the experiment was conducted to evaluate the prevalence of lernaea cyprinacea and its effects on growth, hematology and skin histopathology of catla catla in four experimental earthen ponds (p1, p2, p3 and p4) for 90 days. the growth performance, prevalence of lernaea cyprinacea and ulceration was recorded on a fortnightly basis. the highest final body weight was observed in p4 (413.7 g) follow...

Increased production of fish through intense culture practices often leads to not only stress and disease problems but also alteration in water quality. The organic wastes and bad water quality influence the growth of pathogenic microorganisms. Bioremediation using pond probiotics is considered a promising way to circumvent these problems. For this study, three earthen fish ponds stocked with P...

The gastrointestinal (GI) microbiome in fish plays significant roles health and disease resistance. This investigation was accomplished to enumerate, characterize identify the potential probiotic bacteria from three Indian Major Carps (IMCs), viz., rohu (Labeo rohita), catla (Catla catla) mrigal (Cirrhinus mrigala) using culture dependent methods. Altogether, 105 pathogen-inhibitory (out of 121...

The aim of the study was to investigate the physical difference in biochemical characteristics of spermatological and seminal plasma and also ultrastructure of spermatozoa in six carp species, viz. catla, Catla catla, rohu, Labeo rohita, kalbasu, Labeo calbasu, mrigal, Cirrhinus mrigala, silver carp, Hypophthalmichthys molitrix and grass carp, Ctenopharyngodon idella. Semen yield from different...

The present work was conducted to isolate and identify different parasites from Indian Major Carp (IMC) Catla catla. During the study period the severity of infection and Parasitic Frequency Index (PFI, %) were also estimated in terms of months, seasons and length groups of fishes. For the investigative purpose different districts of West Bengal were selected considering the potential of fisher...

Mosquito control with the use of insecticides is faced with the challenges of insecticide resistance in disease vectors, community refusal, their high cost, operational difficulties, and environmental concern. In view of this, integrated vector control strategies with the use of larvivorous fishes such as Guppy (Poecilia reticulata) and Gambusia (G. affinis) as biological control agents were us...

In the present study short-term (96 hr) toxicity of mercury in relation to water hardness (270 and 560 mg/l) and temperature (16 degrees C and 35 degrees C) to the fingerlings of Indian major carps, i.e. catla, rohu and mrigal has been evaluated using static bioassay. The LC5o indicates that both water hardness and temperature played significant role in mercury toxicity. The test fishes were fo...

An investigation was carried out to know the induced breeding techniques of some firewater fish species such as rui (Labeo rohita), catla (Catla catla), silver carp (Hypophthalmichthys molitrix), grass (Ctenopharyngodon idella), common (Cyprinus carpio), bighead nobilis), sharpunti (Puntius sarana) and bata bata) at Ma Fatima Fish Hatchery in Chanchra, Jashore, Bangladesh. The cost-benefit anal...
