<p>Un manejo pesquero eficiente es fundamental para que las pesquerías artesanales puedan continuar proveyendo alimento y sustento los hogares, particularmente en países vía de desarrollo, donde otras opciones a menudo son limitadas. Estudios sobre la dinámica poblacional especies objetivo son, por lo tanto, imperativos mantener beneficios sociedades. Esto también válido recursos del Lago Koka (Etiopia) hasta ahora se sabe muy poco parámetros poblacionales vitales el estatus como...
Abstract The study explores the impacts of varying gillnet mesh size and fishing level on yield per recruit ( Y/R ), escapement spawning stock ESS ) mega‐spawners MS three widely distributed freshwater fishery target species. is maximised when optimal length capture L cap above maturity 50 ). However, unimodal shape selectivity results in lower to with both smaller larger sizes. Under conditions moderate exploitation, fraction was significantly if small meshed gillnets were used. This due...
Anthropogenic activities continue to pose the greatest challenges freshwater ecosystems. Therefore, long-term monitoring is essential for management and conservation of these resources. Monitoring programs bodies often use a range indicators, including biological elements such as fish. Existing European standard provides depth-stratified gillnet sampling approach mainly in benthic habitats at deepest part lakes account uneven distribution However, commonly used CEN (European Committee...
This study aims to assess hand hygiene compliance and associated factors among healthcare providers in Dessie referral hospital (Ethiopia) using the gold standard WHO's observational checklist self-administered questionnaire. Hand practices of 230 from ten wards were observed over 24 hours period. The required numbers sample proportionally allocated different professions wards. overall was only 17.6%. training , availability functional sink knowledge about attitude towards water soap...
Abstract Global inland freshwater fisheries support livelihoods for several million people. These important resources, however, are suffering from excessive overfishing as a result of increasing fishing pressures attributable to an increased human population and subsequent demand food economic livelihoods. To this end, very little is known about the vital parameters stock status Nile tilapia ( Oreochromis niloticus ) in Lake Chamo Ethiopia. Thus, present study focused on determining...
The Afar region is characterized by an arid and semi-arid climate with erratic rainfall prone to frequent droughts despite being endowed fresh saline water bodies along the Awash River Basin. Lake Hertale one of those located in middle Valley. lake's fishery presumed not have been exploited before. study attempted describe some physico-chemical parameters, fish species composition, estimate production potential which are relevant develop a lake prospect contributing food nutrition security....
The study was conducted to investigate the breeding season, sex ratio, size at maturation, fecundity and condition factor of African catfish Clarias gariepinus in Lake Koka. A total 754 fish specimens were collected from October 2020 August 2021. Total length weight measured sexes identified gonad maturity levels recorded. ratio different classes similar that a hypothetical 1:1 ratio. first (L50) 51.8 cm length. mean Fulton’s female ranged 0.65 ± 0.05 – 0.71 0.14, while males 0.62 0.04 0.7...
Nile tilapia, Oreochromis niloticus, is a widely distributed and economically most import fish species in Ethiopia. Effective management essential to sustain their fisheries the benefits for local communities. However, little known about population dynamics of tilapia stock Lake Langeno. Vital parameters its were determined using length frequency data collected from 5,949 specimens ranging 8.5 35.7 cm total (tl). These August 2017to July 2018. The elefan I routine FiSAT software.

Ethiopia has a large biomass of water hyacinth (<i>Eichhorniacrassipes</i>) in Lake Koka and LakeTana during the summer season. Local community doesn’t use this hyacinth. So activity is designed to produce biodiesel from determine its quality parameters. This should be based on concept renewable energy discard lake. The Specific gravity (g/ml), Acid value (mgKOH/g), Water content (mg/g), kinematic Viscosity (mm<sup>2</sup>/sec) ash% (w/v) were 0.912, 0.4, 0.004, 2.7 0.001 respectively....
The purpose of this study was to assess the effect emodin on biochemical variables, antioxidant activity, heat shock protein gene expression and prawn intestinal morphology (Macrobrachium rosenbergii). Three feeds containing 0 mg kg–1 (T1, control group), 25 (T2) 50 (T3) were formulated fed for eight weeks. Alanine aminotransferase, total cholesterol triglyceride contents significantly lowered although glucose tended increase following remedy. Superoxide dismutase variables in haemolymph...
Knowledge of fish reproductive biology is very essential for proper resource management. Thus, the study aimed to investigate breeding season, sex ratio, size at maturation, fecundity, and condition factor Clarias gariepinus (B.) in Lake Koka. Fish specimens were collected from October 2020 August 2021 six sampling occasions covering pre-rainy, rainy dry seasons. From specimens, total length weight measured nearest 0.1 cm 1 g, respectively. Moreover, sexes identified gonad maturity levels...
