Temperature tolerance and trophic dynamics were studied for three species (L. angustifrons, L. microlepis and L. mariae). Subsequently, several individuals of these three species were shipped to Heart of the Hills Research Station (HOHRS) in Ingram, Texas in 1975 (Rutledge and Lyons 1976 [cited by Schofield (2011) but not accessed for this report]). Also in 1975, Nile perch (L. niloticus) were transferred from Lake Turkana, Kenya, to HOHRS. All fishes were held in indoor, closed-circulating systems (Rutledge and Lyons 1976).” “From 1978 to 1985, Lates spp. was released into various Texas reservoirs (Howells and Garrett 1992 [cited by Schofield (2011) but not accessed for this report]). Almost 70,000 Lates spp. larvae were stocked into Victor Braunig (Bexar Co.), Coleto Creek (Goliad Co.) and Fairfield (Freestone Co.) reservoirs between 1978 and 1984.

[…] Asia: Turkey.” Status in the United States No information on occurrence, status, sale or trade in the United States was found. Chondrostoma nasus falls within Group I of New Mexico’s Department of Game and Fish Director’s Species Importation List (New Mexico Department of Game and Fish 2010). Group I species “are designated semi-domesticated animals and do not require an importation permit.” With the added restriction of “Not to be used as bait fish.” 1 Means of Introductions in the United States No introductions have been reported in the United States. Remarks Although the accepted and most used common name for Chondrostoma nasus is “Common Nase”, it appears that the simple name “Nase” is sometimes used to refer to C. nasus (Zbinden and Maier 1996; Jirsa et al. 2010).

    Annals of Parasitology 2015, 61(2), 85–92 Copyright© 2015 Polish Parasitological Society Original papers Species richness and diversity of the parasites of two predatory fish species – perch (Perca fluviatilis Linnaeus, 1758) and zander ( Sander lucioperca Linnaeus, 1758) from the Pomeranian Bay Iwona Bielat, Monika Legierko, Ewa Sobecka Division of Hydrobiology, Ichthyology and Biotechnology of Breeding, Faculty of Food Sciences and Fisheries, West Pomeranian University of Technology, Kazimierza Królewicza 4, 71-550 Szczecin, Poland Corresponding author: Ewa Sobecka; e-mail: [email protected] ABSTRACT. Pomeranian Bay as an ecotone is a transition zone between two different biocenoses, which is characterized by an increase in biodiversity and species density. Therefore, Pomeranian Bay is a destination of finding and reproductive migrations of fish from the rivers entered the area. The aim of the study was to compare parasitic fauna of two predatory fish species from the Pomeranian Bay, collected from the same fishing grounds at the same period. A total of 126 fish studied (53 perches and 73 zanders) were collected in the summer 2013. Parasitological examinations included: skin, fins, gills, vitreous humour and lens of the eye, mouth cavity, body cavity and internal organs. Apart from the prevalence and intensity of infection (mean, range) the parasite communities of both fish species were compared. European perch and zander were infected with parasites from five different taxonomic units. The most numerous parasites were Diplostomum spp. in European perch and Bucephalus polymorphus in zander. The prevalence of infection of European perch ranged from 5.7% ( Diphyllobothrium latum ) to 22.3% ( Diplostomum spp.) and for zander from 1.4% ( Ancyrocephalus paradoxus , Hysterothylacium aduncum ) to 12.3% ( Bucephalus polymorphus ).

  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

  • FOOD and FEEDING HABITS of BAY AD FISH BAGRUS BAJAD (FORSSKAL, 1775) in El-NOZHA HYDRODROME, ALEXANDRIA, EGYPT
    Egypt. J. Aquat. Bio!. & Fish.. Vol. 7, No.3: 197- 211 (2003) ISSN 1110- 6131 FOOD AND FEEDING HABITS OF BAY AD FISH BAGRUS BAJAD (FORSSKAL, 1775) IN El-NOZHA HYDRODROME, ALEXANDRIA, EGYPT Shnoudy A. Bakhoum and Samir. N. Faltas National Institute of Oceanography and Fisheries, Alexandria. Egypt Key words: Bagrus bajed, food, feeding habits, El-Nozha Hydrodrome ABSTRACT n order to elucidate the food and feeding habits of Bagrus bajed Ifish, stomach contents of 188 specimens with total body length ranging from 22 to 71cm were examined. Samples were collected monthly during the period from July 2000 to December 2001 from the commercial catch of El-Nozha Hydrodrome. The results of relative gut index indicated that B. bajed is carnivore. The range of its food material is wide, including cichiid species (Oreochromis niloticus, Oreochromis aureus, Sarotherodon galilaeus and Tilapia zillii), mullets ( Mugil cephalus and Liza ramada ), Clarias garlepinus, fish eggs, amphipods (Corophium volutator), shrimps ( Leander serratus) , aquatic insects (chironomid larvae and Coleoptera), vegetable matter and detritus. The maximum feeding intensity was in spring, while the lowest was in winter. Seasonal variation in the diet composition of B bajed revealed that fish prey was the main food item eaten throughout the year except in spring, where it represents the second important food item- after crustaceans. Variation in food species with fish length revealed an increase in the percentage of fish prey in the diet of this species. The diversity in diet of B. bajed, revealed low values in spring increasing in autumn and winter to reach the maximum in summer.
