Diversity of freshwater shrimp (decapoda) from bandealit rivers meru betiri national park, East Java, Indonesia

Abstract

Freshwater ecosystems are habitat for macroinvertebrate, fish and reptile groups. One of the macroinvertebrates that can be found in freshwater habitat is shrimp which belongs to the class of Crustaceae, order of Decapoda. This study aims to determine diversity and the abiotic conditions of freshwater shrimp habitat. Determination of sampling locations was done by purposive sampling based on the habitat type of freshwater shrimp and followed by road sampling that takes the straight path from the designated sampling location. The tools used to catch freshwater shrimp are traps and tray nett. The results obtained in the Bandealit river of Meru Betiri National Park were five species of freshwater shrimp consisting of 2 families. The diversity index of freshwater shrimp in the Bandealit river was classified as moderate by the analysis of diversity index. Meru Betiri National Park has ideal abiotic conditions for freshwater shrimp life.

Freshwater Prawns Diversity (Crustacea: Decapoda) in the River Koshi, Eastern Bihar

“…In current survey, low rate of wealth of species was studied in sampling site warning loss of its suitability for nourishing life due to devastation of ecological habitats, increased level of pollution and over exploitation of the species. [8] reported 5 species of freshwater shrimp consisting of 2 families, they also determine diversity and the abiotic conditions of freshwater shrimps habitat in Indonesia and [30] reported relationships between water quality constraints and the development rate of white shrimp (Litopenaeus vannamei) in concentrated ponds. [31], reported the impact of climate change on prawn post larvae fishing in coastal Bangladesh.…”

“…As a matter of facts, large and medium sized freshwater prawns, form economically important group as most of them are harvested from the wild or culture for food as well as aquarium trade [5]. Overall diversity and abundance of freshwater prawns is rapidly declining or under risk category mainly due to competition on from invasive species, change in climate and commercial developmental projects [6,7], quality of water and anthropogenic pollution can be determined by presence of species and their abundance [8,9]. Whereas, [10] reported four species of freshwater prawns in the river Ganga up to Kanpur its availability year around during (1956).…”
