Abundance and composition of zooplankton at Sitakunda coast of Chittagong, Bangladesh

Abstract

Correction: Table 1 and Table 2 were omitted in from the PDF of this article. On 29th April 2015 the two tables were included in the PDF and the page numbers were changed from 151-158 to 151-160.Eight groups of zooplankton were found at Sitakunda coast, Chittagong, northeastern part of the Bay of Bengal during January to June 2007. The identified groups were Appendicularia (2.46%), Chaetognatha (2.45%), Cladocera (2.31%), Copepoda (26.05%), Ctenophora (5.86%), Crustacean zooplankton (21.64%), Ichthyoplankton (17.77%) and Meroplankton (21.45%). Abundance of zooplankton varied from 413 to 7730 individuals/m3.Mangrove vegetate area (station- VI) has the highest abundant possibly due to the organic and inorganic matters dissolved in the water while ship breaking area (station- IV) has the lowest abundant. Zooplankton population was significantly (p>0.05) higher in the mangrove vegetate area than the fishermen community area and ship breaking area. The mangrove vegetate area has the highest composition (57.06%) of zooplankton than the fishers community area and ship breaking area (29.77% and 13.16%, respectively). Calanus sp. (12.29%) belonging to Copepods and fish eggs (9.25%) belonging to Ichthyoplankton were the most abundant and Oikopleura albicans (0.66%) from Appendicularia, Metapenaeus brevicornis (0.71%) and Metapenaeus monoceros (0.90%) belonging to Crustacean larvae were the lowest abundant species found at three major investigated area.Res.

Identification of Marine Zooplankton in the Maheshkhali Channel, Cox’s Bazar, Bangladesh

“…Distribution: Most species live in temperate oceanic regions, but some are restricted to north Atlantic Ocean. The species was found in the Sitakunda coast of Chittagong [13], Bakkhali river estuary of Cox's Bazar in Bangladesh [11].…”

“…Distribution: Ctenophores are distributed in all types of marine environments, for example, in coastal waters, estuaries mid oceans, polar regions, etc. In Bangladesh, ctenophora larvae was recorded in the Sitakunda coast [13], Bakkhali river estuary [11] and Northern Bay of Bengal [6,24].…”

“…The dominant groups were copepods, amphipoda, isopoda, crustaceans, ichthyoplankton and meroplankton. Although there are some studies on zooplankton ecology in several coastal areas of Bangladesh [6,11,12,13], the identification of zooplankton in many coastal areas of Bangladesh (which are also important for nursery and breeding ground for fisheries) remain undetermined.…”

Abundance and Biodiversity of Zooplankton in Salimpur Coast, Bangladesh

“…Zooplankton assemblage data were analyzed with the Plymouth Routines in Multivariate Ecological Research (PRIMER) statistical package version 6 (Clarke and Warwick, 06). Diversity of the species assemblage was analyzed by the Shannon-Wiener index (H') [15][16][17][18][19][20][21], species richness was measured by Margalef index (d) and evenness was measured by Pielou's index (J') (Pielou, 1966). The value of the Shannon-Wiener index, Margalef index, and Pielou's index calculated by the following formula: Pielou's Evenness Index (J')…”

Temporal distribution of zooplankton communities in coastal waters of the northern Bay of Bengal, Bangladesh

“…These waterways support aquatic resources (e.g., fishes, shrimps, mangroves, molluscs, and seaweeds) and contribute to national economy. However, in recent decades, about 950 industries (i.e., ship breaking, chemicals, and oil refineries) arose in this coastal area causing air, water, and soil pollution with aquatic ecosystems biodiversity lost (Iqbal et al, 2014;Khan et al, 2015;Sharif et al, 2017;Abdullah Al et al, 2018). Up to now, only a few studies dealt with zooplankton along with environmental parameters, and with their application to water quality bioassessment in the northern Bay of Bengal, Bangladesh (Iqbal et al, 2014;Khan et al, 2015;Abu Hena et al, 2016;Sharif et al, 2017;Abdullah Al et.…”
