A multistage sampling technique selected 300 respondents comprising male and female farmers and extension agents. Data were analyzed using Latent Class Analysis (LCA), Binary Logistic Regression, Z-test analysis, and Exploratory Factor Analysis (EFA). LCA identified four distinct classes of CSA technologies promoted through extension: Crop-Centred Adopters (33.0%), Soil and Water Management Adopters (26.0%), Integrated Resilience Adopters (24.0%), and Comprehensive CSA Adopters (17.0%), with the four-class solution demonstrating optimal fit (BIC = 4,802.14; Entropy = 0.876). Logistic regression revealed that education (B = 0.211, p = 0.002), extension contact frequency (B = 0.361, p &lt; 0.001), mobile phone ownership (B = 1.241, p = 0.001), and gender-sensitive training (B = 1.374, p &lt; 0.001) were the most significant predictors of adoption among female farmers. Z-test analysis confirmed significant gender disparities across all adoption categories, with male farmers recording a higher aggregate mean score (3.54 ±0.69) than female farmers (2.55 ±0.81). EFA identified five constraint dimensions explaining 67.41% of total variance: Gender-Based Socio-Cultural Barriers (Eigenvalue = 4.914; α = 0.894), Institutional and Extension System Deficits (3.881; α = 0.861), Economic and Resource Constraints (3.021; α = 0.843), Technology Access and Literacy Barriers (2.594; α = 0.826), and Climate Information and Risk Perception Gaps (2.318; α = 0.811). These findings confirm that gender roles constitute a fundamental structural barrier to equitable CSA technology adoption, calling for gender-transformative extension programming in Ogun State.</p> Oyeronke A.

This study assessed breeding practices, broodstock sourcing and characteristics, artificial propagation techniques, and health management practices among catfish hatchery operators in Kogi State, Nigeria. A stratified sampling technique was used to select 132 hatchery operators across nine Local Government Areas in the three senatorial districts of the state. Primary data were collected using structured questionnaires and analyzed using descriptive and inferential statistics. The results showed that 56.1% of respondents had received training in fish breeding, with empowerment programmes being the major source of training. Crossbreeding (56.8%) and artificial propagation (65.9%) were the dominant breeding approaches. Most operators sourced broodstock from fish farms (54.5%) and identified them primarily using sex organs (79.6%), with little use of standardized identification methods. Broodstock were generally of moderate size (2-2.5 kg) and relatively young (10-11 months). Milt extraction was predominantly carried out by sacrificing male fish (84.1%), while synthetic hormones such as ovatide (37.9%) and ovulin (34.1%) were widely used for induced spawning. Most hatcheries produced juveniles (49.2%), reflecting a preference for larger seed sizes. Water for hatchery operations was mainly sourced from rivers (44.7%) and boreholes (40.9%), with aeration (64.4%) being the principal water quality management practice. Although over half of the operators monitored water quality daily, the use of filtration systems and diagnostic facilities was limited. Bacterial infections (40.2%) were the most commonly reported diseases, and medication (58.3%) was the predominant health management strategy. The study concludes that while hatchery operators in Kogi State have adopted key artificial propagation techniques, significant gaps exist in broodstock management, genetic improvement, water quality control, and disease prevention. Strengthening technical capacity, promoting structured breeding programmes, improving hatchery infrastructure, and enhancing preventive health management practices are essential for improving fish seed quality and ensuring sustainable aquaculture development.</p> Jamiu Muhammed DAUDA Marinus EGWENOMHE Caleb Ojochegbe OBAJE Mohammed Awwal GALADIMA Comfort SALIFU ##submission.copyrightStatement## https://creativecommons.org/licenses/by-nc-nd/4.0 2026-05-25 2026-05-25 9 4 19 35 10.5281/zenodo.20375378
