Armed with this knowledge, it then becomes possible to predict potential range expansion and possible ecological effects of the exotic species. The purpose of this document is to review European literature on the round goby (Neogobius melanostomus) and provide a fairly comprehensive bibliography of goby literature, including annotations and abstracts. On the whole, we have not attempted to evaluate the material. Unfortunately, the quality of both the sources and the published translations varies, so errors may be present. Obvious typographical errors (e.g., misspellings) have been corrected in the reprinting of published abstracts; curiosities in syntax have not been changed to avoid inadvertent alteration of the meaning. This document was stimulated, in part, by the Round Goby Conference held in Chicago in February, 1996. We have included the abstracts from that conference, which present up-to-date research findings from North America, and a summary of a discussion of research priorities that was held on the second day of the conference. Additional materials and resources pertinent to the round goby are provided in appendices. A note on terminology: the terms 'goby' and 'gobies' refer to the round goby throughout the text, except in the section entitled "Biology of the Gobiidae" and in the annotated bibliography. Unless otherwise noted, all measurements of length are total length. Three terms were encountered in the European literature that deserve definition, but do not warrant a glossary: centner is 100 kg (used in commercial fisheries and fisheries assessment); girlo is a strait or arm of a large river flowing into inland sea; liman is an estuary. p. 7 Biology of Gobiidae Round gobies belong to the family Gobiidae, in the order Perciformes. Gobiidae is the second largest teleost family after Cyprinidae, and contains about 212 genera and approximately 1875 species (Nelson 1994). The Eleotridae (sleepers) are sometimes grouped under the family Gobiidae. Most of the species have fused pelvic fins that can form a suction disc with weak adhesion. The dorsal fin is spiny, with 2 to 8 flexible spines, and is separate from the soft dorsal fin. An external lateral line on the body is usually absent The scales can be cycloid or ctenoid and are occasionally absent. The largest goby species grows up to 50 cm, but the majority of species are less than 30 cm. The family includes the smallest vertebrate species, Trimmatom nanus, which grows to only 8-10 mm (Pandakapygmaea is also listed in this role, but grows to 11.5 mm). The family is distributed worldwide in both salt and freshwater habitats, but the majority of species are found in sub-tropical to tropical marine habitats. The family Gobiidae is characterized by species with tolerances for an extreme diversity of environmental conditions. Gillichthys miriabilis,for example, is highly tolerant of hypoxia and is one of the most widely euryhaline fish species. This species gulps air and conducts respiratory exchange within the buccopharynx (mouth and throat). Species such as the mudskippers (Boleophthalmus, Periophthalmus,and Periophthalmodon)are semi- terrestrial, and can spend several days out of water (Nelson 1994). Gobies also have diverse reproductive strategies, including simultaneous and sequential hermaphroditism, and abbreviate and protracted iteroparity. Elaborate courtships and male displays are common; the mudskipper, for example, uses its dorsal fin for signalling. Many species are sexually dimorphic. Males may be larger than females, and have a different coloration that becomes intensified during the spawning season. All species lay benthic eggs attached to the substrate, and males usually protect the

Since the work of J.J. Heckel (1846-1849), the number of valid species has increased significantly and the systematic status of many of the species has changed, and reorganization and updating of the published information has become essential. Here we take the opportunity to provide a new and updated checklist of freshwater fishes of Iran based on literature and taxon occurrence data obtained from natural history and new fish collections. This article lists 288 species in 107 genera, 28 families, 22 orders and 3 classes reported from different Iranian basins. However, presence of 23 reported species in Iranian waters needs confirmation by specimens.

Both sexes presented a paired reproductive tract with both sides active and asymmetric gonad development. Microscopic and macroscopic observations of the testes were consistent and indicated seasonality of spermatogenesis. The spermatocyst de - velopment pattern in mature individuals could not be assigned to any of the categories described in the literature. The ovaries−epigonal organ association was of the external type. Although all Squatinidae share a conservative morphology, they show differences across species in the func- tionality of the paired reproductive tract, seasonality of spermatogenesis, coiled spermatozoa and the presence of egg candles.

(†) Deceased SUMMARY: The southern Brazilian coast is the major fishery ground for the Brazilian sardine (Sardinella brasiliensis), a species responsible for up to 40% of marine fish catches in the region. Fish spawning and recruitment are locally influenced by seasonal advection of nutrient-rich waters from both inshore and offshore sources. Plankton communities are otherwise controlled by regenerative processes related to the oligotrophic nature of the Tropical Water from the Brazil Current. As recorded in other continental margins, zooplankton species diversity increases towards outer shelf and open ocean waters. Peaks of zooplankton biomass and ichthyoplankton abundance are frequent on the inner shelf, either at upwelling sites or off large estuarine systems. However, meandering features of the Brazil Current provide an additional mechanism of upward motion of the cold and nutrient-rich South Atlantic Central Water, increasing phyto- and zooplankton biomass and produc- tion on mid- and outer shelves. Cold neritic waters originating off Argentina, and subtropical waters from the Subtropical Convergence exert a strong seasonal influence on zooplankton and ichthyoplankton distribution towards more southern areas.

