Article

In 1768, Martinus Slabber collected the only specimen ever found of the ctenophore species mostly cited as Callianira hexagona (Slabber, 1778). After analysing the international confusing literature on this species, we conclude the nomenclatural correct name should be Callianira slabberi De Haan, 1827. The designation to Callianira was done by 19th...

Concern about fisheries impact on marine ecosystems has raised the interest in the reconstruction ofthe state of marine ecosystems and the nature of the human activities in the past. We present late 16thcentury information on the occurrence and relative abundance of biota in Dutch coastal and inland waters(50 marine fish, 13 diadromous or freshwate...
Article
The sudden disappearance of Atlantic bluefin tuna in northern Europe in the 1960's, after its frequent occurrence in the preceding period, has often been discussed in the scientific literature. Remarkably enough, the question whether the figures from the beginning of the 20th century have always been at the same high level in earlier periods, has s...
Article
Until the late 19th century, extensive beds of flat oyster Ostrea edulis populated the Central North Sea, which have vanished after intensive fisheries. At present, various initiatives are being carried out to investigate the potential to restore this former key species in the area. This historical ecological study contributes by delineating the fo...

Survey of reef fishes using of the roving diver method at 32 locations on the west coast of Bonaire (Caribbean). The results were compared to the species list (286 species) in Pattengill-Semmens (2002). Next to the invasive Lionfish Pterois sp., five species were added to this list. Additionally, we compared some more recent data from the REEF.org...

At the start of the 20 th century, concern about depletion of fish stocks triggered North Sea fishery investigations by several countries. During these early trawl surveys, naturalists on board not only recorded fish but also invertebrates. The benthic data of the English RV Huxley and the Dutch SS Wodan bottom and otter trawl surveys were (partly)...

In het vorige Zeepaard werd deel 1 gepubliceerd van de inventarisatie van de wateren van Harlingen, die de auteurs in drie achtereenvolgende jaren uitvoerden. Voor u ligt het tweede deel van deze inventarisatie. De vondsten aan de zeezijde van de sluizen staan hierin centraal. Voor inleiding en algemene toelichting op de inventarisaties, en vondste...

In de jaren 2015-2017 inventariseerden de auteurs drie maal de wateren van Harlingen. In 2015-2017 the authors held an inventory of aquatic life in the town and harbours of Harlingen (province Friesland, The Netherlands). The biodiversity in these waters was surprisingly high. In total 51 species from freshwater, brackish water and salt water were...

The invasive sponge Celtodoryx ciocalyptoides has become widespread in the Eastern Scheldt (Netherlands) since it first appearance around 2002. Often, the sponge occurs in two distinctive morphs: with a fistulose (fig. 1) or with a smooth surface (fig. 2). Smooth-surface morphs were frequently covered by brittle stars Ophiothrix fragilis. As the ar...

Only a few records exist of the sponge crab Dromia personata in the North Sea. Most records are in local languages, and have limited availability. On 11 August 2016, D. personata was found by divers in the Eastern Scheldt, a former estuary in the south-western part of the Netherlands. In the months to follow, at least four other individuals were ob...

Aboard motor vessel Neptune Frank de Graaf and Floris Bennema took part in the Oceana North Sea Expedition from 16 until 28 August, 2016. Bottom samples were taken from the Dutch part of the North Sea Continental Shelf. The malacological results are presented here. Remarkable findings were living Simnia patula (Pennant, 1777) and some fresh, single...

On 22 April 2016, at Bruinisse in the Eastern Scheldt, many specimens and egg capsules of the opisthobranch gastropod Philine quadripartita were found. A public account of the discovery led to additional observations at this and nearby locations. Egg capsules were even reported from 2015. These are the first Dutch records of live specimens with an...

General information Coral reefs and seagrass beds play a vital role in tropical marine environments. In both of these ecosystems, larger algae (macroalgae) play an important part: they provide food for herbivores, and they stabilize the structure of reefs. Algae are also remarkable in that they are responsible for the high productivity that charact...

For this paper, we critically studied diaries, field reports and scientific literature in order to pay special attention to the use of the diving helmet by Dutch scientists. Information is presented in the time frame of 1860 to 1940, among activities of other marine biologists who may be regarded as pioneers in this field as well. The context of sc...

Just like the King of Herrings the Dutch haringkoning is currently considered to be the oarfish (Regalecus glesne). This article describes a literature review of old Dutch sources which revealed that the haringkoning originally refered to the red mullet (Mullus surmuletus). As British and Dutch fishermen fished for herrings in common waters, it wou...

The 18th century physician Job Baster, made extensive studies on marine life along the Dutch coast. Between 1759 and 1765 he published his illustrated books ‘Natuurlijke Uitspanningen’ about his observations. An account that has been poorly understood to date is his description of the release of ‘hand grenade-like young’ from egg masses, which wer...

In the eighteen century Job Baster played part in the European discussion about the classification of corallines. This led to some nicely illustrated works about marine species in the south of the Netherlands published by Baster and his followers Slabber and Bomme. An effort was made to identify the species they presented, both by collecting litera...

Question (1)
Question
There is no doubt that oyster beds are beneficial to smaller fish species (e.g. gurnards and bull rout) and provide a substrate for elasmobranchs to attach their egg cases. Yet various modern sources suggest that oyster beds provide a safe nursery for various fish species, even commercial valuable ones. I never found any proof for this suggestion, is there?

The Working Group on the History of Fish and Fisheries (WGHIST) brings together marine biologists, historians, fisheries scientists, historical ecologists, and paleoecologists working on long-term (multidecadal, centennial, and beyond) changes in the marine environment. ​​​WGHIST offers a unique forum for common work on social-ecological change through time from different geographic regions as well as thematic areas and across disciplines, with the stated purpose of providing insight for current and future science, management, and policy. This includes research outcomes, as well as that on novel data sources, methodological approaches, and successful interdisciplinary work more broadly.
