Dear Colleagues:

I am pleased to announce the publication of our research article:

Paudel S, Levesque JC, Saavedra C, Pita C, Pal P. (2016) Characterization
of the artisanal fishing communities in Nepal and potential implications
for the conservation and management of Ganges River Dolphin (*Platanista
gangetica gangetica*) PeerJ 4:e1563 https://doi.org/10.7717/peerj.1563


The Ganges River dolphin (*Platanista gangetica gangetica*) (GRD) is
classified as one of the most endangered of all cetaceans in the world and
the second scarcest freshwater cetacean. The population is estimated to be
less than 2,000 individuals. In Nepal’s Narayani, Sapta Koshi, and Karnali
river systems, survival of GRD continues to be threatened by various
anthropogenic activities, such as dam construction and interactions with
artisanal fisheries. A basic description of the geographic scope,
economics, and types of gear used in these fisheries would help managers
understand the fishery-dolphin interaction conflict and assist with
developing potential solutions. The main goal was to provide new
information on the artisanal fishing communities in Nepal. The specific
objectives were to identify, compile, and investigate the demographics,
economics, fishing characteristics, and perception of fishermen about GRD
conservation in the Narayani, Sapta Koshi, and Karnali rivers so
conservation managers can develop and implement a potential solution to the
GRD-fishery interaction problem in Nepal. Based on 169 interviews, 79% of
Nepalese fishermen indicated fishing was their primary form of income.
Fishermen reported fishing effort was greater in summer than winter;
greatest in the afternoon (14:30 hrs ± 0:27) and during low water level
conditions; and gear was set 4.8 ± 0.2 days/week. Fishermen reported using
eight different types of monofilament nets (gillnets and cast nets). Sixty
percent used gillnets less than 10 m long, and nearly 30% preferred
gillnets between 10 and 100 m long; a few used gillnets longer than 100 m.
Most fishermen reported they believed education, awareness, and changing
occupations were important for GRD conservation, but they indicated that
alternative occupational options were currently limited in Nepal. Nepalese
fishermen acknowledged that fisheries posed a risk to GRD, but they
believed water pollution, and dam/irrigation developments were the greatest
threats.
