Summary: This study provides baseline data on microplastic pollution in commercially important fishes from the coastal and offshore waters near Kyushu, Japan. The findings show that pelagic fish have higher levels of microplastic contamination compared to demersal fish, and the contamination is influenced by habitat depth, type, and fish species.

Summary: This study observed microplastic (MPs) contamination in water samples and gastrointestinal tracts of 127 fish species from Karachi coast, Pakistan. The most dominant types of MPs were fibers, pellets, and fragments, and their abundance varied among species. The study highlights the need to investigate the origin, composition, interaction with organisms, and the impact of consuming fish contaminated with high levels of MPs on human health.

Summary: The concentrations of heavy metals in seafood were assessed, and their potential risks to human consumption were evaluated. The study found that the levels of certain heavy metals in fresh and dried fish were below the maximum residue limits set by regulatory bodies. However, there were variations in the concentrations of heavy metals in different fish species, highlighting the need for further risk assessment.

Summary: The study investigated the H2O2 concentration and water quality parameters in a large artificial lake near a metropolitan city, finding that the H2O2 concentration in summer was over three times higher than in winter. The lake produced more H2O2 during daylight hours compared to streams, with the lowest production rates in dark conditions. Exposure to external substances, such as heavy metals and antibiotics, increased the generation of H2O2, with antibiotics having a more pronounced effect.

Summary: The study examined the synchronous response of Dosidicus gigas and Trachurus murphyi habitat patterns along the Chilean waters to different-intensity El Nino events. Results showed that environmental factors were significantly correlated with the Nino 1 + 2 index, affecting the suitable habitat areas and distribution patterns of the species. Different El Nino intensities strongly influenced the habitat patterns by changing the regional marine environment.

Summary: This study describes the initial development of the red-bellied pacu fish, focusing on its morphological, meristic, and morphometric characteristics. The results show that the most significant changes in P. brachypomus occur during the transition from the flexion stage to the juvenile period, indicating changes in behavior, foraging, and physiology.

Summary: The experiment showed that the lead and chromium mixture had an impact on SOD in the liver of Labeo rohita, with slightly higher activity in the Pb+Cr group after purification. The SOD had maximum activity at pH 6.5 and 7.0, and temperature also significantly affected its activity.

Summary: The global fisheries and aquaculture production has increased significantly due to the development of fishing technologies, resulting in a large amount of fish waste being produced, creating economic and environmental concerns. With the increasing focus on circular economy, utilizing fish waste could represent a sustainable strategy for a circular bioeconomy.

Summary: Electronic waste sites pose a risk of heavy metal pollution, especially when the metals enter nearby environments. The Korle lagoon, being the biggest e-waste burning site in Ghana, is receiving waste effluents and facing the risk of heavy metal contamination in the water. Despite being considered biologically dead, the lagoon still supports small-scale fishing activities. This study found that consuming fish from the Korle lagoon poses higher health risks due to elevated concentrations of heavy metals, compared to fish sold in Ghanaian markets. Monitoring programs and environmental risk management are needed to ensure human food safety.

Summary: In the US, 70% of the population lives in snowy and icy regions where road deicing salts are heavily used to reduce vehicular accidents, leading to increased freshwater salinity. There is an urgent need to reassess protection thresholds for freshwater biota and drinking water supplies, and to adopt best management practices to curb salinization caused by deicing salts.

Summary: This study examined microplastics in the gastro-intestinal tracts of 160 fish species from Nigerian coastal waters and estimated the annual microplastic intake by the adult human population. Microbeads and fragments were the most commonly found types of microplastics, with sizes mostly below 1000 μm. It was estimated that a significant portion of these microplastics could translocate from the fish guts to human muscles and other organ tissues. The annual intake of microplastics varied among different fish species, with higher intakes observed for those with broader habitat and feeding preferences.

Summary: Mauritania became a lower-middle-income country in 2014, with economic development relying on fishing and mining. Fish is crucial for adequate nutrition, but the presence of foodborne hazards in fish is a major concern. This study evaluated the microbiological and biochemical properties of fresh sardines in Mauritania. Samples collected at landing sites generally met quality standards, but a significant proportion of samples from market sites exceeded permissible limits for microbiological parameters. Postharvest contamination was identified as the main health risk, highlighting the need for improvements in cold chain, market hygiene, and food safety training for vendors.

Summary: Plankton seasonality in tropical coastal waters is more apparent due to monsoon-induced changes, but research on the monsoonal variation of microplastics is limited. This study investigated the monsoonal variation of microplastics in water and their ingestion by zooplankton in Sepanggar Bay, Malaysia. Microplastic concentrations were higher during the Southwest monsoon, but ingestion by zooplankton showed no monsoonal difference. Rainfall and salinity were identified as key drivers of microplastic concentrations, while microplastic bioavailability to zooplankton remained consistent regardless of monsoon. The study also found that microplastic ingestion increased up the planktonic food chain, with higher availability of fibers and small-sized microplastics to zooplankton. The distinct changes in microplastic concentration relative to monsoons provide new insights into the seasonal variation of microplastics in tropical coastal ecosystems.

Summary: Phytolyma lata-induced galling is a significant challenge for the regeneration of Milicia species in West Africa. Planting resistant progenies has been identified as a long-term control strategy, but the lack of biomarkers for early detection of resistance has been a limiting factor. The study suggests that polyphenol oxidase (PPO) activity in leaves of Milicia seedlings can serve as a biomarker for resistance to Phytolyma-induced galling.

Summary: This study revealed the widespread occurrence of microplastics in water, sediment, Bagrid Catfish, and Black-chinned Tilapia from the urban riverine system of Densu River in Ghana. The stagnant water system of the Dam promoted the floating of larger-sized microplastics, while the flowing waters of the Delta did not show any selectivity in the deposition of microplastics. The number of microplastics ingested by the two fish species studied was lower compared to marine fish species in coastal Ghana.

Summary: This study demonstrates that glucose can be efficiently produced from cassava peel without chemical or hydrothermal pretreatment. The conversion efficiency was optimized using mixed enzymes and response surface methodology. The empirical models developed provide an efficient tool for glucose recovery and have significance for large-scale industrial production.
