Oijen, M.J.P. van; Witte, F..

The zooplanktivorous Haplochromis tanaos spec. nov., and the morphologically very similar but insectivorous Haplochromis thereuterion spec. nov., from Lake Victoria (East Africa) are described and compared to Haplochromis diplotaenia Regan & Trewavas, 1928, a similar species which is known only from the holotype. Intraspecific variation is described for both new species. Ecological data of the new species are compared to those of known zooplanktivores and insectivores from the Mwanza Gulf area. Both new species disappeared concurrently with the Nile perch (Lates) upsurge early in the 1980's. The recent occurrence of individuals closely resembling the new species, in a different habitat close to the original one, is analysed.

Reeds enkele auteurs (Schrieken & Swennen, 1969; Vaas, 1970) hebben het voorkomen van Atherina mochon in Nederland geconstateerd. Zij vermeldden de soort uit het Veerse Meer, waar deze al in 1964 werd gevangen. Geen van deze auteurs gaat echter in op de vraag, hoe deze soort waarvan de verspreiding in hoofdzaak Mediterraan is, in het Veerse Meer gekomen is. Tijdens bezoeken aan de binnenhaven van Vlissingen, waar de electriciteitscentrale (PZEM) zijn brakke koelwater loost, bleken grote scholen van Atherina mochon aanwezig te zijn naast scholen van de gewone koornaarvis, Atherina presbyter Valenciennes, 1835. Het volgende materiaal dat in de binnenhaven verzameld werd, kon onderzocht worden: A. presbyter, 1 ex., standaardlengte 54 mm (13 december...

Late Silurian fish microfossils from Klinta and Rinnebäcks Bro (Scania, south Sweden), with remarks on the morphology of Nostolepis striata trunk scales

Vergoossen, J.M.J..

The microvertebrate faunas from ten small pieces of rock from the Öved Sandstone Formation at Klinta (1-10) yielded osteostracan, heterostracan, thelodont, and acanthodian remains, dated here as Whitcliffian. The most important age indicators are the heterostracan Archegonaspis and the thelodont zonal fossil Thelodus sculptilis. The latter taxon is also present in a small Whitcliffian fauna from the Öved Sandstone Formation at Rinnebäcks bro, together with other thelodont and acanthodian remains. From Rinnebäcks bro no previous records of Silurian fish fossils exist. In an attempt to gain a better understanding of nostolepid trunk scale variation and to develop an instrument to assess this variation, seven Nostolepis striata trunk scales from Klinta are...

Taphorn, D.C..

Rivulus marmoratus Poey, 1880 has previously been found only in south Florida, Cuba, the Bahamas, Barbuda, St. Martin and several islands off the Venezuelan coast (Curaçao, Bonaire and Gran Roque) (Hoedeman, 1958; Böhlke & Chaplin, 1968). In September of 1978, one of my students, Mr. Edgard W. Cabezas, brought me a specimen of this species that he had caught in the northern section of Maracaibo City, state of Zulia, Venezuela. We revisited the site, a poorly drained section of town near the western shore of the Straits of Lake Maracaibo, on 21.ix.1978 and 14.x. 1978, and collected an additional 19 specimens (15 of which are in my personal collection). Most of the fish were caught in shallow, brackish water (salinity 25°/00, temperature 3i°C) among...

Some remarks on the identity of the Japanese rays Raja Kenojei Müller & Henle, 1841, and Raja Meerdervoortii Bleeker, 1860

Palavras-chave: Marine fishes; Seychelles.; 42.81.

Ano: 1994

Rejecting without valid argumentation a lectotype selection for Raja kenojei Müller & Henle, 1841, by the present author (1947), Ishiyama (1967) indicated another of the four Leiden types as such. Both selected specimens are shown to represent only the different sexes of the same species, which is not conspecific with R. kenojei sensu Ishiyama et al. (= ? R. japonica Nyström, 1887) but rather with R. porosa Günther, 1847, as understood by Ishiyama. One of the R. kenojei types is referred to R. meerdervoortii Bleeker, 1860, a distinct species not identical with R. kenojei in either interpretation, and of which R. macrophthalma Ishiyama, 1950, may well prove to be a junior synonym. Müller & Henle's coloured illustration of R. kenojei, made after a...

