The equations = − fishery between total length (TL) and weight (W) were: log10 W 2.326 + = − management, 3.139 log10 TL for males and log10 W 2.366 + 3.168 log10 TL for fe- introduced males. There were highly significant differences between the sexes and species, for both sexes the value of b (slope of the log (TL-W regression) was Lake Trasimeno greater than 3 (3.139 for males and 3.168 for females), indicating positive allometric growth. The parameters of the theoretical growth curve were: −1 TLt = 10.03 cm; k = 0.18 yr , t0 = −0.443 yr and Φ = 1.65. Monthly trends of overall condition and the gonadosomatic index (GSI) indicated that the reproductive period occurred from March to September. Analy- sis of back-calculated lengths indicated the occurrence of a reverse Lee’s phenomenon. -

Research in Zoology 2014, 4(2): 29-42 DOI: 10.5923/j.zoology.20140402.01 Comparative Osteology of the Jaws in Representatives of the Eurypterygian Fishes Yazdan Keivany Department of Natural Resources (Fisheries Division), Isfahan University of Technology, Isfahan, 84156-83111, Iran Abstract The osteology of the jaws in representatives of 49 genera in 40 families of eurypterygian fishes, including: Aulopiformes, Myctophiformes, Lampridiformes, Polymixiiformes, Percopsiformes, Mugiliformes, Atheriniformes, Beloniformes, Cyprinodontiformes, Stephanoberyciformes, Beryciformes, Zeiformes, Gasterosteiformes, Synbranchiformes, Scorpaeniformes (including Dactylopteridae), and Perciformes (including Elassomatidae) were studied. Generally, in this group, the upper jaw consists of the premaxilla, maxilla, and supramaxilla. The lower jaw consists of the dentary, anguloarticular, retroarticular, and sesamoid articular. In higher taxa, the premaxilla bears ascending, articular, and postmaxillary processes. The maxilla usually bears a ventral and a dorsal articular process. The supramaxilla is present only in some taxa. The dentary is usually toothed and bears coronoid and posteroventral processes. The retroarticular is small and located at the posteroventral corner of the anguloarticular.

The study of the Portuguese marine ichthyofauna has a long historical tradition, rooted back in the 18th Century. Here we present an annotated checklist of the marine fishes from Portuguese waters, including the area encompassed by the proposed extension of the Portuguese continental shelf and the Economic Exclusive Zone (EEZ). The list is based on historical literature records and taxon occurrence data obtained from natural history collections, together with new revisions and occurrences. -
True Eels Or Freshwater Eels - Anguillidae
ISSN 0859-290X, Vol. 5, No. 1 – September 1999 [Supplement No. 6] Even if the eels, in the perception of most people, constitute a readily recognizable group of elongated and snakelike fish, the eels do not constitute a taxonomic group. There is considerable confusion related to eels. See the following system used in "Fishes of the Cambodian Mekong" by Walther Rainboth (1996). In the Mekong, two orders (Anguilliformes and Synbranchiformes) including five eel-Iike fish families are represented: The true eels (Anguillidae), the worm eels (Ophichthidae), the dwarf swamp eels (Chaudhuriidae), the swamp eels (Synbranchidae), and the spiny eels (Mastacembelidae). Of these, the swamp eels and spiny eels are by far the most important in the fisheries. True eels or Freshwater eels - Anguillidae The name "freshwater eels", is not a good name to describe the habits of the species in this family. All the anguillid species are catadromous (a catadromous fish is bom in the sea, but lives most of its life in fresh water). The sexually mature fish migrate down to the sea to spawn, and the juveniles ("the elvers") move, sometimes for a considerable distance, up the river to find their nursery areas. The true eels, contrary to most of the other Mekong eels, have two gill openings, which are high on each side of the fish. The body is covered with small scales that are deeply embedded in the skin. Pelvic fins are absent, while pectoral fins are well developed. The long dorsal and anal fins are continuous with the caudal fin, and the fins are not preceded by any spines. -

We discuss how critical 33 threshold changes in summer discharge can potentially tilt the Eel from a recovering salmon-supporting 34 ecosystem toward a cyanobacterially-degraded one. To maintain food webs and habitats that support 35 salmonids and suppress harmful cyanobacteria, summer discharge must be sufficient to connect mainstem 36 pools hydrologically with gently moving, cool base flow. Rearing salmon and steelhead can survive even 37 in pools that become isolated during summer low flows if hyporheic exchange is sufficient. -

For each individual, somatic morphology was described with 13 metrics and eight meristic measurements, while the otolith contour shape of 452 individuals from the three habitats was analysed using Fourier analysis. Then, two discriminant analyses, one using the 13 metric measurements and the other using Fourier descriptors, were used in order to discriminate populations of A. boyeri. The results of the discriminant analyses based on the two methods were similar, and showed that this species could be discriminated into three distinct groups: (1) marine punctuated, (2) lagoon and marine unpunctuated and (3) estuarine. These results are consolidated by the comparison of the Mayr, Linsley and Usinger coefficient of difference for the meristic parameters according to the location origin, where the difference reached a racial or even sub- specific level for some characters, depending on which pairs of populations were compared. -

The phylogeny is calibrated with six carefully chosen fossil taxa to pro- vide an explicit timeframe for the diversification of this group. Our results support the subdivision of Keywords: Atheriniformes into two suborders (Atherinopsoidei and Atherinoidei), the nesting of Notocheirinae Silverside fishes within Atherinopsidae, and the monophyly of tribe Menidiini, among others. We propose taxonomic Marine to freshwater transitions Marine dispersal changes for Atherinopsoidei, but a few weakly supported nodes in our phylogeny suggests that further Molecular markers study is necessary to support a revised taxonomy of Atherinoidei.
