Summary: Irish freshwater aquaculture has the potential to aid food security, but its expansion has been hindered by environmental EU directives. A peatland-based recirculating aquaculture multi-trophic pond system (RAMPS) was developed to assess its sustainable development while adhering to organic aquaculture practices. The collapse of the algal population within the system was observed, and further investigations identified zoosporic parasites as potential causes. Additional research is needed to monitor and mitigate these parasites.

Summary: This study aimed to explore the potential of different freshwater invertebrate species for bioaccumulation testing of ENMs and provide guidance for using bioaccumulation endpoints derived from studies using aquatic invertebrate species in the risk assessment process. The results suggest that amphipods are suitable test organisms for bioaccumulation testing of ENMs, as they allow for examination of independent exposure pathways. This approach may allow a waiver of further vertebrate tests due to the worst-case scenario of the amphipod test.

Summary: This paper examines the main determinants of agricultural land prices variations in Czech farm-land and how urbanization, lease payments, and subsidies influence these variations. The study uses the Augmented Dickey Fuller Test to investigate the existence of a unit root and the co-integration approach, specifically the Johansen procedure, to estimate the long-run relationship between farm-land value and these elements. The analysis confirms the existence of this long-run relationship. Short-run fluctuations in agricultural land prices are explained using the Error Correction Model, with urbanization identified as the most important variable. This information can help regulators avoid potential instabilities and volatility in agricultural land values, contributing to sustainable land use.

Summary: The pet trade serves as an important pathway for the introduction of aquatic non-native species, with Indonesia playing a significant role in this trade. A survey of the Indonesian market and aquaculture reveals the volume of trade and the customer countries involved in the import of South American river stingrays. Analysis of the climate similarities between the native range of these species and Indonesia identifies several areas suitable for their establishment, and the presence of established populations in the Brantas River confirms this. The unregulated culture of these stingrays poses a risk to wildlife, highlighted by the first recorded case of envenomation caused by Potamotrygon spp. outside of South America. Continuous monitoring and risk mitigation measures are strongly recommended.
