Aporocotylids (Trematoda: Digenea), also known as fish blood flukes infect the circulatory system of fish leading to serious health problems and mortality. Aporocotylids are a particular concern for farmed fish as infection intensity can increase within the farming environment and lead to mortalities. In the context of managing these infections, one of the most crucial aspects to consider is the host response of the infected fish against these blood flukes. Understanding the response is essential to improving current treatment strategies that are largely based on the use of anthelmintic praziquantel to manage infections in aquaculture. This review focuses on the current knowledge of farmed fish host responses against the different life stages of aporocotylids. New treatment strategies that are able to provide protection against reinfections should be a long-term goal and is not possible without understanding the fish response to infection and the interactions between host and parasite.

Freshwater environments are biodiversity hotspots under multiple pressures, including pesticide exposure. S-metolachlor, a widely used herbicide, can induce genotoxic, cytotoxic and physiological effects in captive fish, but we have a limited understanding of the effects of exposure to S-metolachlor in free-living vertebrates. We carried out an original field experiment using integrative approaches across biological levels and temporal scales.

We analysed the chromosomal structures of two wheat-Thinopyrum intermedium addition lines Z4 and Z5 and resolved the linkage relationship between the leaf rust and stripe rust resistance genes in Z4. Wheat addition lines Z4 and Z5 carrying rust resistance genes from Thinopyrum intermedium (JJJJStSt, 2n = 6x = 42) together with three wheat lines involved in the production of these addition lines were analysed by rust response, 90K SNP genotyping, and molecular cytogenetic analysis. Seedling leaf rust (LR) responses to five diverse pathotypes indicated that the LR resistance gene(s) was located in translocation chromosome T3DS-3AS.

This study assessed the factors contributing to postharvest loss of fish around the Fincha'a, Amarti, and Nashe reservoirs in Horro Guduru Wollega, Oromia, Western Ethiopia, using semi-structured questionnaires from January, 2022 GC onward. The aim of the finding was to know the fish handling and post-harvest preservation of fish around the reservoirs. In the study area, 320 respondents were selected using a random sampling system.

Electronic address:
Composite polymers are promising solution to structural setbacks of starch and alginate-based films due to their hydrophilic attributes. Hence, this study aimed to investigate young coconut jelly powder (CJP), an under-utilized by-waste, as a filler using the casting method to develop a novel biocomposite from increments of CJP (1-3 %) to a blended resin of arrowroot starch, sodium alginate, and glycerol. Moreover, the films were characterized by physicomechanical (visual aspect, thickness, color, moisture content, tensile strength, and elongation at break); surface microstructure; water barrier (water vapor permeability, water solubility, and water activities); thermal, crystallinity, and functional group properties; soil, river water, and seawater biodegradability; and coating application in cherry tomato.

For a long time, grass carp culture in China has been severely affected by Grass Carp hemorrhagic disease caused by Grass Carp Reovirus (GCRV). At present, vaccines have been widely used for protecting aquatic organisms against infectious diseases, among which oral immunization with Lactobacillus casei is safe and highly effective. This vaccination route has the advantages of easy administration and noninvasive delivery.