INLEIDING Het Nederlands Instituut voor Onderzoek der Zee heeft gedurende vele jaren incidentele en gerichte gegevens verzameld van diersoorten voorkomend langs de Nederlandse kust. Daartoe werden vanaf 1932 regelmatig aan leden van de Helderse vissersvloot premies betaald voor het aanbrengen van o.a. bijzondere zeedieren. Zeevissen namen een belangrijke plaats in. Vele van de op deze wijze aangevoerde vissen werden gevangen in het kustgebied van IJmuiden tot de Duitse Bocht. In Nederland komen 137 soorten zeevissen voor, waarvan het voorkomen min of meer bekend is. De algemene soorten worden òf regelmatig door beroepsvissers gevangen en deze vangsten worden dan eens per jaar in de visserij statistieken gepubliceerd, òf regelmatig door onderzoekingsschepen...

A preliminary revision of the Belonidae

Mees, G.F..

INTRODUCTION Difficulties with the identification of some West-Indian Belonidae and an investigation into the merits of the generic name Strongylura as against Tylosurus led to a revision of the Belonidae, the result of which is published here. As will be seen on the following pages, this revision is by no means final; many problems remain to be solved, much synonymy given here is doubtful, lack of material prevented me from investigating the possible presence of slight geographic variation in the widely distributed species; some apparently valid species are left out altogether (I listed their names on p. 5) because no material has been available, and other names remain doubtful as it has not been possible to examine the type specimens. There is also the...

On Sciadeichthys (Selenaspis) Walrechti, a new South American catfish

Palavras-chave: 42.81.

Ano: 1962

Two large specimens of a hitherto unknown species of neotropical catfish have recently been found dead and washed ashore beneath the dike along the Westerscheldt near Biezelinge, Zeeland, at a mutual distance of approximately 300 meters. Both were in excellent condition and have been presented to the Rijksmuseum van Natuurlijke Historie at Leiden by Mr. B. J. J. R. Walrecht. A superficial examination already disclosed the fact that the two specimens belong to the (sub)genus Selenaspis, a well known group of catfishes inhabiting the salt and brackish shores and estuaries of the northern part of the South American continent. Some of the species are known to spawn in fresh water. The present specimens must have been transported by ship. Whether they have been...

Notes on the fishes of western New Guinea III. The fresh water shark of Jamoer lake

Ano: 1954

INTRODUCTION In 1954, during a visit to Hollandia, western New Guinea, it was rumoured that sharks had been observed in the fresh water of Jamoer Lake, at a distance by effluent river of about 130 km from the Arafoera Sea. For further information on the locality, including a map of the area, I refer to the first note in the present series (Boeseman, 1963: 231, fig. 6). With eagerness we welcomed an opportunity provided by Rear Admiral (at the time Captain) G. B. Fortuyn, then Commander-in-Chief Naval Forces Netherlands New Guinea, to pay a short visit to the isolated lake. All necessary facilities, including transportation and maintenance, were kindly furnished by the Royal Netherlands Naval Air Service and the Royal Marines. Accompanied by my colleagues...

Ray-finned fishes (Osteichthyes, Actinopterygii) from the type Maastrichtian, the Netherlands and Belgium

Friedman, M..

Ray-finned fishes are a diverse, but understudied, component of the Maastrichtian marine fauna of the southeast Netherlands (Limburg) and northeast Belgium (Liège-Limburg). The most extensive reviews of fishes from these uppermost Cretaceous deposits were made in the early and mid-Twentieth Century, but little research on this important assemblage has been executed since. The present paper provides figures and brief descriptions of fishes from the Maastrichtian type area as an aid for field identification of fossil discoveries. A simple key to common Maastrichtian fish teeth from this area is also included. All convincing records of ray-finned fishes from the Maastrichtian of the Netherlands and Belgium, inclusive of the Mons Basin, are teleosts, and...

Collections of freshwater-fishes, made in recent years in Suriname, have yielded four species of Auchenipteridae and ten species of Pimelodidae. Of the latter, two species, viz., Phractocephalus hemioliopterus and Pimelodus heteropleurus, are additions to the list given by Mees (1974: 237238), but the occurrence of Phractocephalus hemioliopterus in Suriname had already been mentioned by Geijskes (1973) and was thoroughly discussed by Boeseman (1983).

Parker, H.W.; Stott, F.C..

ABSTRACT The inshore shoals of basking sharks that appear in spring off the western seabord of Europe have been variously claimed to be part of a seasonal south to north migration, or local, perhaps nuptial, aggregations. The decline in the catches of the Achill Island Fishery in the last decade suggests that the size of the shoals has diminished there. Size/frequency analysis of available records shows a midsummer peak of specimens with a mean length of 3.09 m and a mid-winter peak at 3.52 m; the difference is significant and is ascribed to growth. From this value, coupled with the recorded maximum and minimum sizes, a hypothetical asymptotic growth-curve is calculated. Comparison of this age/length relationship with the observed relationship between...
