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. Findings revealed that 61.1% of respondents consume fish without processing, with only 20.8% using salting and 18.1% practicing drying. The drying process notably affected texture, smell, and color. Most respondents (91.7%) preferred fresh fish due to financial constraints, lack of awareness, and market access. Species preference (40.3%), quality (33.3%), and market demand (23.6%) influenced pricing. Transportation is often done using donkey-back loads that could increase the risk of fish contamination. Although 50% of respondents stored harvested fish for one day without treatment, among these, 88.9% reported no spoilage within a day. Handling materials varied, with metal containers (33.3%) being the most common. Fish is primarily consumed as stew (39.4%) in the study area. Among these, almost all (91.9%) enjoy eating fish. However, it is often viewed as food for children and for the poor by many of them (60.6%). Despite concerns over fish bones and odors of the fish, 80.6% reported no health issues related to consumption. Most respondents (90.3%) discarded spoiled fish due to a lack of training in fish harvesting and preservation. The study indicates that postharvest losses are minimal due to effective harvesting methods, with immediate consumption practices prevalent in the community.

Introduction: Heavy metal pollution threatens the biodiversity and ecological equilibrium of the Nile River. This study investigates the impact of heavy metal pollution on aquatic animals such as Nile tilapia (Oreochromis niloticus) in the Damietta branch of the River Nile and El-Rayah El-Tawfeeky canal in Benha City in Egypt.

Methods: Fish and water samples were collected from the Damietta branch and El-Rayah El-Tawfeeky during the fall of 2022.

Dietary quality, anaemia prevalence and their associated factors among rural school- going adolescents in Acholi sub -region of Uganda.

Background: Globally, iron deficiency anaemia is a widespread public health problem affecting vulnerable populations including adolescents. However, over the years, the Uganda Demographic Health Surveys mostly report the status of anaemia for women of reproductive age (15-49 years) and children up to 5 years, leaving out the focus on adolescents. Moreover, high prevalence of anaemia among children below five years could suggest that anaemia still persists at adolescence.

Identification of the arachidonic acid 5-lipoxygenase and its function in the immunity of Apostichopus japonicus.

A number of studies have been demonstrated that arachidonate 5-lipoxygenase (ALOX-5) plays a role in regulating a range of physiological and pathological processes through the catalysis of leukotriene formation from arachidonic acid (ARA). The coding sequence of ALOX-5 from Apostichopus japonicus (Aj-ALOX-5) was successfully amplified, resulting in a 2028 bp ORF sequence that encodes 674 amino acids. A comparison of the amino acid sequence with those of other 5-lipoxygenases revealed that Aj-ALOX-5 has the N-terminal "PLAT domain" and C-terminal "lipoxygenase structural domain" characteristic of this enzyme family.

This study investigated the effects of bamboo shoot extract (Bambusa vulgaris) as a feed additive on the health profiles and infection resistance of Nile tilapia (Oreochromis niloticus) against Pseudomonas putida. Bamboo shoot extract was added at levels of 0 g, 40 g, and 60 g per 1000 g of diet over a 60-day period. The fish were then challenged with a pathogenic P.

N6-methyladenosine (m6A) is the most prevalent RNA modification and a multifaceted regulator capable of affecting various aspects of mRNA metabolism, thereby playing important roles in numerous physiological processes. However, it is still unknown whether, when, and to what extent m6A modulation are implicated in the immune response of an economically important aquaculture fish, half-smooth tongue sole (Cynoglossus semilaevis). Herein, we systematically profiled and characterized the m6A epitranscriptome and transcriptome in C.
