Morphological and morphometric study of crustacean parasites within the genus <i>Lernaeocera</i> OMA
Van Damme, P.A.; Ollevier, F.P..
Two species of <i>Lernaeocera</i> are present in the southeastern North Sea. <i>Lernaeocera lusci</i> infects bib <i>Trisopterus luscus</i>, dragonet <i>Callionymus lyra</i> and sand goby <i>Pomatoschistus minutus. L. minuta</i> is a junior synonym of <i>L. lusci.</i>. The second valid species, <i>L. branchialis</i>, infects whiting <i>Merlangius merlangus</i>. The two species can be morphologically separated by the antennary processes, which are present in <i>L. lusci</i> and absent in <i>L. branchialis</i>. Discriminant functions allow complete separation between <i>L. lusci</i> and <i>L. branchialis</i>. There...

The composition of the fish and crustacean community of the Zeeschelde estuary (Belgium) OMA
Maes, J.; Taillieu, A.; Van Damme, P.A.; Ollevier, F.P..
Fykes were used to monitor the fish and crustacean fauna of the mudflats of the Zeeschelde between April 1995 and December 1996. Overall 38 species were recorded; the number of species was greater in the brackish water part than in the fresh water part probably due to reduced oxygen concentrations in the upper reaches of the river. In terms of wet weight, just 6 species accounted for more than 96% of the total annual catch. These species are shore crab, eel, flounder, common shrimp, sole and bass. Clear seasonal patterns in the community structure were not identified. It is argued that the selectivity of the fishing gear is mainly responsible for the dominance of a few species and the lack of a temporal structure.

Fish species of the lower Zeeschelde (Belgium): a comparison with historical checklists OMA
Van Damme, P.A.; Hostens, K.; Ollevier, F.P..
In the 19th century approximately 40 fish species (excluding freshwater species) were recorded in the lower Zeeschelde between the Dutch/Belgian border and Antwerpen. In comparison with the 19th century and the first half of the 20th century the total number of fish species in the Beneden-Zeeschelde has decreased considerably. The present checklist (1991-1993) of fishes of the lower Zeeschelde (excluding freshwater species) contains only 26 species. The fish community is composed of marine species (13), catadromous species (3), estaurine residents (9) and one anadromous fish species. Besides, 6 freshwater fis species have presently been recorded. The distribution of diadromous fishes, estaurine residents and freshwater fishes is probably greately affected...

The population dynamics of <i>Lernaeocera lusci</i> and <i>L. branchialis</i> on intermediate hosts OMA
Van Damme, P.A.; Ollevier, F.P..
The metapopulation dynamics of <i>Lernaeocera lusci</i> and <i>L. branchialis</i> on sole <i>Solea solea</i> and flounder <i>Pleuronectes flesus</i> were studied in the Dutch coastal area. Both fish species harboured large numbers of parasites when they arrived in the coastal area in the spring. Between April and June all parasites detached from the intermediate hosts and infected the definitive hosts (0+ whiting <i>Merlangius merlangus</i> for <i>L. branchialis</i>, and possibly sand goby <i>Pomatoschistus minutus</i> for <i>L. lusci</i>). Thereafter, flounder remained almost parasite-free until autumn. This suggests that <i>L. branchialis</i> has...

The population dynamics of the parasitic copepode <i>Lernaeocera lusci</i> (Bassett-Smith, 1896) on its definitive host OMA
Van Damme, P.A.; Hamerlynck, O.; Ollevier, F.P..
The mesoparasitic copepod <i>Lernaeocera lusci</i> (Bassett-Smith, 1896) was recovered from first-year bib (<i>Trisopterus luscus</i> L.) in the Voordelta (Southern Bight of the North Sea) from May until December 1989. Analysis of the seasonal abundance and of the population structure showed that transmission of infective stages to bib mainly occurred from June to September. From September to December the overall prevalence fluctuated around 70%. Maximum parasite population size (47/10<sup>4</sup>m²) and the highest total egg number were recorded in September and October, respectively. It was found that total parasite mortality was significantly influenced by mortality of hosts carrying parasites. Natural mortality...

The infection dynamics and dispersion pattern of <i>Lernaeocera branchialis</i> L. on 0+ whiting (<i>Merlangius merlangus</i> L.) in the Oosterschelde (SW Netherlands) OMA
Van Damme, P.A.; Hamerlynck, O..
Size and structure of the <i>Lernaeocera branchialis</i> population infection 0+ whiting in the Oosterschelde were studied during 1989. Two periods of successful transmission were distinguished. The first transmission wave occurs in late spring when the post-larval whiting enter the Oosterschelde. A second wave occurs in autumn. This pattern in the infection dynamics is possibly related to seasonal variations in spatial overlap of the intermediate (<i>Platichthys flesus</i>) and the final host (<i>Merlangius merlangus</i>). The dispersion pattern of <i>Lernaeocera branchialis</i> within the whiting population can be described by the Poisson distribution. Possible explanations for the observed dispersion...

The role of <i>Callionymus lyra</i> and <i>C. reticulatus</i> in the life cycle of <i>Lernaeocera lusci</i> in Belgian coastal waters (Southern Bight of the North Sea) OMA
Van Damme, P.A.; Maertens, D.; Arrumm, A.; Hamerlynck, O.; Ollevier, F.P..
A survey of the dragonet <i>Callionymus lyra</i> and the reticulated dragonet <i>C. reticulatus</i> from Belgian coastal waters (Southern Bight of the North Sea) in June 1991 revealed 34% of dragonets infected with 1-7 <i>Lernaeocera lusci</i>. This same parasite infected 9% of the reticulated dragonets (mean intensity = 1). Parasite size is host-size-dependent. Of the parasites collected from <i>C. lyra</i> 64% were gravid adults (substage X), and a significant positive relationship between the number of eggs and axial length of the parasite was found. The parasites were overdispersed within the dragonet population (<i>s²/m</i>=1.67).
