the oldest of the African Great Lakes, led early researchers to suggest that the lake must have once been connected to the ocean. Recent geophysical reconstructions clearly indicate that Lake Tanganyika formed by rifting in the African subcontinent and was never directly linked to the sea. Although the Lake has a high proportion of specialized endemics, the absence of close relatives outside Tanganyika has complicated phylogeographic reconstructions of the timing of lake colonization and intralacustrine diversification. The freshwater herring of Lake Tanganyika are members of a large group of pellonuline herring found in western and southern Africa, offering one of the best opportunities to trace the evolutionary history of members of Tanganyika’s biota. Molecular phylogenetic reconstructions indicate that herring colonized West Africa 25–50MYA, at the end of a major marine incursion in the region. Pellonuline herring subsequently experienced an evolutionary radiation in West Africa, spreading across the continent and reaching East Africa’s Lake Tanganyika during its early formation. While Lake Tanganyika has never been directly connected with the sea, the endemic freshwater herring of the lake are the descendents of an ancient marine incursion, a scenario which may also explain the origin of other Tanganyikan endemics.

  • ORIGINAL ARTICLES Length-Weight Relationship and Condition Factor
    49 Research Journal of Fisheries and Hydrobiology, 6(2): 49-53, 2011 ISSN 1816-9112 ORIGINAL ARTICLES Length-Weight Relationship and Condition Factor of Pontic Shad, Alosa immaculata (Pisces: Clupeidae) From the Southern Black Sea Savaş Yılmaz, Nazmi Polat Department of Biology, Faculty of Arts and Sciences, Ondokuz Mayıs University, 55139, Kurupelit, Samsun, Turkey ABSTRACT Seasonal variations in the length-weight relationship and condition factor of pontic shad, Alosa immaculata Bennett, 1835 collected from the Turkish Black Sea coast were investigated. A total of 730 individuals, 438 female and 292 male, were caught between December 2004 and October 2005. The length-weight relationships of females and males did not differ statistically in the same season. However, the length-weight relationships of sexes were seen to vary depending on the seasons. The parameter b of length-weight relationship was determined as 3.303 in females and 3.249 in males. The condition factor ranged from 0.550 to 1.064 for females, with a mean value of 0.794 and from 0.557 to 1.047 for males, with a mean value of 0.761. The highest condition factor in both sexes was obtained in spring. The average condition factor of female and male individuals >21 cm total length displayed an upward trend. Key words: Length-weight relationship, condition factor, pontic shad, Alosa immaculata, Black Sea Introductıon The length-weight relationship (LWR) in fish is significantly important in terms of fishery ecology and stock management. The LWRs allow determining the average weight of the fish in a certain class of length (Beyer, J.E., 1987), estimating the productivity and biomass of a fish population (Hossain, M.Y, 2006) determining the condition factor of fish (Bolger, T 1989) making a morphological comparison between species and populations (King, R.P., 1996; Goncalves, J.M.S, 1997).

Records dating back to the early nineteenth century indicate that fishermen could tell the difference between alewives and bluebacks, which look very similar; however, historically they have been harvested together with little regard to the differences between the two (Collette and Klein­MacPhee 2002). Alewives are the more common of the two species in most rivers in Maine (Collette and Klien­ MacPhee 2002). Fishermen in Maine often use the word “alewife” to refer to both alewives and bluebacks. Both alewives and bluebacks are anadromous fish, meaning that they are born in fresh water, but spend the majority of their adult lives at sea.

    Genetics and Molecular Biology Online Ahead of Print Copyright © 2009, Sociedade Brasileira de Genética. Printed in Brazil www.sbg.org.br High levels of genetic variability and differentiation in hilsa shad, Tenualosa ilisha (Clupeidae, Clupeiformes) populations revealed by PCR-RFLP analysis of the mitochondrial DNA D-loop region Sabuj Kanti Mazumder and Md. Samsul Alam Department of Fisheries Biology and Genetics, Bangladesh Agricultural University, Mymensingh, Bangladesh. Abstract The hilsa shad, Tenualosa ilisha (Clupeidae, Clupeiformes) is an important anadromous clupeid species from the Western division of the Indo-Pacific region. It constitutes the largest single fishable species in Bangladesh. Informa- tion on genetic variability and population structure is very important for both management and conservation pur- poses. Past reports on the population structure of T. ilisha involving morphometric, allozyme and RAPD analyses are contradictory. We examined genetic variability and divergence in two riverine (the Jamuna and the Meghna), two estuarine (Kuakata and Sundarbans) and one marine (Cox’s Bazar) populations of T. ilisha by applying PCR-RFLP analysis of the mtDNA D-loop region. The amplified PCR products were restricted with four restriction enzymes namely, XbaI, EcoRI, EcoRV, and HaeIII. High levels of haplotype and gene diversity within and significant differenti- ations among, populations of T. ilisha were observed in this study. Significant FST values indicated differentiation among the river, estuary and marine populations. The UPGMA dendrogram based on genetic distance resulted in two major clusters, although, these were subsequently divided into three, corresponding to the riverine, estuarine and marine populations. The study underlines the usefulness of RFLP of mtDNA D-loop region as molecular mark- ers, and detected at least two differentiated populations of T.

    BULLETIN OF MARINE SCIENCE, 41(3): 822-834, ]987 LARVAL KING MACKEREL (SCOMBEROMORUS CAVALLA), SPANISH MACKEREL (8. MACULATUS), AND BLUEFISH (POMATOMUS SALTATRIX) OFF THE SOUTHEAST COAST OF THE UNITED STATES, 1973-1980 Mark R. Collins and Bruce W Stender ABSTRACT Surface and subsurface ichthyoplankton collections were made from 9 m to beyond the continental shelf(deepest station 3,940 m) in all seasons from Cape Hatteras, North Carolina to Cape Canaveral, Florida. King mackerel spawn from April to at least September, primarily at depths >40 m. Spring spawning activity takes place further offshore than does summer spawning. An apparent concentration of larvae between 32° and 33°N suggests that the area of upwelling associated with the Charleston bump is an important spawning and/or nursery area. Spanish mackerel spawn from May to September in depths <40 m. Larvae were less abundant than those of king mackerel, and no areas of concentration were found. Vertical migration to the surface at night is indicated for both king and Spanish mackerels. Bluefish spawn bimodally from March through at least November in depths >40 m, with the primary spawning peak in spring and the secondary peak in late summer. In spring, larvae were caught most often between 32° and 33°N, but in summer-fall were taken more often at locations further south. Neither vertical migration or visually-cued net avoidance is indicated, but bluefish >4 mm are strongly associated with the surface. Spanish (Scomberomorus maculatus) and king (S. cavalla) mackerels and blue- fish (Pomatomus saltatrix) support large recreational and commercial fisheries along the east coast of the United States.
