  • The Science of Ichthyology, Properties of Water & What IS a Fish Anyway?

    Zoology 1450

    Chapter 1 (Helfman, Collette & Facey)

  • History of Ichthyology

  • Introduction: Ichthyology the ScienceHistory

    (Anient Greece) Aristotlefirst scientific description of fish (118 spp.)

    1500 Guillaume RondeletDe Piscibus Marinum (244 spp.)

    1686 George Markgraf'sNaturalis Brasilae (100 spp.)

    1686 John Ray & Francis Willughby Historia Piscium (>400 spp.).

    ~1735 Linnaeus develops binomial nomencalture (two name, genus speices) Peter Artedi The father of ichthyology"a student of Linnaeus who identified five orders of "fishes" (includingcetaceans) and divided those into genera. Artedi got drunk and drowned in Amsterdam canal (Linnaeus published his manuscripts posthumously.)

    1700s-1800sGlobal specimens deluged museums.

  • More History...1780s Marcus Elieser BlochIchthyologia as a series of volumes of plates. Johann Gottlob Schneider pub. M. E. Blochii Systemae Ichthyologiae (1,519 spp.)

    1800s Georges Cuvier'sRegne animal distribu daprs son organisation (key step forward for fish classification) Cuvier also worked with his student Achille Valenciennes to produce the 22-volume Histoire Naturelle des Poissons (never completed) yet 4,514 spp.

    1800s Albert GntherCatalogue of the Fishes of the British Museum >6,800 spp.described (another 1,700 mentioned).

    1859 Charles DarwinOrigin of the Species, animals placed within a common genus shared ancestral lineage.

    ~1900 David Starr Jordan (greatest ichthyologist at time)wrote 650 articles and books on fish, also president of Indiana and Stanford Universities.

  • Still more history...1896-1898 B.W. EvermannFishes of North America describedALL fish known in N. America and Panama at the time (4 volumes).

    1947 Leo BergRussian paleoichthyologist who combined study of fish and fossil records, Classification of Fishes, Recent and Fossil. First introduced the cocept of iformes to endings offish orders, eliminated confusion.

    1966 Greenwood et al.produced the first modern classification of the majority of present day fishes.

    1994 Balon et al.compilation of contributions to ichthyology by women scientists.

  • Resources...Many resources for fish information.Texts: Moyle and Cech 1996, Bond 1996, Bone 1994.Journals: Copeia, Transaction of the American Fisheries Society, North American Journal of Fisheries Management, Aquaculture, Journal of the World Aquaculture Society, North American Journal of Aquaculture, Journal of Fish Biology, Journal of Ichthyology, etc...Internet: www.fishbase.org, www.aquanic.org, www.afs.org (You can find almost anything out there, but read CAREFULLY!! Some stuff is still trash!)

  • What is a fish??Classic definition:-Any of numerous cold-blooded aquatic vertebrates of the superclass Pisces, characteristically having fins, gills, and a streamlined body and including specifically, and...-Any of the class Osteichthyes, having a bony skeleton, and...-Any of the class Chondrichthyes, having a cartilaginous skeleton and including the sharks, rays, and skates.

    Although this is all accurate...we will find that fish are considerably MORE!!

  • Fish similarities...Vertebrate (or chordate)Gills PoikilothermicFinsScalesAlways exceptions!

  • Fish Diversity>25,000 speices (spp.) of fish today(note: fish is singular, fishes more than one spp.) 41% freshwater58% seawater~1% both (neither)

  • Where Do Fish Live?Great environmental diversity = many fish spp.Earths surface~70% oceans, part of remaining 30% freshwater.

  • Fish can live about three miles above sea level (15,000 feet)...

  • ...to nearly seven miles beneath it (35,000 feet).

  • Fish live in sub-zero temperatures in Antarctica...

  • ... to hot spring water of more than 100F.

  • Water Quality in Aquaculture

  • TopicsWater CharacteristicsWater SourcesWater BalanceChemicalsStratification

  • Water quality determines the success or failure of fish culture.

  • Eat (Sleep)BreatheExcrete wastesReproduceTake in and lose saltsQ: Why is water quality important??

    A: Fish perform ALL bodily functions in water!

  • Water SourcesWells and springsGroundwaterStreams, rivers and lakesMunicipal

  • WellsAdvantagesUsually constant temperatureUsually free of wild fish and insects DisadvantagesWill require pumping unless artesianMay have high levels of CO2

  • SpringsAdvantagesNo pumping costsRelatively stable temperatureDisadvantagesFlow rates may vary with seasonInsects or fish may inhabit

  • Groundwater/run-offAdvantagesNo pumping costsDisadvantagesLevel may vary with seasonDifficult to drain

  • Streams, Rivers & LakesAdvantagesLarge quantities may be availableDisadvantagesTemperature varies widelyExcess nutrients may be presentUnwanted fish and insectsQuality is questionable

  • MunicipalAdvantageHigh qualityDisadvantagesChlorine or chloramine presentExpensive

  • Water Quantity

  • Groundwater Availability in Florida
