成体专用高蛋白颗粒料Adult high-protein pellets
主要原料：鱼粉（粗蛋白 ≥ 60%）、虾粉、藻类粉（螺旋藻）、维生素预混料、矿物质微量元素。Main ingredients: fish meal (crude protein ≥ 60%), shrimp powder, algae (Spirulina), vitamin premix, mineral trace elements.
- 漂浮型：颗粒直径 2–3 mm，投入水中漂浮于水面 10–15 分钟后软化。适合观察采食行为，减少水质污染。建议每次投喂后 30 分钟内捞出残饵。Floating type: 2–3 mm pellets, float on water surface for 10–15 min before softening. Suitable for observing feeding behaviour; reduces water quality deterioration. Remove uneaten pellets within 30 min.
- 缓沉型：颗粒缓慢下沉，模拟爪蟾底栖摄食习惯，适合不主动上浮采食的个体（常见于应激或疾病恢复期）。Slow-sinking type: pellets sink slowly, simulating the benthic feeding habit of Xenopus — suitable for individuals that do not surface to feed (common during stress or disease recovery).
投喂频率：性成熟成体每周 2 次，每次投喂量约为体重的 2–3%；卵母细胞供体雌蛙术前 2 周可增至每周 3 次。Feeding frequency: mature adults 2×/week at 2–3% body weight per feeding; increase to 3×/week for 2 weeks before oocyte harvest in donor females.
蝌蚪专用超细微粒悬浮料Tadpole micro-suspension feed
主要原料：鱼粉（细磨，粗蛋白 ≥ 55%）、藻类粉、磷酸钙、必需氨基酸复合物。颗粒直径 < 50 µm，可在水中形成均匀悬浮，适合蝌蚪滤食性摄食方式。无激素添加，钙磷比例优化（1.2:1），促进骨骼发育与健康变态。Main ingredients: finely milled fish meal (crude protein ≥ 55%), algae, calcium phosphate, essential amino acid complex. Particle diameter <50 µm forms homogeneous suspension suitable for filter-feeding tadpoles. Hormone-free; optimized calcium:phosphorus ratio (1.2:1) to support skeletal development and healthy metamorphosis.
- NF 46 期前蝌蚪：每日投喂 1–2 次，少量多次，避免残余料积累导致水质恶化。Tadpoles before NF 46: feed 1–2×/day in small amounts, avoid accumulation of residual feed.
- NF 46 期后（四肢发育期）：逐步减少微粒料，可引入细碎颗粒料过渡。After NF 46 (limb development): gradually reduce micro feed and transition to finely crushed pellets.
补充活体 / 冻干饵料Supplementary live / freeze-dried feeds
- 冻干红虫（摇蚊幼虫）：高蛋白高适口性，可提升食欲低下个体的采食量；建议每 1–2 周补充一次，不宜单独作为主食（脂肪含量偏高）。Freeze-dried bloodworms (Chironomus larvae): high protein, highly palatable, improves intake in appetite-suppressed individuals; supplement every 1–2 weeks, not as sole diet (higher fat content).
- 冻干水蚤：富含 ω-3 不饱和脂肪酸，适合蝌蚪补充饲喂；蛋白质含量约 50%，脂肪较低，适口性佳。Freeze-dried Daphnia: rich in ω-3 fatty acids, suitable tadpole supplement; ~50% protein, low fat, good palatability.
水质与投喂管理建议Water quality & feeding management tips
- 投喂后 30–60 分钟换水 20–30%，防止氨氮积累；硝酸盐浓度控制在 < 40 ppm。Change 20–30% of water 30–60 min after feeding to prevent ammonia build-up; keep nitrate below 40 ppm.
- 成体养殖最适水温 18–22℃，使用经去氯处理的自来水或纯净水（不宜用蒸馏水）；添加 NaCl 至约 0.6 g/L 有助于维持渗透压平衡。Adult optimal water temperature 18–22 °C; use dechlorinated tap water or purified water (not distilled); adding NaCl to ~0.6 g/L helps maintain osmotic balance.
- 蝌蚪对余氯敏感，换水需充分曝气或使用水质处理剂中和氯胺。Tadpoles are sensitive to residual chlorine — aerate water fully or use a water conditioner to neutralise chloramine.
- 记录每次投喂量与水质数据，便于发现健康问题与实验数据关联分析。Record feeding amounts and water quality data to correlate with health issues and experimental outcomes.
