“…The fisheries share is more than 71% of the economic value of the Chilika ecosystem (Kumar, ). The lake also supports the economy with earnings of about half a million US$ in foreign exchange through the export of fishes (Mohanty et al., ). Hence, updated information on the fish stocks is of utmost importance for the sustainable management of this ecosystem.…”

Length-weight relationships of six tropical fish species from Chilika Lagoon, India

et al. 2016

Summary The length weight relationships (LWRs) of six tropical fish species from Chilika Lagoon, India were studied. Specimens were caught using a wide range of fishing gear operated in the lagoon from January to December 2014. The fresh specimens were measured for total length and weight, then dissected and the sex confirmed. Previously unavailable in FishBase, the detailed LWRs of Daysciaena albida, Eleutheronema tetradactylum, Etroplus suratensis and Mystus gulio are reported for the first time. Maximum total lengths reported for Nematalosa nasus and Osteogeneiosus militaris in this study are new records for these species. The existence of a differential growth between male and female O. militaris was confirmed, which was not known earlier.

“…A total of 221 species have been collected from the lagoon up to March 2004, comprising 187 species of fish, 18 species of prawn, 14 species of crab and 2 species of lobster (Mohanty et al, 2006;Mohapatra et al, 2007a).

“…This area, approximately 20 km long with an area of 30 km 2 , were surveyed from 29 January to 2 February 2007 and from 24 to 29 February 2008. The width of the Outer channel varied from 300 to 1200 m. Tidal currents introduce seawater on a daily basis through the estuary area, enhancing the biological productivity of the lagoon (Mohanty et al, 2007;Panda et al, 2008;Khan et al, 2011). A wooden boat, usually used for dolphin-watching cruises in this area, was hired for the survey.…”

Abundance estimation of marine mammals requires matching of detection of an animal or a group of animal by two independent means. A multimodal detection model using visual and acoustic cues (surfacing and phonation) that enables abundance estimation of dolphins is proposed. The method does not require a specific time window to match the cues of both means for applying mark-recapture method. The proposed model was evaluated using data obtained in field observations of Ganges River dolphins and Irrawaddy dolphins, as examples of dispersed and condensed distributions of animals, respectively. The acoustic detection probability was approximately 80%, 20% higher than that of visual detection for both species, regardless of the distribution of the animals in present study sites. The abundance estimates of Ganges River dolphins and Irrawaddy dolphins fairly agreed with the numbers reported in previous monitoring studies. The single animal detection probability was smaller than that of larger cluster size, as predicted by the model and confirmed by field data. However, dense groups of Irrawaddy dolphins showed difference in cluster sizes observed by visual and acoustic methods. Lower detection probability of single clusters of this species seemed to be caused by the clumped distribution of this species.
