Summary: This study evaluated the environmental sustainability of Nile tilapia net-cage farms of different sizes using environmental sustainability indicators and benchmarks. Results showed that environmental sustainability is independent of farm size, with factors like feed composition, management techniques, and water temperature being more critical. The use of benchmarking tools can provide reference values for each environmental sustainability indicator, allowing improvements to reach desirable states.

Summary: Stable isotope analysis of 1257 global lakes reveals that most lakes are dependent on precipitation and groundwater, with approximately 20% of water inflow lost through evaporation and some lakes experiencing extreme evaporative losses. This highlights the importance of systematic isotopic monitoring to detect the impacts of climate change and catchment-scale variations on lake water-balance budgets.

Summary: The study introduced APOIA-Aquaculture as an indicator system for assessing Best Management Practices (BMPs) in tilapia cage farming. Results showed common deficiencies in Spatial Organization indicators, such as lack of water quality monitoring equipment and improper storage of feed. Interactions were observed among indicators of Management and Nutrition dimension and signs of deterioration in Water and Sediment Quality.

Summary: This study tested the effectiveness of a mixed-sex strategy in tilapia farming compared to the commonly used MT-treated mono-sex system. The results showed no significant differences in production and quality between the two strategies. However, the additional costs of the mixed-sex strategy resulted in lower profits, which could be mitigated by selling a portion of the removed females at a premium price.

Summary: Using sedimentary metals to assess the environmental status of three ICOLLs in northern Sydney, it was found that the highest sedimentary metal enrichment is in Australian central east coast estuaries, with only a moderate ecological risk. Comparing surficial sediment concentrations from 1996 to 2008 indicated declining metal concentrations, largely supported by subsurface metals data.

Summary: This study was conducted in Sylhet district of Bangladesh and aimed to explore the impact of different stocking densities on the growth and production of mono-sex Nile tilapia cage aquaculture. The research revealed that a stocking density of 60 fish/m(3) was the most suitable for commercial cage aquaculture of tilapia in a riverine environment in north-eastern Bangladesh.

Summary: The study investigated the variations in n-alkane and Polycyclic Aromatic Hydrocarbon (PAH) levels in the sediment of the Nile Delta coast and Bardaweel Lagoon. The total n-alkane concentrations ranged from 18.85 to 164.37 μg/g with an average of 51.98±17.49 μg/g. Similarly, the σPAHs concentrations ranged from 4.55 to 207.48 ng/g with an average of 27.89±49.82 ng/g. The results indicated variations in the sources of n-alkane and lower levels of both low and high molecular weight PAHs in the sediment samples.

Summary: Hydraulic connectivity has a significant impact on water quality, and enclosure aquaculture can deteriorate water quality by altering lake flow regime. This study used sediment dating and remote sensing images to capture the dynamics of water quality in aquaculture dominated lakes and reveal the influence of landscape pattern on water quality. The results showed that sediment dating and landscape pattern metrics can effectively provide long-term lake water quality data and contribute to water quality management in aquaculture dominated lakes.

Summary: This study utilizes oxygen and hydrogen stable isotopes as tracers to determine the sources of groundwater recharge in the central Nile delta. The isotopic data indicate that surface water is heavily influenced by evaporation, while soil water and groundwater have lower isotopic contents. The studied groundwater is found to have mixed sources, with a combination of pre- and post- High Dam construction recharge. The influence of both freshwater and seawater mixing is observed in the deep groundwater, while the shallow groundwater shows signs of evaporation.

Summary: Through quantitative analysis of the landings composition data of the Nile-Delta lakes over the past 30 years, it was found that there has been a shift in target species towards demersal opportunistic species. There has been a significant decline in species richness and landings of rare species, while opportunistic fish species such as catfish and mullet have flourished in the polluted water.

Summary: The study reveals that nearshore shallow water zones are where sand transport primarily occurs, while deeper waters along the Levant margin are the main source of sedimentation for the Levant shelf. The formation of the Levant shelf went through multiple stages, starting from an initial continental shelf off the Sinai Peninsula, then offshore Israel, and finally along the coast of Lebanon.

Summary: Investigating the impacts of climatic factors and human activities on sedimentary records of heavy metal contamination in lakes is essential. This study conducted spatiotemporal analysis on two adjacent plateau fault-bound lakes in southwest China and found that grain size and heavy metal concentrations differed between the lakes. The study also found that heavy metal burial rates were mainly influenced by sediment accumulation rates rather than heavy metal concentrations. Additionally, the study identified both natural and anthropogenic sources of heavy metals, with population density and gross domestic product playing significant roles in heavy metal contamination.

Summary: In Europe, turbot aquaculture has the potential for sustainable production, but the low tolerance to fishmeal replacement poses a challenge. This study investigated the effects of more sustainable feed formulations on the growth and feed performance of juvenile turbot. The results showed that replacing fishmeal with processed animal proteins had a negative effect on feed performance, while replacing it with terrestrial plant proteins affected the nutritional status of the fish.

Summary: Intensive fish farming has led to the spread of parasites like Sparicotyle chrysophrii, which can cause epizootics in gilthead seabream. A new model was developed to simulate the transmission dynamics of the parasite and successfully replicated its distribution within fish hosts as well as the effects of environmental factors.

Summary: This study evaluated the level of microplastic pollution in marine environments around Japan using the pollution load index, polymer risk index, and pollution risk index. The results showed low to moderate pollution levels in each area, but predicted an increase in pollution levels in the future. The study highlights the importance of taking action to prevent additional plastic pollution and the need for continued monitoring of microplastics in the environment.
