Occurrence of nano/microplastics from wild and farmed edible species. Potential effects of exposure on human health.

The occurrence of nano/microplastics (N/MPs) has become a global concern due to their risk on the aquatic environment, food webs and ecosystems, thus, potentially affecting human health. This chapter focuses on the most recent evidence about the occurrence of N/MPs in the most consumed wild and farmed edible species, the occurrence of N/MPs in humans, the potential impact of N/MPs on human health as well as future research recommendations for assessing N/MPs in wild and farmed edible species. Additionally, the N/MP particles in human biological samples, which include the standardization of methods for collection, characterization, and analysis of N/MPs that might allow evaluating the potential risk of the intake of N/MPs in human health, are discussed.

Fishmeal Dietary Replacement Up to 50%: A Comparative Study of Two Insect Meals for Rainbow Trout ().

The demand of optimal protein for human consumption is growing. The Food and Agriculture Organization (FAO) has highlighted aquaculture as one of the most promising alternatives for this protein supply gap due to the high efficiency of fish growth. However, aquaculture has been facing its own sustainability problem, because its high demand for protein has been traditionally satisfied with the use of fishmeal (FM) as the main source.

Molecular and morphological evidence for three species of Diplostomum (Digenea: Diplostomidae), parasites of fishes and fish-eating birds in Spain.

Background: Recent molecular studies have revealed high species diversity of Diplostomum in central and northern Europe. However, our knowledge of the distribution of Diplostomum spp. in the southern distributional range in Europe of the snail intermediate hosts (Lymnaea stagnalis and Radix spp.

Histological alterations on the structure of the excretory renal system in tench (Tinca tinca) after exposure to 17-alpha-ethynylestradiol.

This study describes the effects of 17-alpha-ethynylestradiol (EE2) on the structure of the excretory system of the kidney in tench. Adult male tench were exposed to sub-lethal doses of EE2 (50, 100 and 500 μg/kg b.w.

Histological alterations in the structure of the testis in tench (Tinca tinca) after exposure to 17 alpha-ethynylestradiol.

Environmental pollution with synthetic estrogens may pose a serious threat to reproduction of aquatic wildlife species. The current study describes the effects of 17α-ethynylestradiol (EE2 ) on the structure of the testis in tench (Tinca tinca). Adult male tench were exposed to sublethal doses of EE2 (50, 100, and 500 μg/Kg t.
