Spatio-temporal variation of some physico-chemical parameters and abundance of planktonic community in the Atrai River, Dinajpur, Bangladesh

An experiment was conducted to assess seasonal variations of some physico-chemical parameters and plankton community of the Atrai River in Dinajpur district from August 2017 to July 2018. Summer (May to July), autumn (August to October) winter (November to January) and spring (February to April) were the four seasons of the study. Samples were collected […]

Accumulation of heavy metals and feeding habits in Cyprinidae fishes of water bodies of Khuzdar, Balochistan, Pakistan

The research area is at Khuzdar district, we evaluate heavy metals concentration in water bodies and fish organs cyprinid fish (Cyprinus carpio,Cirinus mirigla,Tor putitora, Labeorohuta and Catlacatla). We discuss the water quality, physio-chemical changes and nutritional behavior of fishes. The heavy metals i.e. Fe, Cd, Pb, and Cr were identified by Atomic Absorption Spectroscopy (AAS) […]

Effects of Light and Different Diet Types during the Nursery of Snubnose Pompano Trachinotus blochii

There is an increasing interest on snubnose pompano being a relatively new and high value aquaculture species. This study evaluated the effects of light and different diet types on the growth, survival and production of the fish during nursery culture (30 days) in brackishwater pond. The experiment utilized a complete randomized design in a factorial […]

Specific physicochemical parameters influence on the plankton structure in agbarho-ogbe-ijoh stretch of Warri River, Nigeria

The continuous discharge of effluents into Warri River, impacts on its water quality parameters as well as plankton species which requires commensurate surveillance. This study focuses on its physicochemical characteristics and their influence on plankton composition and abundance. The surface water samples and plankton collected monthly from June to November 2014 were analyzed using standard […]

Basaw Lake, with geographic location of 17˚ 36’ 12.2” to 09.9” latitude and 121˚ 49’ 21.1” to 50’ 37.9” longitude, with surface area of 15.6ha is being eyed as the next eco-tourism site of Penablanca, Cagayan, Northern Philippines. This study was undertaken to assess the biological status of Basaw Lake. Rapid biodiversity assessment using transects, […]

Limnological aspects of a riverine water body: a case study of Dhepa River in Bangladesh

The limnological study is prerequisite for the sustainability of any aquatic environment. The aim of the study was to know the physico-chemical parameters and qualitative, quantitative abundance of plankton. Dhepa River was selected for the purpose of the study. Fortnightly data were collected from three sampling sites from May to December 2014. Nine physico-chemical parameters […]

Water quality and function of Mandakini River ecosystem of Central Himalaya

Mandakini river is one of the important sources of drinking water for the rural and urban population of Rudraprayag district (Uttarakhand). It also harbours a variety of flora and fauna. A major flash flood occurred during June 16-17, 2013 which resulted into mass mortality of aquatic flora, fauna in addition to huge loss of human […]

The effect of environmental factors on rotifers abundance in Oubeira Lake (North East of Algeria)

This work aims to study the impact of the variation of physicochemical parameters on the dynamic of the zooplankton community on Lake Oubeira, a wetland of El Kala National Park. Temperature, pH and dissolved oxygen are measured in situ using a field’s multi parameters; the turbidity of the water is evaluated using a turbid meter, […]

A report on mesopelagic foraminiferal species of Hastigerinelladigitata from the neritic waters of Andaman Island

The neritic water of Port Blair Island was sampled to delineate the Planktonic foraminiferal distribution. Zooplankton samples collected each month and observed under the microscope. While a mesopelagic foraminiferal species Hastigerinelladigitata was encountered during the south west monsoon. The identified species is deep dweller and generally abundant in cooler water. So the deeper water species […]

Spatio-temporal occurrence and distribution of copepod in the Karnaphuli river estuary, Bangladesh

A total of 25 major taxa of zooplankton were identified from the Karnaphuli River of which 23 taxa during monsoon, 20 taxa during post monsoon and 20 taxa during pre-monsoon. The sampling sites count started from the Karnaphuli River mouth towards the upstream. The seasonal highest peak of zooplankton recorded 423.54 indivs/m3, 654.4 indivs/m3 and […]
