Fade coloured fish fails to attract the interest of the buyers. In the present study an experiment were conducted to evaluate the efficacy of four types of feed (Living tubifex, Dried tubifex, Dried Daphnia and Prepared granulated feed) in the rearing of fantail guppy. Carotenoid content of the feed used, caudal fin and muscle of the fish and specific growth rate (SGR) of the fish were also analyzed. Results showed that the fantail guppy utilized the live organisms more efficiently than the artificial diet. Results are also encouraging because the fantail guppy became more brightly colourful which fed the carotenoid rich feed in comparison to the types of feed. Living tubifex was proved to be the best feed for guppy for increasing the growth and colouration.

Mangrove swamps often creates a complex ecosystems linked by biological and physical processes. A total of 92 types of juveniles of different finfish species were recorded along with their river wise distribution in three different seasons. Different diversity indices were analyzed as well as different statistical tests was performed to understand the pattern of distribution in three rivers (Hetania Doania, Muriganga and Saptamukhi) in premonsoon, monsoon and postmonsoon period.

So during the three months of culture period, from March to June 2006, the water quality was monitored in ten shrimp ponds distributed in 10 different zones. To analyze the present status, Aquatic Health Index (AHI) was evaluated by using the data of the selected ponds. The lower value of the index reflects the deteriorated condition of the culture ponds due to poor quality of source water, whereas the congenial environment for shrimp culture is indicated by higher index values. The lower value of AHI at Stn 1, Stn 8, Stn 5 and Stn 2 may be attributed to the proximity of these stations to Kulti lock gate, which receives huge quantum of untreated sewage and wastewater from the city of Kolkata. Stn 10, Stn 9 and Stn 6 offer a favorable water quality environment for shrimp culture being far away from the city and situated within mangrove-dominated Indian Sundarbans. Moreover, the use of the...

The zooplankton showed different patterns of vertical movements in different time sections of a day. The copepods and cladocerans were always found to be abundant near the surface during morning and evening whereas the rotifers showed reciprocal pattern. Copepods and cladocerans were found in lesser number collected at noon. Although the ponds were situated at the similar location, there was a difference found in the diversity and dominance of the zooplankton.
