M. van den Boogaart Osse, J. W. M., and van den Boogaart, J. G. M. 1995. Fish larvae, development, allometric growth, and the aquatic environment. - ICES mar. Sei. Symp., 201: 21-34. During metamorphosis, fish larvae undergo rapid changes in external appearance and dimensions of body parts. The juveniles closely resemble the adult form. The focus of the present paper is the comparison of stages of development of fishes belonging within different taxa in a search for general patterns. The hypothesis that these patterns reflect the priorities of vital functions, e.g., feeding, locomotion, and respiration, is tested taking into account the size-dependent influences of the aquatic environment on the larvae. A review of some literature on ailometries of fish larvae is given and related to the rapidly changing balance between inertial and viscous forces in relation to body length and swimming velocity. New data on the swimming of larval and juvenile carp are presented. It is concluded that the patterns of development and growth shows in many cases a close parallel with the successive functional requirements. J. W. M. Osse and J. G.

  • 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.

  • REPRINTED from KOOLEWONG Vol
    REPRINTED FROM KOOLEWONG Vol. 4, No. 2 The Lungfish-Creature from the Past by GORDON C. GRIGG The survivor from prehistoric times, the salmon-fleshed Queensland lungfish, may fall victim to agricultural destruction of its habitat. Along the more remote reaches of Queensland's Burnett River, particularly toward evening, it is easy to believe that prehistoric creatures exist in the still, dark pools. Yet despite the heavily primeval atmosphere of the river it has so far produced only one genuine survivor from prehistoric times-the Queensland lungfish, Neoceratodus forsteri. Dissection of a lungfish (above) reveals the structure of its single lung. The lungfish also has a set of gills and can breathe air or water at will. Photo by Gordon C. Grigg. Fossil evidence suggests that this fish has remained essentially unaltered by any evolutionary processes for at least the last 150 million years. The lungfish is a member of an extraordinary group of fishes, the Dipnoi, which have lungs as well as gills, allowing them to breathe air as well as water. Of the once widespread Dipnoan fish, only three survive today: Neoceratodus in Queensland, Protopterus in Africa and Lepidosiren in South America. Neoceratodus appears to be more primitive than its overseas cousins. It is the closest surviving relative of the fish from which the first land vertebrates, the labyrinthodonts, arose about 325 million years ago. This makes it of particular interest to zoologists. The Queensland lungfish inhabits waterholes in rivers where the channel widens, deepens and flows more slowly. During the day it remains on the bottom and can sometimes be seen in the shade of overhanging trees.

  • Nearshore Ichthyoplankton Associated with Seagrass Beds in the Lower Chesapeake Bay
    MARINE ECOLOGY - PROGRESS SERIES Vol. 45: 33-43, 1988 Published June 20 Mar. Ecol. Prog. Ser. P -- -- Nearshore ichthyoplankton associated with seagrass beds in the lower Chesapeake Bay John E. Olneyl, George W. ~oehlert~ ' Virginia Institute of Marine Science and School of Marine Science. College of William and Mary, Gloucester Point, Virginia 23062. USA Southwest Fisheries Center Honolulu Laboratory, National Marine Fisheries Service. NOAA. 2570 Dole Street. Honolulu, Hawaii 96822-2396, USA ABSTRACT: Estuaries serve as important nursery habitats for larvae and juveniles of many species of fishes and invertebrates. Within the estuary, however, partitioning may occur among main channel. mud flat, tidal creek, and vegetated habitats. In this study we describe the egg, larval, and juvenile fish assemblages in shallow areas of submerged aquatic vegetation (SAV) of the lower Chesapeake Bay and compare them with those over the adjacent, shallow sand habitat. Densities at night over all habitats were about 1 order of magnitude higher than daytime densities, and were highest in summer. The SAV habitats were not important spawning sites for species with pelagic eggs, but were important for species brooding eggs or with demersal eggs. Overall, collections were dominated by the bay anchovy Ancl~oa mitchdh, but contained many species not commonly found in the midchannel ichthyoplankton described in earlier studies; these include the croaker Micropogonias undulatus, rough silverside Membras martinica and northern pipefish Syngnathus fuscus. Conversely, the weakfish Cynoscion regaljs was rare in our collections as compared to main channel sampling areas. Our results suggest that SAV areas do not play an important nursery role for pelagic eggs and early larvae, which may suffer increased predation by planktivores in these areas.

All the species were recorded for the first time in the western Algerian coast in this host. Furthermore, Lepidauchen stenostoma and Hysterothylacium rhacodes are reported for the first time in the western Mediterranean. Magnibursatus bartolii , Zoogonus rubellus , Dichelyne tripapillatus , Ascarophis sp. and Scolex pleuronectis provide a new host record in Lithognathus mormyrus from the Mediterranean Sea. Epidemiological indexes (pre - valence, abundance and mean intensity) were calculated for each helminth species identified in this fish. The Algerian west coast shows the highest value in the helminth species richness among all the Mediterranean coasts. KEY WORDS Helminthfauna; Lithognathus mormyrus ; Mediterranean Sea; Sparidae.

Academic Editor: Wayne O’Connor Received: 10 June 2016; Accepted: 29 December 2016; Published: 9 January 2017 Abstract: The aim of this study was to evaluate the newly-developed juvenile fish shelter (JFS) for its ability to increase prey survival and to improve species diversity in a freshwater ecosystem. An experiment was performed in an outdoor large-scale mesocosm three times from 2011 to 2012 by comparing the responses to adjustment as a function of the volume of JFS in the control and experimental groups. Analysis results of the environmental monitoring over three periods indicated only minor differences in the physicochemical characteristics of the water quality and phyto- and zoo-plankton biomass, thereby enabling a comparative analysis of the feeding ecology. However, the water temperature exhibited large fluctuations, ranging from 16.4 to 27.6 ◦C, and high water temperature conditions (Period 1, 25.6 ± 2.0 ◦C) enhanced the predation activity of the piscivorous fish Coreoperca herzi (C.

TITODE bfoRXrs i Hjdrobiologie-UR 2C Centre Orstom de Cajenne BP 163 97323 Cajenne Cedex i France 3 L .%ESTRACT: The larval and juvenile fish of the Cayenne river estuary (French Guiana, South herica) were sampled at two stations from June 1989 until October 1990. A total of 52,989 individuals from 39 species, some still incompletely identified, were collected. Three families, Engraulidae, Gobiidae and Sciaenidae, accounted for over 97% of the total number of juveniles. The analysis of data over his period showed low diversity, and a difference in diversity benveen i the two sampling locations (H = 1.24 and 1.68). The results conform to some theoreticd models of abundance that suggest a relative equilibrium of juvenile assemblages. In contras, the seasonal variations in diversity and abundance and the results of a correspondence analysis showed significant differences in species distribution and in their relative abundance at the two sampling locations at certain periods, mainly in the rainy season. Our study indicates that. in spite of an apparent stability, the year to year variation in salinity and freshwater inputs could affect juvenile recruitment of some species and induces modifications in the composition of larval and juvenile estuarine fish assemblages.
