Global climate change is resulting in a wide range of biotic responses, including changes in diel activity and seasonal phenology patterns, range shifts polewards in each hemisphere and/or to higher elevations, and altered intensity and frequency of interactions between species in ecosystems.Oak (Thaumetopoea …

Soybean and fishmeal are obtained in large quantities to produce animal feed. This puts an immense stress on today’s environment. Insect larvae are seen as a possible replacement of soybean and fishmeal but there is still a large knowledge gap preventing large scale production. Many species of insect …

The main research question of this project was:Which of the four chosen algae is the most suitable for the rearing of Artemia, and ultimately Diadema antillarum larvae, at Van Hall Larenstein University of applied sciences? This question led to several sub questions which could in turn be operationalized …

In light of recent developments of the onboard ballast water treatment, WMR has developed a new protocol for the assessment of ecotoxicological effects and aims to use it as a standardised test. This study looks into the validation of this short-chronic ELS fish toxicity test, by use of the embryonic …

Coral reefs in the Caribbean have suffered massive losses of corals since the early 1980s due to a wide range of human impacts, such as explosive human populations growth, coastal pollution, global warming, overfishing, invasive species and diseases. The publication in the journal science in 2003 stated …

In the Province of Zeeland, ragworms (Alitta virens) are farmed on large scale in open rectangular (flow through systems) ponds. In April these ponds are stocked with ragworm larvae from a hatchery. The juveniles bury themselves in the sediment layer in the pond and are fed with feed pellets. Dependent …

The aquaculture sector is expanding worldwide, which gives this sector an important economic potential. A problem for the on land aquaculture sector is that there is insufficient quality feed for cultivating fish larvae and shellfish. Based on this problem the RAAQUA project was launched (Robust Algae …

Insect farming has been suggested as a good alternative to conventional livestock farming for the growing demand of food and feed production. One of the most well-known edible insects is the silkworm, larva of the silk moth (Bombyx mori). This insect is reared because of their commercially valuable products, …

Population size increase at the Balgzand intertidal in the western Dutch Wadden Sea suggested a growth decrease in both plaice and flounder populations over summer. Research into the seasonal growth of 0-group plaice, Pleuronectes platessa, confirmed this suspicion. The years 1995 and 1996 had contrasting …

The natural resources in Ethiopia are under intense pressure as a result of population growth and inappropriate farm practices. Introducing alternatives could be a step forward in reducing the impact of farming on natural resources. In Ethiopia, the pressure on water bodies and land is high which results …
