難得 holacanthus 仍抱有這份堅定不倦的信念，真真正正的向你致敬！
珍稀頻危的枝牙不採的道理已是說完又說，相信部份懷著真正愛惜頻危魚種的朋友也認同了！
那些老是發起養枝牙採枝牙帖子的有何目的？正所謂 司馬超之心路人皆知 。
憶起 08年在野外第一次與紫身相見，那閃電藍的風采令我贊嘆大自然的美妙及欣賜，心底內卻絕沒有私採之心！其後兩次到訪只能見到空潭一個，枝牙不見了，心底內那種蒼涼失望的感覺非筆墨能形容。從此亦與部份魚友建起了鴻溝，各走各路！
引用 holacanthus 在 樂遙坊的討論資料 :
又揾到D資料, 不過係澳洲嘅, 最近當地政府話要列佢哋嘅枝牙Stiphodon allen做瀕危類喎......但如佢地自己講, 一切可能已太遲, 因S. allen已極罕見, 分分鐘已絕种喎......anyway, 佢地有D野有D講法我覺得可post出嚟大家睇下...

10b. .........Stiphodon spp. are prized by aquarists for their vibrant colours and placid nature. Combined with their rarity, these factors have created a situation where populations may be susceptible to over-collecting. A complete disappearance of Stiphodon sp. 1 has been observed in XXXX Creek in the past 2 years (XXXX, personal observation) and this is presumed to be the result of collections of individuals for private or commercial aquaria use. Individuals have been observed for sale on the world wide web within Australia and collections have been recorded by private aquarists in the journal of the Australian and New Guinea Fish Association “Fishes of Sahul” (e.g. Briggs 2007).
11c. .........Collection of Stiphodon for the aquarium trade poses an impact to Stiphodon species in other parts of the Pacific region (e.g. Yamasaki and Tachihara 2006). Given that the distribution and abundance of Stiphodon spp. appears to be particularly small on continental Australia it is vital to carefully manage the recently discovered populations of this genus here.
大意即係話野採對枝牙係有影響的, 故極有需要監管這些活動.
13. .......Australian Stiphodon spp. have not been translocated (moved from one stream to another) or bred in captivity as yet. The Australian Stiphodon spp. probably has an amphidromous life cycle (Adults breed in freshwater, larvae go to sea and return as juveniles to freshwater) based on congeneric species (Yamasaki and Tachihara 2006, McDowall 2007, Yamasaki et al. 2007) making it difficult to breed and grow-out in captivity. The lack of precedence for captive production of this species is of concern.
枝牙的洄游性令其根本極難在魚缸繁殖.
19. .....The distribution of this genus is highly fragmented. It is certainly possible that small isolated populations exist in remote localities within the Wet Tropics. However, this group of fishes is clearly not widespread or abundant. Furthermore a major risk to the group is that aquarium collectors that locate new populations themselves pose a risk to the species.
牠們分佈零碎, 也不大量, 野採對其是主要威脅之一.
29. ........All wild populations are necessary for the survival of this group.
任何野外族群對整个种群的存活均十分重要.
43b. .........Clearly Stiphodon have been collected from streams of the Wet Tropics for aquaria. Stiphodon have been observed in one aquarium outlet in Cairns and have been collected by private aquarists (based on written articles in the ANGFA journal). Population sizes of Stiphodon are extremely small in the wet-tropics and therefore even small levels of harvesting have the potential to threaten species. Reductions in numbers have been observed in XXXX Creek but are largely anecdotal. The actual impact of this harvesting is currently unknown.
大意為由於族群量小, 細規模採集已可構成危害.
大家都是愛魚之人，何苦一定要把珍稀頻危的帶回家！ |