  • Spatial and Temporal Distribution of the Demersal Fish Fauna in a Baltic Archipelago As Estimated by SCUBA Census
    MARINE ECOLOGY - PROGRESS SERIES Vol. 23: 3143, 1985 Published April 25 Mar. Ecol. hog. Ser. 1 l Spatial and temporal distribution of the demersal fish fauna in a Baltic archipelago as estimated by SCUBA census B.-0. Jansson, G. Aneer & S. Nellbring Asko Laboratory, Institute of Marine Ecology, University of Stockholm, S-106 91 Stockholm, Sweden ABSTRACT: A quantitative investigation of the demersal fish fauna of a 160 km2 archipelago area in the northern Baltic proper was carried out by SCUBA census technique. Thirty-four stations covering seaweed areas, shallow soft bottoms with seagrass and pond weeds, and deeper, naked soft bottoms down to a depth of 21 m were visited at all seasons. The results are compared with those obtained by traditional gill-net fishing. The dominating species are the gobiids (particularly Pornatoschistus rninutus) which make up 75 % of the total fish fauna but only 8.4 % of the total biomass. Zoarces viviparus, Cottus gobio and Platichtys flesus are common elements, with P. flesus constituting more than half of the biomass. Low abundance of all species except Z. viviparus is found in March-April, gobies having a maximum in September-October and P. flesus in November. Spatially, P. rninutus shows the widest vertical range being about equally distributed between surface and 20 m depth. C. gobio aggregates in the upper 10 m. The Mytilus bottoms and the deeper soft bottoms are the most populated areas. The former is characterized by Gobius niger, Z. viviparus and Pholis gunnellus which use the shelter offered by the numerous boulders and stones. The latter is totally dominated by P.

Journal of the Ocean Science Foundation, 29, 32–54. doi: http://dx.doi.org/10.5281/zenodo.1115683 Introduction The gobiid genus Eviota, known as dwarfgobies, is a very speciose genus of teleost fishes, with 113 valid described species occurring throughout the Indo-Pacific Ocean (Table 1), and many more awaiting description. It is the fifth most speciose saltwater teleost genus, and second only to the 129 species in the eel genusGymnothorax in the coral-reef ecosystem (Eschmeyer et al. 2017). Information on the systematics and biology of the species of the genus is scattered in the literature, often in obscure references, and, other than the taxonomic key to all the species in the genus (Greenfield & Winterbottom 2016), no recent overview of the genus exists.

  • Comparison of an Active and a Passive Age-0 Fish Sampling Gear in a Tropical Reservoir
    Comparison of an Active and a Passive Age-0 Fish Sampling Gear in a Tropical Reservoir M. Clint Lloyd, Department of Wildlife, Fisheries and Aquaculture, Mississippi State University, Box 9690 Mississippi State, MS 39762 J. Wesley Neal, Department of Wildlife, Fisheries and Aquaculture, Mississippi State University, Box 9690 Mississippi State, MS 39762 Abstract: Age-0 fish sampling is an important tool for predicting recruitment success and year-class strength of cohorts in fish populations. In Puerto Rico, limited research has been conducted on age-0 fish sampling with no studies addressing reservoir systems. In this study, we compared the efficacy of passively-fished light traps and actively-fished push nets for sampling the limnetic age-0 fish community in a tropical reservoir. Diversity of catch between push nets and light traps were similar, although species composition of catches differed between gears (pseudo-F = 32.21, df =1,23, P < 0.001) and among seasons (pseudo-F = 4.29, df = 3,23, P < 0.006). Push-net catches were dominated by threadfin shad (Dorosoma petenense), comprising 94.2% of total catch. Conversely, light traps collected primarily channel catfish Ictalurus( punctatus; 76.8%), with threadfin shad comprising only 13.8% of the sample. Light-trap catches had less species diversity and evenness compared to push nets, consequently their efficiency may be limited to presence/ absence of species. These two gears sampled different components of the age-0 fish community and therefore, gear selection should be based on- re search goals, with push nets an ideal gear for threadfin shad age-0 fish sampling, and light traps more appropriate for community sampling.
