Modelled from regional ecology — no survey or occurrence data for this water yet.
- Both counties it runs through publish the same rule: 壶源江（壶源溪）is closed 1 March – 30 June to every method EXCEPT 娱乐性游钓 — recreational angling is explicitly exempt, so this water is effectively fishable year-round
- Zhejiang's own guidance adds one rod, one line, no more than two hook points, and names its no-angling zones as cross-river bridges and Grade 1 drinking-water source protection areas
- No germplasm reserve or water-source designation was found on this stream, but confirm locally
⭐ None of these fish is protected, which is what makes this water unusual in China. 马口 (*Opsariichthys bidens*) is now **scored** — the first Asian cyprinid with an engine profile, riding the flow-cyprinid lane on aquaculture-derived thermal bands (ideal 20–26°C). 溪石斑 (光唇鱼, *Acrossocheilus*), 宽鳍鱲 and 长鳍鱲 (*Zacco*) and the occasional 鳜鱼 (mandarin fish) remain prose-only: they have no profile of their own, and borrowing makou's — let alone the European `barbel` curve — would be the false precision this pack refuses. / ⭐ 此处鱼种均非保护物种，这在中国颇为难得。马口（*Opsariichthys bidens*）现已纳入计分——它是首个具备引擎模型的亚洲鲤科鱼类，使用流水鲤科通道与源自养殖文献的温度区间（最适20–26℃）。溪石斑（光唇鱼）、宽鳍鱲、长鳍鱲及偶见的鳜鱼仍仅作文字说明：它们没有各自的模型，若套用马口的模型（更遑论欧洲鲃鱼的温度曲线），正是本册所拒绝的伪精确。
