Behavioral Toxicity of Arsenic Trioxide: Alteration in Auto-Grooming Behaviour of a Freshwater Prawn, Macrobrachium Lamarrei
Open Access Austin Journal of Environmental Toxicology Research Article Behavioural Toxicity of Arsenic Trioxide: Alteration in Auto-Grooming Behaviour of a Freshwater Prawn, Macrobrachium lamarrei Munshi C1* and Bhattacharya S1 Department of Zoology, Visva Bharati University, India Abstract *Corresponding author: Munshi C, Department of Auto-grooming is the act of cleaning body parts which is a robust behaviour Zoology, Visva Bharati University, 731235, India in Macrobrachium lamarrei (Arthropoda: Crustacea: Decapoda), a highly abundant native freshwater prawn species in India. The first and fifth pairs Received: December 31, 2019; Accepted: January 22, of thoracic appendages are the major grooming appendages, which show 2020; Published: January 29, 2020 prominent signs of adaptive modifications. Grooming activity in M. lamarrei is a complex pattern, which is streamlined into two major groups, Anterior Grooming (AG) and Posterior Grooming (PG), depending on the body area. Anterior grooming is broadly divided into Carapace Grooming (CG) and Ventral Cephalothorax Grooming (VCG) and Posterior Grooming is further divided into Ventral Abdomen Grooming (VAG) and Dorsal Abdomen Grooming (DAG). Prawns were exposed to 1.72 ppm of arsenic trioxide for 15 days and the dose was found to be non lethal. Therefore, we selected this non-lethal concentration for a 24 h exposure schedule to study different grooming patterns. We report for the first time that 1.72 ppm of arsenic trioxide induced notable auto-grooming alteration in this species and the prawns were found to spend considerably more time to groom each body part compared to the control. It is concluded that grooming patterns are reliable indices of stress or sensitivity towards heavy metals in aquatic invertebrates. -

It was adopted in 2 Feb, 1971 (Thus World Wetlands Day) in the Iranian city of Ramsar (Caspian Sea) and came into force in 1975. It is the only global environmental system treaty that deals with a particular ecosystem. #joinourtelegram# Criteria for Wetlands of International Importance If it has a unique, rare example of natural wetland type. If it supports vulnerable, endangered or critically endangered species or threatened ecological communities. If it supports plant or animal species important for maintaining biodiversity of a region. If it regularly supports > 20000 waterbirds or 1% of individuals in 1 species or subspecies of waterbird. If it supports a significant proportion of indigenous fish subspecies; if it is an importance source of food for fishes, spawning ground, nursery and migration path. It is an important source of food and water resource, increased possibilities for recreation and eco-tourism, imporved scenic and educational values. Ramsar Sites in India Chillika lake was designated the first Ramsite in India in 1981. Sundarbans = largest Ramsar site. As on January 2021, there are 42 Ramsar sites in India. Sundarbans declared as the Ramsar Wetland: Sundarbans = 10000 sq km 60% in Bangladesh. It covers ~ 43% of Mangrove forests of India. It is the largest tidal halophytic mangrove forest in the world.

Note Food and Feeding Habits of Macrobrachium
Indian J. Fish., 60(4) : 131-135, 2013 Note Food and feeding habits of Macrobrachium lar (Decapoda, Palaemonidae) from Andaman and Nicobar Islands, India S. N. SETHI1, NAGESH RAM2 AND V. VENKATESAN3 1Chennai Research Centre of Central Marine Fisheries Research Institute, 75 – Santhome High Road R. A. Puram, Chennai-600 028,Tamil Nadu, India 2Central Agricultural Research Institute (CARI), Port Blair-744 103, Andaman and Nicobar Islands, India 3Central Marine Fisheries Research Institute, Cochin -682 018, Kerala, India e-mail: [email protected] ABSTRACT The stomach content of the freshwater prawn Macrobrachium lar from the inland water bodies of Andaman and Nicobar Islands were analysed in relation to size, sex and season during the period from January to December 2008. Feeding habits of M. lar were studied using the index of preponderance and feeding intensity methods. Mainly organic detritus, supplemented by animal and plant materials formed the food in all stages of M. lar. The animal food items mainly consisted of aquatic insects, polychaetes, other crustaceans, fish, molluscs and zooplankton. The plant matter was chiefly composed of fragments of aquatic plants, planktonic algae and diatoms. Variation in diet in relation to size, sex or season were found insignificant. Though, all size groups of this species feed animal and plant materials, it exhibited slight preference for animal food especially in larger size groups. Females appear to feed more actively than the males. Feeding intensity was more in monsoon season compared to dry season. Results indicate that the adults are mostly predators of slow moving benthic invertebrates rather than detritus feeders/scavengers. -

