INFORMATION ABOUT BIOTOPE
关于生物群落的信息
Description of the area surrounding the biotope: The Negro River is the largest tributary of the left bank of the Amazon River in the Amazon, South America. It is the longest river of black water in the world, and the second largest in volume of water – behind only the Amazon, which helps to form. It has its origin between the Orinoco and Amazon basins. Connects with Orinoco through the Cassiquiare channel. In Colombia, where it has its source, it is called the Guainia River. Its main tributaries are the Rio Branco and the Vaupés River. It disputes being the beginning of the Orinoco River along with the Guaviare River. Drains the eastern Andes in Colombia. After passing through Manaus, it joins the Solimões River and, from that union, the latter becomes the Amazon River.
生物群落周边区域描述：内格罗河是南美洲亚马逊河流域左岸最大的支流。它是世界上最长的黑水河，水量位居第二，仅次于其汇入的亚马逊河。该河发源于奥里诺科河与亚马逊河流域之间，通过卡西基亚雷水道与奥里诺科河相连。在发源地哥伦比亚境内，它被称为瓜伊尼亚河。其主要支流包括布朗库河和沃佩斯河。它与瓜维亚雷河共同被视为奥里诺科河的源头之一，并排除了安第斯山脉东段在哥伦比亚境内的排水。流经马瑙斯后，内格罗河与索利蒙伊斯河汇合，自此以下河段称为亚马逊河。
Description of the underwater landscape of the biotope: Blackwater river but with crystal clear water, with large amount of branches and leaves deposited in the background, the substrate and fine sand mixed with forest litter
生物群落水底景观描述：这是一条黑水河，但水质清澈透明；河底沉积着大量树枝与落叶，基质为细沙并与森林腐殖质混合。
Description of the parameters of the habitat: Black water is extremely poor in mineral salts, nutrients and electrolytes due to poor movement and soft relief of its source regions, Guiana and Central Brazil Shields or in tertiary sediments, where erosion processes they are low intensity and reduced by the forest cover where the water from precipitation penetrates the soil covered by vegetation and carries with it various organic substances. Humic substances are composed of humic and fluvic acids and originate during the process of decomposition of plant residues. The low ion content plus the presence of humic substances give black waters an acid character with pH values between 4.8 and 5.1. The large amount of humic substances and dissolved organic carbon (DOC) (10 to 14 mgC.L -1) from decomposition of organic material is largely responsible for the transparent red / brown coloration of water.
栖息地参数描述：黑水因源头地区（圭亚那地盾和巴西中部地盾）或第三纪沉积物中水流缓慢、地势平缓，矿物质盐类、营养物质和电解质含量极低；在这些区域，侵蚀作用强度较低，且被森林覆盖所减弱。降水渗入植被覆盖的土壤后，携带多种有机物质形成黑水。腐殖质由腐殖酸和黄腐酸组成，源于植物残体的分解过程。低离子含量与腐殖质的存在使黑水呈酸性，pH 值介于 4.8 至 5.1 之间。大量腐殖质及来自有机物质分解的溶解性有机碳（DOC）（10 至 14 mgC·L⁻¹）是水体呈现透明红褐色的主要原因。

Threats to the ecology: The Amount Raised distributed among families practicing ornamental fishing means family support with lawful activity and strong appeal preservationist, because without this resource, such for other activities intended to feed their families, such as sport fishing, acting as guides and / or fishing capturing turtles illegally, hunting animals logging and clearing wood that can cause environmental degradation, as has been the case with the gold mining and logging. The ornamental fish of the municipalities of Barcelos and Santa Isabel do Rio Negro, in Amazonas, have obtained from the National Institute of Industrial Property (INPI) an unprecedented certification in the world: a kind of “green seal” with Indication of Geographic Origin, granted by the first once to a living organism.
生态面临的威胁：向从事观赏鱼捕捞的家庭分配收益，意味着通过合法活动为家庭提供生计支持，并具有强烈的保护主义吸引力；因为若缺乏这一资源，这些家庭将转向其他谋生方式，例如运动钓鱼、担任向导，或非法捕龟、猎杀动物、砍伐林木和清理林地，从而导致环境退化——正如采金和伐木业已造成的后果那样。巴西亚马孙州巴塞卢斯市和圣伊莎贝尔杜里奥内格罗市的观赏鱼，已从巴西国家工业产权局（INPI）获得一项全球前所未有的认证：一种带有地理标志的“绿色印章”，这也是首次授予活体生物的此类认证。
