Published: Sept. 27, 2022

Most disposable plastic products are degraded slowly in the natural environment and continually turned to microplastics (MPs) nanoplastics (NPs), posing additional environmental hazards. The toxicological assessment of MPs for marine organisms mammals has been reported. Thus, there is an urgent need be aware harm human immune system more studies about immunological assessments. This review focuses on how produced they may interact with our body, particularly their responses immunotoxicity. can taken up by cells, thus disrupting intracellular signaling pathways, altering homeostasis finally causing damage tissues organs. generation reactive oxygen species mainly mechanisms after MP exposure, which further induce production danger-associated molecular patterns (DAMPs) associate processes toll-like receptors (TLRs) disruption, cytokine production, inflammatory cells. effectively cell membranes or proteins form a protein-corona, combine external pollutants, chemicals, pathogens greater toxicity strong adverse effects. A comprehensive research immunotoxicity effects MPs, including various chemical compositions, shapes, sizes, combined exposure concentrations, worth studied. Therefore, it urgently needed elucidate hazards risks humans that exposed MPs.

Welfare in Farmed Decapod Crustaceans, With Particular Reference to Penaeus vannamei

Frontiers in Marine Science, Journal Year: 2022, Volume and Issue: 9

Published: May 6, 2022

The farming of decapod crustaceans is a key economic driver in many countries, with production reaching around 9.4 million tonnes (USD 69.3 billion) 2018. These efforts are currently dominated by the Pacific whiteleg shrimp, Penaeus vannamei , which translates into approximately 167 billion farmed P. being harvested annually. Further growth expected future and hence need for more research its health welfare required. Herein, from an extensive survey available literature, we scrutinise practices challenges associated animal-centric perspective (1), propose potential indicators (2) critically review current scientific evidence sentience penaeid shrimp among other commercially important decapods (3), since it plausible that near not only largest, but fact all will receive protection. This highlights despite wide knowledge on crustacean stress physiology immunology as well disease control, still little known about some parameters related to five dimensions. We recommend further should focus developing systematic integrated assessment encompassing different aspects life cycle up slaughter. Furthermore, direct indirect species-specific operational be developed farmed, similar ones suggested this .

This study investigated impacts of microplastics from disposable polypropylene medical masks on woodlice Porcellio scaber, mealworm larvae Tenebrio molitor and enchytraeids Enchytraeus crypticus. Effects survival, reproduction, immune parameters energy-related traits were assessed after 21 days exposure in soil. Microplastics obtained each mask layer separately differed size shape (inner frontal layer: 45.1 ± 21.5 µm, fibers; middle filtering 55.6 28.5 fragments; outer 42.0 17.8 fibers) composition additives.

Multipathogen infections and multifactorial pathogenesis involved in noble pen shell (Pinna nobilis) mass mortality events: Background and current pathologic approaches

Veterinary Pathology, Journal Year: 2023, Volume and Issue: 60(5), P. 560 - 577

Published: July 17, 2023

Disease outbreaks in several ecologically or commercially important invertebrate marine species have been reported recent years all over the world. Mass mortality events (MMEs) affected noble pen shell ( Pinna nobilis), causing its near extinction. Our knowledge of dynamics diseases affecting this is still unclear. Early studies investigating causative etiological agent focused on a novel protozoan parasite, Haplosporidium pinnae, although further investigations suggested that concurrent polymicrobial infections could pivotal some MMEs, even absence H. pinnae. Indeed, moribund specimens collected during MMEs Italy, Greece, and Spain demonstrated presence bacteria from within Mycobacterium simiae complex and, cases, similar to Vibrio mediterranei. The diagnostic processes used for investigation are not standardized require expertise veterinary para-veterinary pathologists, who simultaneously evaluate variety factors, clinical signs environmental conditions.

While most crab production for human consumption worldwide comes from capture fisheries, there is increasing of selected species using aquaculture-based methods. This both the purpose stock replacement and direct yield consumption.

Gradually, concern for the welfare of aquatic invertebrates produced on a commercial/industrial scale is crossing boundaries science and becoming demand other societal actors. The objective this paper to propose protocols assessing Penaeus vannamei during stages reproduction, larval rearing, transport, growing-out in earthen ponds discuss, based literature review, processes perspectives associated with development application on-farm shrimp protocols. Protocols were developed four five domains animal welfare: nutrition, environment, health, behaviour. indicators related psychology domain not considered separate category, proposed indirectly assessed domain. For each indicator, corresponding reference values defined field experience, apart from three possible scores experience continuum positive (score 1) very negative 3). It likely that non-invasive methods measuring farmed welfare, such as those here, will become standard tool farms laboratories it increasingly challenging produce without considering their throughout production cycle.

Annals of the New York Academy of Sciences, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 9, 2024

Abstract Agriculture is a vital industry in New York State, which ranks among the top‐producing states for dairy, fruits, and several other commodities. As agriculture depends on weather specific climatic conditions, this sector faces extraordinary challenges as York's climate changes. This chapter explores many impacts of changing agriculture, ways these interact with that farmers farmworkers face, opportunities to adapt build resilience.
