This study was carried out in Bogibeel, a stretch of river Brahmaputra from January 2015 to December 2016. A total, 40 species belonging to 16 families have been recorded from six different fish landing zone during the study period. It has been found that the fish diversity of these hotspots faces serious threats which would lead to a catastrophic loss of our biodiversity. In this work an attempt has been done to inventorize the fish community dwelling in the wetland, analysis of the anthropogenic threats and the prospect of aqua ecotourism is a mega conservatory tool to maintain ecological integrity of these aqua landscapes as well as the dwindling fish fauna.
Recent assessments depicts that conservation of freshwater ecosystems has been in focus [1,2] since along with their terrestrial counterparts the aquatic ecosystems are increasing harnessed for providing renewable resources along with poor planning. With increasing change in global climate coupled with anthropogenic activities has drastically affected aquatic ecology as well as the fish community dwelling therein and wetlands are no exceptions to it. Evaluations suggest that worldwide 20% of all freshwater fish species are extinct, endangered or vulnerable .
Ecotourism is an emerging arena and aqua ecotourism is a much recent and debatable term. Study suggests that ecotourism achieved the attributes of generating economic benefits to that local mass as well conservation of nature. Aquarium fish keeping has evolved as an indispensible part of interior decoration in the 21st century. In the work, an attempt has been made to prioritize among the fishes of this region the potential ornamental fishes along with their endemic status and status of threat and prospect of aqua ecotourism and recreational fisheries as conservatory mega tool.
Study area: Bogibeel (Coordination: 27.41/23// N, 94.75/65// E), a permanent stretch of river Brahmaputra
and adjoining wetland. It has a meso-thermal climate. The temperature ranges between 10.6°C to 32°C.
Sampling: Continuous monitoring and sampling is done so that rare indigenous fishes in different seasons are not missed for a period of one year from June 2015 to July, 2016. Fishes are collected randomly to cover all possible habitat types and identified and classified of following Talwar & Jhingran .
During the investigation 40 species belonging to 17 families have been recorded from the six different fish landing zones. Emergence of high number exotic species like Ctenopharyngodon idella, Cyprinuscarpio, and Hypophthalmichthysmolitrix may be threat for indigenous species in near future. Out of 40 species following species Chitala chitala,Anabas testudineus, Channa marulius, Channa striatus,Mystus cavasius, Mystus tengara, Sperata aor, Clarias magur, Heteropneustes fossilis, Ompok bimaculatus, Ompok pabda, Ompok pabo and Monopterus cuchia have high market value as food fish. During the study it was observed that highly market demanded fishes like Chitala chitala, Ompok bimaculatus, Ompok pabda and Ompok pabo have coming into IUCN 2014.3Near threatened category. Due to this reason; these four species may be totally extinct from this wetland in near future. And species like Lepidocephalichthys guntea, Acanthocobitis botia, Mystus Cavasius, Chanda nama, Trichogaster fasciata, Trichogaster lalia, Xenentodon cancila,
Esomus dandricus, Barilius barila, Nandus nandus, Channa
aurantimaculata, Macrognathus pancalus, Badis badis, Badis
badis havehigh ornamental value around the globe. And it should
also be accounted that some of species Sperata aor, Badis badis,
Macrognathus pancalus and Ompok pabda were found to be
very rare during investigation and therefore it is necessary to
conserve those species in the studied wetland[5,6].
Aqua ecotourism is a much recent arena which amalgamates
conservation along with employment generation. The money
generating attributes will be from entry fees, angle hiring and
bait, the restaurants as well as artificial breeding which have
manifold advantages like conservation state can be achieved
and helps in employment generation. Moreover, unauthorized
fishing as well as other detrimental activities will be banned.