1.0 INTRODUCTION The Water (Prevention and Control of Pollution) Act, 1974 has been aimed to fulfill the water quality requirement of designated-best-uses of all the natural aquatic resources. Loss of bio-diversity on account of degradation of habitat has become the cause of major concern in recent years. Central Pollution Control Board, while executing the nation wide responsibility for water quality monitoring and management has established water quality monitoring network in the country. The Water Quality Monitoring Network constitutes 784 monitoring stations located on various water bodies all over the country. However, wetland areas have not been included as part of regular water quality monitoring network in the country. Keeping in view the importance of water quality of wetland areas, Central Pollution Control Board has initiated studies on Bio-monitoring of selected wetlands in wildlife habitats of the country. Bio monitoring of wetlands in wild life sanctuaries has been considered as most suitable measure to evaluate the health of wildlife ecosystem. Further, the monitoring of environmental variables will be immensely helpful in protecting and restoring the ecological status in these threatened habitats. 2.0 CPCB’S INITIATIVES FOR BIO-MONITORING OF WETLANDS Under the Indo-Dutch collaborative project, the development of bio- monitoring methodology for Indian river water quality evaluation was initiated during 1988. The Central Pollution Control Board carried out a pilot study on the River Yamuna for a selected stretch from Delhi upstream to Etawah downstream. The main objective of this study was to formulate strategic methods, which can be accepted in scientific and legislative framework for water quality evaluation. -

International Journal of Fisheries and Aquaculture Vol. 3(1), pp. 10-15, January 2011 Available online at http://www.academicjournals.org/IJFA ISSN 2006-9839 ©2011 Academic Journals Full Length Research Paper Food and feeding habits of the African river prawn (Macrobrachium vollenhovenii, Herklots, 1857) in Epe Lagoon, southwest Nigeria Abayomi A. Jimoh*, Edwin O. Clarke, Olusegun O. Whenu and Haleemah B. Adeoye Department of Fishery, Lagos State University, Lagos State, Nigeria. Accepted 23 November, 2010 The study investigated the stomach contents of Macrobrachium vollenhovenii from the commercial artisanal catches in Epe Lagoon in Lagos, southwest Nigeria from July to October 2008 and April to May 2009. The stomach analysis was carried out using frequency of occurrence and numeric methods. It was observed that the prawn fed on a variety of plankton species, which included chlorophyta, euglenophyta, xantophyta, chrysophyta, cladocera, copepoda, protozoa, dinoflagellate, diatoms, insect parts and unidentified food items, with chlorophyta and diatoms forming the most important food items. Chlorophyta constituted 32.00% by number and 83.62% by occurrence, diatoms constituted 31.55% by number and 65.09% by occurrence. Amongst the chlorophyta, Cosmarium granatum was the most preferred, constituting 7.93% by number and 17.67% by occurrence, followed by Ankistrodemus falcatus with 7.57% by number and 16.38% by occurrence, respectively. The least eaten food item was insect parts. The results indicated that M. vollenhovenii can be considered as an omnivorous detritivore. Key words: Feeding habits, Macrobrachium vollenhovenii, Epe Lagoon. INTRODUCTION Freshwater prawns of the genus Macrobrachium are largest species. These two species have been described decapod crustaceans belonging to the family to posses the highest commercial potential (Ajuzie and Palaemonidae. -

