The age and rate of growth of the flounder from inshore shallow waters of the Gulf of Gdansk (from shore to 1-m depth) have been investigated. Mainly the flounder from 0 and 1-year age group exists in this zone. Flounders from 0-year age group enter shallow waters of the Gulf of Gdansk in June or July. They stay in this area till the end of the year. Flounders from 1-year age group are represented in the investigated zone all year. Bigger individuals from this group migrate into deeper waters.

The aim of the present study was to verify the feasibility of using live Artemia salina nauplii embedded with fluorochromes for the mass marking of pike Esox lucius (L.) larvae. In the experiment, pike larvae 6 days post hatch were fed ad libitum with nauplii dyed with 600 ppm tetracycline hydrochloride (TC) or 200 ppm alizarin red S (ARS) for 3 or 6 days. The highest percentage of marked fish (100%) and the best quality of this marking was found in the groups fed A. salina stained with TC for either 3 or 6 days. In groups fed A. salina stained with ARS for 3 or 6 days exhibited a lower percentage of marked fish (ranging from 76.7–88.3%). No significant differences between experimental groups were noted regarding survival rate, final body weight and length of the reared pike larvae.

Celem badań było sprawdzenie możliwości wykorzystania żywych naupliusów Artemia salina barwionych uprzednio w dwóch fluorochromach do masowego znakowania larw szczupaka Esox lucius (L.). W eksperymencie sześciodniowe larwy szczupaka karmiono naupliusami solowca barwionymi w chlorowodorku tetracykliny (TC) w stężeniu 600 ppm oraz alizarynie red S (ARS) w stężeniu 200 ppm, odpowiednio przez 3 lub 6 dni. Najwyższy procent znakowanych otolitów/ryb (równy 100%) i wysoką jakość znaczków uzyskano w grupach, w których podawano naupliusy barwione TC zarówno przez 3, jak i 6 dni. Z kolei w grupach otrzymujących pokarm barwiony ARS przez 3 lub 6 dni odnotowano niższy odsetek znakowanych osobników (w zakresie 76,7–88,3%). Nie stwierdzono jednocześnie istotnych różnic statystycznych między wartościami przeżywalności oraz końcową masą lub długością ciała larw szczupaka w poszczególnych grupach doświadczalnych.

The Oligocene (Rupelian) Byram Formation (Vicksburg Group) in Alabama, USA, is divided into three members, including (in ascending order) the Glendon Limestone, unnamed marl, and the Bucatunna Clay. The Oligocene marine units in Alabama have been historically under-investigated, but bulk samples recently obtained from Glendon Limestone Member exposures at site AWa-9 in Washington County yielded 20 unequivocal elasmobranch and teleost taxa. This surprisingly diverse paleofauna, based on isolated teeth, bones and otoliths, includes the new taxon, Gobiosoma? axsmithi sp. nov., as well as “Aetomylaeus” sp., Albula sp., Aplodinotus gemma Koken, 1888, Ariosoma nonsector Nolf and Stringer, 2003, Balistidae indet., Citharichthys sp., Myliobatoidei indet., Diretmus? sp., Hemipristis sp., Negaprion aff. N. gilmorei (Leriche, 1942), Pachyscyllium sp., Paralbula sp., Physogaleus sp., Preophidion meyeri (Koken, 1888), Sciaena pseudoradians (Dante and Frizzell in Frizzell and Dante, 1965), Sciaenops? sp., Sparus? elegantulus Koken, 1888, Sphyraena sp., and Syacium sp. Additional remains were recovered but could not be identified beyond undetermined Elasmobranchii or Teleostei. All these taxa represent first occurrences within the Glendon Limestone Member in Alabama, and the “Aetomylaeus” sp., Pachyscyllium sp., Paralbula sp., and Sciaenops? sp. specimens represent the first occurrences of each in the Oligocene of the Gulf Coastal Plain of the USA. We also report the first record of Oligocene Paralbula Blake, 1940 teeth, and the first occurrence of an Oligocene member of the Balistidae in the Western Hemisphere. This marine vertebrate assemblage indicates that the Glendon Limestone Member at site AWa-9 represented a subtropical to temperate, middle shelf paleoenvironment with a paleowater depth interpreted as 30–100 m.

In this study, the relationships between otolith length and fish length (total, fork and standard) of a total of 251 specimens of the Capoeta capoeta umbla (Heckel, 1843) (Cyprinidae) species inhabiting Hazar Lake were examined.The otolith lengths were measured for the whole otolith (in an anterior to posterior direction) by using an ocular microscope with a micrometer.There was a strong relationship between the otolith lengths and fish lengths obtained.

Celem badań było określenie związku między długością otolitów a długością ciała (analizowano długość całkowitą, długość ciała i długość ogonową) Capoeta capoeta umbla (Heckel 1843) (Cyprinidae). Przebadano 251 osobników zamieszkujących jezioro Hazar, położone w środkowej Turcji. Próby ryb pozyskiwano w okresie od listopada 1996 do października 1998, z czterech stanowisk znajdujących się w różnych częściach zbiornika (rys. 1). Do weryfikacji istotności związku długość ryb - długość otolitów użyto równania regresji prostoliniowej. Stwierdzono, że zależności te były wysoce istotne statystycznie, a współczynniki korelacji równań regresji opisujących te zależności przyjęły wartości od 0,90 do 0,94 (rys. 2 - 10). Zależności te były wysoce istotne statystycznie zarówno dla samic, jak i samców tego gatunku (tab. 1).

Fish remains described from the early Miocene lacustrine Bannockburn Formation of Central Otago, New Zealand, consist of several thousand otoliths and one skeleton plus another disintegrated skull. One species, Mataichthys bictenatus Schwarzhans, Scofield, Tennyson, and T. Worthy gen. et sp. nov., an eleotrid, is established on a skeleton with otoliths in situ. The soft embedding rock and delicate, three−dimensionally preserved fish bones were studied by CT−scanning technology rather than physical preparation, except where needed to extract the otolith. Fourteen species of fishes are described, 12 new to science and two in open nomenclature, representing the families Galaxiidae (Galaxias angustiventris, G. bobmcdowalli, G. brevicauda, G. papilionis, G. parvirostris, G. tabidus), Retropinnidae (Prototroctes modestus, P. vertex), and Eleotridae (Mataichthys bictenatus, M. procerus, M. rhinoceros, M. taurinus). These findings prove that most of the current endemic New Zealand/southern Australia freshwater fish fauna was firmly established in New Zealand as early as 19–16 Ma ago. Most fish species indicate the presence of large fishes, in some cases larger than Recent species of related taxa, for instance in the eleotrid genus Mataichthys when compared to the extant Gobiomorphus. The finding of a few otoliths from marine fishes corroborates the age determination of the Bannockburn Formation as the Altonian stage of the New Zealand marine Tertiary stratigraphy.
