Contribution à l'étude du plankton dans le port d'Ostende
Provedor de dados: 27
Autores: De Pauw, N.
Resuming our proper observations and taking in account the collected data in the literature we can conclude that: (1) diatoms and copepods are the principal components of the Oostende plankton; (2) concentration of zoo- and phytoplankton is highest in summer and autumn; (3) there is a physico-chemical and biological gradient between the front and rear of the port. The gradation is decreasing for salinity, oxygen concentration, pH, number of marine species and the total biomass. The gradient is increasing for temperature and freshwater organisms; (4) several observed species are new to the Belgian coast: 4 copepods, 5 ciliophores, 1 cumacean and 2 diatoms; (5) although the number of species typical for a port is small, several species (observed in large...

Etude des migrations nycthémérales du zooplankton dans un milieu marin peu profond
Provedor de dados: 27
Autores: Daro, M.H.
The Sluice-dock of Ostend, a shallow (1.5 m) marine biotope of 86 ha stays closed during some 6-7 months of the year and is not influenced by the tides. During 24 h cycles the nycthemeral migrations of the zooplankton at 5 depths in a watercolumn of 1 meter were studied in relation to several environmental factors: water temperature, dissolved oxygen, pH and chlorophyll content. The photosynthesis shows a minimum during the night and shows a maximum during the late afternoon, at which time the water-temperature is also maximal. Holo- and meroplanktonic organisms migrate towards the surface around 3-5 o'clock a.m., at which time the chlorophyll content is minimal, hence our hypothesis of nocturnal grazing, this phenomenon perhaps combined with a nocturnal...

The Sluice-dock at Ostend
Provedor de dados: 27
Autores: Polk, P.
The sluice-dock at Ostend is an artificial lagoon (1.5 m deep and with an area of 86 ha) connected to the harbour of Ostend and the North Sea by sluices (vannes). At low tides, during spring tide, the whole dock can be emptied, washing out the planktonic biomass. As an oyster culture exists in this biotope, applied and fundamental research is done. Planktonic larvae of oyster predators can be eliminated from the biotope by washing out the whole water volume during their bloom and replacing it by new sea-water. The oyster pest &lt;i&gt;Crepidula fornicata&lt;/i&gt; (introduced with oyster spatfall from the Netherlands and reproducing heavily in the sluice-dock, otherwise not occurring along the Belgian coast) is controlled in this way (before: 15,746...

&lt;i&gt;Monhystera parelegantula&lt;/i&gt; (De Coninck,1943) was collected from the sediment of the Sluice-dock, a euhaline-polyhaline lagoon near the harbour of Ostend (Belgium). The species was cultivated in large numbers on a bacto-agar medium with bacterial growth. Embryonic growth was studied at 30 °C and 30 promille S. Maximum embryonic length-growth occurs at the vermiform stage. Post-embryonic length-growth, studied at 25 °C and 30 promille S, is a linear function of time and may be expressed as l = 160.46 + 29.55(t-t&lt;sub&gt;o&lt;/sub&gt;), where t&lt;sub&gt;o&lt;/sub&gt; = time at the beginning of development; t and l = time (d) and length (µm).

Ecometabolism of a shallow marine lagoon at Ostend (Belgium): 2. Zooplankton dynamics
Provedor de dados: 27
Autores: Podamo, J.
The food chain of plankton at the Sluice-Dock is reduced to the simple system "producers-primary consumers". The role of zooplankton is most important only for a short time, namely in May, when it restricts the development of phytoplankton by its grazing activity, and becomes the main source of nutrients due to its excretory activity. After the disappearance of most of the zooplankton biomasses, caused by a mortality that is not due to predation, the phytoplankton can again develop. At other times of the year, the zooplankton activities such as production, grazing, excretion, and respiration only represent 1% of the total plankton activity.

Relation entre des populations successives de phytoplancton et de bactéries hétérotrophes dans le Bassin de Chasse d'Ostende (Belgique), en 1971
Provedor de dados: 27
Autores: Podamo, J.
When the sluices of the "Bassin de Chasse" in Ostend were closed, on the 31th March 1971, we observed an important decrease of the number of heterotrophic marine bacteria in the water: from 5.10&lt;sup&gt;5&lt;/sup&gt; b/ml on 31th March to 10&lt;sup&gt;3&lt;/sup&gt; b/ml on 15th May. This can be interpreted as reflecting the consumption of organic material supporting the growth of the bacteria by the bacteria themselves. The new bacterial populations appearing then were closely related to the phytoplanktonic populations appearing just before them. This relation probably reflects the dependance of the bacteria to the new organic material of the dead phytoplankton cells.

