This study examines the occurrence, abundance, characteristics, and risk assessment of MPs in commercial tilapia (<i>Oreochromis niloticus</i>) feeds. MP contamination was found in all feed samples, with the highest levels observed in grower feeds (2150 ± 70.71 MPs/kg), followed by starter feeds (1650 ± 70.71 MPs/kg) and finisher feeds (1300 ± 141.42 MPs/kg). Fibers were the dominant morphotype (85%), and polymer analysis using FTIR identified polypropylene (38.74%) and polyethylene (33.61%) as the most common polymers. Additionally, 84.64% of the extracted MPs were in the 100–1500 µm size range, posing significant health risks to tilapia and potential exposure to consumers. The estimated polymer hazard index (PHI) value for the three feed categories was very high, signaling alarming health risks. The mean polymer load index (PLI) values across the feed categories ranged from 4.23 to 8.03, indicating minor contamination. The study attributes the sources of MPs to feed ingredients, packaging materials, and processing machinery. The high PHI value underscores the need for urgent action to mitigate MP pollution in tilapia farming.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10499-025-01877-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431045","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tilapia nursery is carried out in a semi-intensive system in ponds; however, the biofloc technology system (BFT) has productive, environmental, and health advantages. This study aimed to compare the production of Nile tilapia (<i>Oreochromis niloticus</i>) juveniles in two rearing systems during autumn through the evaluation of fish growth performance, environmental, and hematological parameters, as well as production costs. The 46-day experiment was conducted on a pilot scale, with four experimental units per system stocked with fingerlings averaging 1.95 ± 0.32 g. In the semi-intensive system, 25 m³ ponds were used, and each was stocked with 1100 fingerlings (44 fish m⁻³). In the super-intensive system, 4 m³ circular tanks were used, each stocked with 2200 fingerlings (550 fish m⁻³). The production of tilapia juveniles in BFT showed greater stability of water quality parameters throughout rearing in association with higher water temperature owing to the greenhouse. This allowed similar growth between fish in both systems, but with productivity 12.7-fold higher in BFT, while consuming 29.6 times less water. Hematological parameters among fish in the two systems were also similar. Moreover, the BFT system demonstrated a 6.2% reduction in total operating costs compared to the semi-intensive pond system, positioning it as a more cost-effective option for producing Nile tilapia juveniles in subtropical regions. These results highlight the BFT system’s potential as a viable alternative for rural fish farmers.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its sustainability is often jeopardized by disease outbreaks. This study evaluated disease management practices, biosecurity adoption status, and the factors influencing disease occurrence and biosecurity adoption in Bangladesh’s finfish aquaculture sector. Data were collected from 400 farmers across 6 major fish-producing districts through an online survey tool covering farmer demographics, fish culture practices, disease management practices, and adoption of biosecurity measures. Results revealed that most farmers were male (87%), experienced (&gt; 10 years, 53%), literate, full-time (78%) operators, managing small-scale farms (&lt; 0.45 ha), and favored polyculture technique. Disease occurrence ranked among the top two challenges, affecting approximately 70% of the studied farmers. Common disease management practices included water quality management and chemical therapeutics use (91% each), antibiotics use (53%), and other operational modifications. Overall, biosecurity adoption among farmers was approximately 68%, with 56% identified as high adopters. Widely adopted biosecurity practices included regular farm monitoring and having proper feed storage (96% each) while avoiding restocking (14%) was the least adopted. Significant (<i>P</i> &lt; 0.05) regional variations were observed in farmer demographics, fish culture practices, disease occurrences, and biosecurity adoption levels. Significant associations between disease occurrence and biosecurity adoption with several socio-demographic and operational factors emphasized the need for tailored interventions.

In this study, we identified seven <i>CYP3A</i> genes in <i>A. japonicus</i> using gonadal transcriptomic data. These genes exhibited ubiquitous expression across adult tissues, with significantly higher levels in ovarian tissues compared to testes tissues. Protein sequence analysis revealed that the catalytic residues Ala ₃₀₆-Thr ₃₁₀-Cys ₄₃₇, which are critical for aromatase activity, are highly conserved. This suggests that CYP3A proteins may mediate aromatization-like reactions similar to CYP19A in vertebrates. Additionally, dietary administration of the aromatase inhibitor letrozole led to histological changes in the testes and a reduction in the diameter of large oocytes in the ovaries. These findings provide valuable insights into the molecular mechanisms underlying gonadal development in sea cucumbers and lay the groundwork for future research on the artificial induction of sex reversal in echinoderms.</p></div>","PeriodicalId":8122,"journal":{"name":"Aquaculture International","volume":"33 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study explores the use of cheap, readily available, and environmentally friendly sugarcane bagasse and luffa sponge fiber as porous lignocellulosic biomass for biotransforming ammonia in experimental aquaponics water. A 45-day experiment was set up, with <i>Pangasianodon hypophthalmus</i> as the experimental fish in tanks containing aquaponics water. The study consists of a control (CON) and three treatments, viz. BAF (Bagasse), LuF (Luffa fiber), and MixF (Bagasse + Luffa fiber). Weekly spiking of ammonia at different doses was carried out (2, 2.5, 3, 5, and 10 mg L⁻¹). Porous lignocellulose reduced ammonia, resulting in lower stress and better growth through two mechanisms, viz., substrate for the autotrophic nitrifiers to perform nitrification shown by the increase in nitrite with the decrease in ammonia and the assimilation of ammonia by the aerobic heterotrophs using the lignocellulose as a carbon source, which is indicated by the increase in the colony-forming units in terms of biofloc in the water. The result showed the ammonia removal efficiency to be highest in MixF with 67.75% ± 3.26 after 96 h of spiking 10 mg L⁻¹ TAN, followed by BAF and LuF, while the control group was ineffective at 10 mg L⁻¹ TAN. The treatment groups also showed higher fish yield performance and better hematological and serum biochemical parameters as compared to the control group, as plant-assisted bioremediation protects fish against ammonical stress. The study addresses the critical issue of ammonia management in aquaculture by developing an economically sound and sustainable bioremediation model based on the combined effect of biofilm and biofloc.