Saifullah Bin Aziz a, Neaz A. Hasan b, Md. Mostafizur Rahman Mondol a, Md. Mehedi Alam b, Mohammad Mahfujul Haque b,* a Department of Fisheries, University of Rajshahi, Rajshahi, Bangladesh b Department of Aquaculture, Bangladesh Agricultural University, Mymensingh, Bangladesh ARTICLE INFO ABSTRACT Keywords: This study evaluates changes in fish species diversity over time in Hakaluki Haor, an ecologically critical wetland Haor in Bangladesh, and the factors affecting this diversity. Fish species diversity data were collected from fishers using Fish species diversity participatory rural appraisal tools and the change in the fish species diversity was determined using Shannon- Fishers Wiener, Margalef's Richness and Pielou's Evenness indices. Principal component analysis (PCA) was conducted Principal component analysis with a dataset of 150 fishers survey to characterize the major factors responsible for the reduction of fish species Climate change fi Anthropogenic activity diversity. Out of 63 sh species, 83% of them were under the available category in 2008 which decreased to 51% in 2018. Fish species diversity indices for all 12 taxonomic orders in 2008 declined remarkably in 2018. The first PCA (climatic change) responsible for the reduced fish species diversity explained 24.05% of the variance and consisted of erratic rainfall (positive correlation coefficient 0.680), heavy rainfall (À0.544), temperature fluctu- ation (0.561), and beel siltation (0.503). The second PCA was anthropogenic activity, including the use of harmful fishing gear (0.702), application of urea to harvest fish (0.673), drying beels annually (0.531), and overfishing (0.513). -
E-Flow) in River Yamuna
Environmental flow (E-Flow) in river Yamuna Context: The Hon’ble NGT in its judgment dated 13 January 2015 and through subsequent directions in OA No 6 of 2012 and 300 of 2013 given directions for the maintenance of requisite environmental flow in river Yamuna downstream of the barrage at Hathnikund in Haryana and at Okhla in Delhi so that there is enough fresh water flowing in the river till Agra for restoration of the river’s ecological functions. The Hon’ble Supreme Court had in W.P. ( C ) 537 of 1992 directed on 14 May 1999, that “a minimum flow of 10 cumecs (353 cusec) must be allowed to flow throughout the river Yamuna”. The report of the three member committee of MoWR, RD and GR on Assessment of Environmental Flows (E-Flows) has in March 2015 determined scientifically that E Flows as % of 90% dependable virgin flow at downstream Pashulok Barrage, Rishikesh on river Ganga should be 65.80%. It may be noted that the situation of river Yamuna at the Hathnikund barrage in Haryana is comparable to the situation at Rishikesh on river Ganga. In addition river Ganga at Rishikesh carries far more virgin flow in it as compared to leaner river Yamuna at Hathnikund. E – Flow in river Yamuna In view of the above it has been estimated that the E Flow in river Yamuna downstream of the barrage at Hathnikund should be no less than 2500 cusec (around 70% of the average minimum virgin flow of 3500 cusec reported at Hathnikund barrage during the leanest month of January). -
INSECTICIDE TOXICITY to MACROBRACHIUM LAMARREI (H. MILNE EDWARDS) (DECAPODA, PALAEMONIDAE) by G. S. SHUKLA and OMKAR Pollution R
INSECTICIDE TOXICITY TO MACROBRACHIUM LAMARREI (H. MILNE EDWARDS) (DECAPODA, PALAEMONIDAE) BY G. S. SHUKLA and OMKAR Pollution Relevant Research Laboratory, Department of Zoology, University of Gorakhpur, Gorakhpur-273001, India INTRODUCTION Pesticides are at present used extensively for crop-protection, public health and other purposes. As a consequence of their usage, these compounds fre- quently reach the aquatic environment, either directly through spraying opera- tions or through run-off water from agricultural lands and thus contaminate the freshwater eco-system. These pesticides have been found to be extremely toxic not only to fish (Saunders, 1969; Mawdesley-Thomas, 1971; Anees, 1975) but also to crustaceans (Muncy & Oliver, 1963; Nebeker & Gaufin, 1964; Eisler, 1969; Sanders, 1969; Chaiyarach et al., 1975; Bluzat & Seuge, 1979; McLeese & Metcalfe, 1980; Shukla & Omkar, 1981). In the present investigation, three commonly used insecticides were tested for their short-term toxicity to a freshwater prawn, Macrobrachium lamarrei (H. Milne Edwards) which is a valuable source of food for fishes and human beings and is abundantly available in local water sources. METHODS Prawns were collected from Ramgarh Lake, which is situated south-east to Gorakhpur University, and acclimatized for three days to the laboratory condi- tions prior to the experiments. The insecticides used were (i) an organochlorine, endosulfan (Thiodan, 35 E. C . ), (ii) an organophosphate, methyldemeton (Metasystox, 25 E.C.), and (iii) an organocarbamate, carbaryl (Sevin, 50 W.P.), procured from local markets. Stock solutions of the insec- ticides were prepared on the day of exposure by dissolving the insecticides separately (0.1 g endosulfan (a. i. ), 1.0 g methyl-demeton (a. -