Feeding experiments in which the zooplankton fraction of the Sluice-dock smaller than 200 µm is offered to &lt;i&gt;Acartia tonsa&lt;/i&gt;, the dominant calanoid of this biotope, show that it feeds on the nauplii of &lt;i&gt;Canuella perplexa&lt;/i&gt;, the dominant benthic harpacticoid. The ecological implications of this carnivorous feeding, occurring in the presence of natural phytoplankton concentrations, are briefly discussed.

Evolution des populations de bactéries marines hétérotrophes au bassin de chasse d'Ostende (Belgique) en 1971
Provedor de dados: 27
Autores: Podamo, J.
A bacteriological study of the water of the "Bassin de Chasse" of Ostend (Belgium) has been done from 31 March till 29 July 1971, when the dock has been kept closed. The results show a succession of different populations of heterotrophic marine bacteria. This conclusion appears from different results: &lt;ol&gt;&lt;li&gt;total count of bacteria; &lt;/li&gt;&lt;li&gt;separate count of bacteria forming white and coloured colonies; &lt;/li&gt;&lt;li&gt;rough determination (morphology and Gram-reaction) of some bacteria. &lt;/li&gt;&lt;/ol&gt;These population-variations could be explained by variations in the organic matter of the water.

Autores: Bergmans, M.
The life-cycle of the harpacticoid copepod &lt;i&gt;Tisbe furcata&lt;/i&gt; (Baird, 1837) at 18°C was studied quantitatively. Stage durations were determined by two different methods, using synchronous cohorts. Combined nauplius stages last for 80.4h; the successive copepodite stages take 23.0, 23.2, 28.0 (females) to 23.2 (males), 33.4 (females) to 24.2 (males) and 48.8 (females) to 34.7 (males) h, respectively. Females develop more slowly but more synchronously than males. Age-specific survival and fertility rates were used to calculate the stable stage distribution in an exponentially growing population. From life-table data the following demographic parameters were computed: intrinsic rate of natural increase...

Swimming behaviour patterns in certain benthic harpacticoids (Copepoda)
Provedor de dados: 27
Autores: Hauspie, R.; Polk, Ph.
During an investigation on the fouling of artificial substrata in a brackish-water biotope at Oostende (=Ostend), Belgium, it was found that some harpacticoid species, until now considered benthic, become pelagic at certain times. Also, we observed that these harpacticoids were swimming during certain periods and then were found in the plankton. Some observations about this phenomenon are discussed in this paper.

Outdoor mass production of marine microalgae for nursery culturing of bivalve molluscs
Provedor de dados: 27
Autores: De Pauw, N.; De Leenheer, L.
Nursery rearing of bivalve molluscs as the intermediate step between the controlled production of larvae in hatcheries and non-controlled growing-out in the wild, is a practice in modern shellfishery management which receives more and more attention. A major bottle-neck in the culturing process of the postlarval bivalves is, however, the production of large quantities of marine microalgae suitable as food for the growing spat. Experience was gained by the authors in small 1 m&lt;sup&gt;2&lt;/sup&gt; outdoor units with induced blooms of natural phytoplankton. The cultures were run either as a turbidostat or as a chemostat with discontinuous or continuous harvesting.Natural seawater (25-32°) was enriched with inorganic (commercial), or organic fertilizers...

The oyster culture, flourishing along the Belgian coast at the beginning of the century, perished entirely in the course of two World Wars. In 1956, it was taken on again intensively in the Scour Basin of Ostend. If we consider the obtained results with the affination of Flat and Portuguese oyster, this 86 ha closed basin, is of an exceptional productivity. Essays on the understanding of the origin of calcified oysters, done from 1960 until 1966, turned out to be very promising and an integral oyster culture from the larvae up to the adult oyster could be observed. In any case the last few years, eventhough compared to before a normal emission of larvae of &lt;i&gt;Ostrea edulis&lt;/i&gt;, there has not been a fixation of the origin. Regular samples of...

Autores: Podamo, J.
Nitrogen nutrients being, at least at some periods of the year, a limiting factor of primary production in the Sluice-Dock at Ostend, the production or consumption of ammonium and nitrate by the benthic bacterial communities plays an important role in the dynamics of the ecosystem. A methodology is developed to evaluate the fluxes of carbon and nitrogen associated with the microbiological activity and the physical mass transfer in the sediments.  It is based on the analysis of vertical concentration profiles of pertinent substances in the sediment, completed with some direct &lt;i&gt;in situ&lt;/i&gt; measurements of microbiological activity.  This methodology is applied to denitrification, total heterotrophic activity, and nutrification in the two types...

