“…The abundance of polychaetes and gastropods was higher in the stations I due to higher input of nutrients from the sediments, the habitat and environmental condition. Generally, relatively soft surface and high detritus or organic carbon (>3%) in these stations may cause for high food diversity hence supports greater benthic organisms (Arshad et al, 2011;Aura et al, 2011). This result mirrored the findings of other studies in which polychaetes, bivalves, crustaceans were the most abundant group in the Bakkhali Channel system, Cox's Bazar (Abu Hena etal., 2012).These species are common in the coastal seagrass and mangrove habitats.…”

Macrobenthos always play a significant role in the food web of any coastal environment. It also uses as a good aquatic ecosystem health module indicators. The abundance and distributions of macrobenthos in Rezukhal, Cox's Bazar were conducted in relation to hydrological parameters. Samples were collected monthly during June-2015 to May-2016 from three separate stations use different scientific instruments at Rezukhal estuary. A total of 7662 individuals of macrobenthos were counted in total of III stations. Macrobenthos were comprised of six major groups namely Polychaeta (52.22-91.57%), crustacean (3.79-8.09%), Bivalvia (1.05-2.27%), Nemertia (0.79-1.60%), Sipuncula(0-8.55%) and Gastropoda (1.36-31.92%). Total number of macrobenthos was higher at station I (4197 individuals m-2) and lower at station II (1186 individuals m-2) among three stations. The study revealed that highest no. of Macrobenthos were found in Post monsoon period about 3146 individuals m-2 and lowest in Premonsoon period about 1995 individuals m.-2 The average soil and water P H were found in monsoon (5.87&7.45), Post monsoon (5.97&7.28), Premonsoon (6.03&7.33) respectively. The average salinity was found in monsoon (11.92ppt), Post monsoon (25.91ppt), Premonsoon (28.75ppt) respectively. The average spring tide and neap tide level were found in monsoon (15&3.04 ft), Post monsoon (12.67&1.36 ft), Premonsoon (11.28&1.16 ft) respectively. The average soil and water temperature were found in monsoon (28.67&27.67 o C), Post monsoon (29.41&28.5 o C), Premonsoon (29.42&29.83 o C) respectively. Soil moisture ranged was from 26.36-35.07%. The highest organic carbon and organic matter concentration was observed at station I (2.58%-4.3%) and lowest at station II (1.59%-2.96%) respevtively. Maximum fraction of sand by weight was found at stations III (81.60%) and II (76.78%). While the highest fraction of clay (22.58%) and silt (11.20%) was recorded in stations I. It was observed that benthic organism's abundance and distribution pattern were influenced with clay and silt fraction of the sediments as well as hydrological factors.

“…The variation among the stations could also probably be due to higher input of nutrients from the sediments. Generally, relatively soft surface and high detritus or organic matter may cause for high food diversity hence supports greater abundance of benthic organisms [25][26]23].

The present research was conducted to evaluate the monthly variations of macro-zoobenthos of three ponds (pond 1, bottom soil is loam; pond 2, bottom soil is sandy loam; pond 3, bottom soil is silty clay loam) in relation to soil texture types of sediment. The major groups of macro-zoobenthos recorded were Chironomidae, Oligochaeta, Mollusca and Ceratopogonidae. The values of all water quality parameters such as temperature, water depth, rainfall, transparency, dissolved oxygen, pH, free CO2, NO3-N and PO4-P were found to have positive correlations in most cases, in some cases negative correlations and in few cases significant correlations. The abundance of Chironomidae was to be dominant in the pond no. 3 during the whole study period. The highest number of Oligochaeta (400 per m 2) was found in pond no. 3 at depth of 150 cm and the lowest number of Oligochaeta (0 per m 2) was found in pond nos. 1, 2 and 3 at both depths. The highest number of Chironomidae (1332 per m 2) was found in pond no. 3 at depth of 150 cm and the lowest number of Chironomidae (444 per m 2) was found in pond no. 2 at depth of 100 cm. The highest number of Ceratopogonidae (977 per m 2) was found in pond no. 3 at the depth of 150 cm and the lowest number of Ceratopogonidae (178 per m 2) was found in pond no. 2 at both depths. The highest number of Mollusca (1288 per m 2) was found in pond no. 3 at the depth of 150 cm and the lowest number of Mollusca (222 per m 2) was found in pond no. 2 at the depth of 100 cm. Satisfactory quantity of macrobenthos in the pond no. 3 at the depth of 150 cm than those of other two ponds. Between 2 depths (100 and 150 cm), the depth of 150 cm was to have highest quantity of macro-zoobenthos in all the three ponds because this depth was most favourable for macro-zoobenthos production. In pond no. 1, 2 and 3 relation of macro-benthos (no. per m 2) with chemical parameters of pond bottom-soil conditions vary pond to pond which influence primary production and also influence macro-zoobenthos production (secondary production). The highest macro-zoobenthos population density was found in pond no. 3 followed by pond no. 1 and the lowest production in pond no. 2 but macro-zoobenthos production in pond no. 2 and pond no. 1 are more or less similar and macro-zoobenthos production in pond no. 3 is different and higher than those of pond nos. 1 and 2 which indicates that silty clay loam of bottom-soil is more suitable for macro-zoobenthos than other soil textural classes of bottom-soil loam and sandy loam.

Meroplankton adalah organisme akuatik yang sebagian dari daur hidupnya bersifat planktonik dan merupakan fase paling kritis karena belum dapat menghindar dari predator. Untuk tumbuh, meroplankton membutuhkan kualitas perairan yang sesuai dan kawasan yang terlindung. Penelitian ini bertujuan untuk memperoleh data dan informasi kelimpahan meroplankton dan kualitas perairan di Teluk Jakarta. Pengumpulan data dilakukan pada bulan April, Juni, Agustus dan Oktober 2009 (10 stasiun) serta April dan Juni 2010 (5 stasiun) dengan metode stratified sampling. Hasil identifikasi menunjukkan bahwa meroplankton di Teluk Jakarta tahun 2009, 2010 terdiri dari 4 kelompok yaitu:ikan, telur, udang dan kepiting. Komposisi meroplankton di Teluk Jakarta pada tahun 2009 dan 2010 didominasi oleh larva udang masing-masing sebesar 56,17-90,40 % dan 72,1-75,5 %. Kelimpahan larva udang tahun 2014 lebih rendah dibanding tahun 2009-2010. Kelimpahan larva udang dipengaruhi oleh pH, salinitas, kecerahan dan suhu air.Meroplankton are aquatic organisms that part of their life cycles was planktonic that need appropriate environmental conditions and protected area for escaping from predators. The research aims to examine the composition and abundance of meroplankton in Jakarta Bay. Sampling was conducted in Jakarta Bay on April, June, August and October 2009 (10 stations) and April and June 2010 (5 stations). The samples of meroplankton collected by stratified sampling method. The results showed that meroplankton in Jakarta Bay in 2009, 2010 consists of 4 groups: fish, eggs, shrimp and crab. Composition meroplankton in Jakarta Bay in 2009 and 2010 was dominated by shrimp larvae by 56.17-90.40% and from 72.1-75.5% respectively. The abundance of shrimp larvae probably correlated with pH, salinity, terbudity and temperature of the water.