The difference of phototropism and phototaxis of both molluscs influenced their fixation. The orientation of both molluscs is towards the incoming light-direction, less pronounced when the light-density to the center of the tile is decreasing. The density of the populations of oysters is increasing towards the center of the tiles by decreasing light-intensity, the density of the &lt;i&gt;Crepidula&lt;/i&gt;-population decreasing towards the center of the collector.  The competition of both organisms in relation to space, is, under the opposed influence of the light, less than described in the literature. Theoretically it is possible to separate &lt;i&gt;Crepidula&lt;/i&gt; and oyster-fixation, using this property. Statistical analysis corroborated our...

1. For the first time, &lt;i&gt;Crepidula fornicata&lt;/i&gt; was observed in Belgium on 28-9-1911; in 1959, it became an oyster pest. 2. It was first introduced into Belgium with seed oysters from Great Britain. Later on, with seed oysters from the Netherlands. 3. Probably, the geographical spreading is caused by the adult animals attached to oysters. Larval propagation is responsible for local extension. 4. In the sluice-dock at Ostend, larvae occur from the middle of May till the end of November; they swim freely for a period of about 12 days. The first massive emission of larvae is observed during May and June, a second one in September. 5. The larvae settle preferentially at a depth of 65 cm. 6. Maximum settling takes place in May.

The harpacticoid fauna of a sandy sediment in the Sluice Dock of Ostend, Belgium, was dominated by a single species, &lt;i&gt;Canuella perplexa&lt;/i&gt;, that attained an average annual density of over 400 ind. 10 cm&lt;sup&gt;-2&lt;/sup&gt; in 1976 and 1977, whereas other species had a total mean density of less than 10 ind. 10 cm&lt;sup&gt;-2&lt;/sup&gt;. In the summer of 1979 a dystrophic crisis with abundant growth of &lt;i&gt;Ulva&lt;/i&gt; occurred and in March 1980 the lagoon was drained. After refilling of the lagoon, the sediment was immediately colonized by good swimming harpacticoids, that attained densities of 200 ind. 10 cm&lt;sup&gt;-2&lt;/sup&gt;.

Electron microscopic observations on the demanian system of female &lt;i&gt;Metoncholaimus denticaudatus&lt;/i&gt; Schuurmans Stekhoven and Adam, 1931 from the Sluice Dock of Ostend lead to following conclusions: 1) there is no ductus uterinus; 2) the system is not a seminal receptacle; 3) it should be interpreted as an elaborate cascade system of glands, the secretion of which serves some important purpose related to reproduction.

Ecometabolism of a shallow marine lagoon at Ostend (Belgium): 3. The role of planktonic heterotrophic bacteria
Provedor de dados: 27
Autores: Podamo, J.
In order to assess the importance of the recycling of organic matter into nutrients in the water column, the bacterial biomass was evaluated by the spread-plate counts method, and the heterotrophic activity by two methods: initial consumption rate of oxygen and anaplerotic bicarbonate fixation.  The biomass of aerobic heterotrophic bacteria does not reflect the heterotrophic activity and cannot be used as an index for this activity.  This activity is always important as a recycling process for the phytoplanktonic organic matter it is depending on. Different periods can be recognized, with varying importance (relative to other recycling factors) of bacterial activity.

Autores: Daro, M.H.; Soroa Bofill, J.
Our study about the biotope of the oyster culture, the 'Bassin de Chasse d' Ostende', has shown us that: (1) the phyto- and zooplanktonic population extraordinary abundant let suppose us that the available food is enormous. (2) The harmful organisms (&lt;i&gt;Polydora ciliata&lt;/i&gt;) and the competitors of food for the oyster (&lt;i&gt;Mytilus edulis, Balanus, Mya arenaria&lt;/i&gt;) have fixed them by a clumsy manner on the &lt;i&gt;Ostrea&lt;/i&gt;. (3) The abundance of the competitors did not restrain the growth of the mussels and the oysters. On the contrary, their growth appears to be one of the greatest of Europe.

Ecometabolism of a shallow marine lagoon at Ostend (Belgium): 1. Phytoplankton and phytobenthos dynamics
Provedor de dados: 27
Autores: Podamo, J.
Primary production parameters (numbers and identifications , pigments, photosynthesis, respiration, excretion) have been measured or estimated in a marine lagoon during 4 years. On the seasonal scale, the succession pattern shows a spring bloom in April-May, a depression in May and a summer bloom from June to August. Various nannoplanktonic flagellates are responsible for these fluctuations, which are well paralleled by photosynthetic capacity variations. Primary production was computed using a light-photosynthesis function. Photosynthetic capacities and function parameters have been determined and discussed.  On the diel scale, a strong periodicity involving natural mortality was observed and taken into account. Uptake and regeneration rates of inorganic...
