Abstract: The Fisheries Faculty of Konkan agricultural university has formulated as aquarium fish food (Flake form) "FIFOO" (Trade name) which was tested on fishes like Guppy, Molly, Swordtail, Goldfishes etc. with very promising results. The feed is regularly marketed. The feed is in two colours-natural and red coloured (with permissible additive -Tomato Red of Asian Colour Company). To find out the efficacy of this fish food is rearing of juveniles of prawns. In one month duration preliminary experiment was conducted in all glass aquarium tanks. Experimental :"FIFOO" was in the form of flakes and pellets (1.0mm size). Clams meat was used as control feed. Feed conversion ratio (FCR) and survival % of prawn juvenile of Macrobrachium rosenbergii was observed and also important observations like water quality parameters are also recorded in this paper. The result indicate that acceptance/preference of red coloured pellet feed were more in freshwater prawn which was calculated in terms of FCR and was found 2.0. The more acceptances for red coloured feed (Flake form) was also observed in case of aquarium fishes (Kovale et al 2003).

Keywords: Allelopathy, Paddy weeds, Root zone soil, Analysis of soil
Abstract: The allelopathic impact of soil collected the beneath root zone of paddy weeds viz. Cyperus difformis, Echinochloa crusgalli, Paspalum paspaloides and Sagittaria trifolia on paddy seeds like Tarom, Neda and Fajer varieties were investigated under laboratory condition in 2009. To prove the allelopathic effect of root zone soil of above weeds, the soil was analyzed to obtain the values of pH, EC, Total Nitrogen, Phosphorus, Potassium, Zinc, Copper, Manganese and Iron. The results showed that radicle length of Tarom variety were significantly affected when were allowed to growth in soil collected beneath the root zone fo Cyprus difformis over control with confidence level 95% only. Germination of above variety was significantly hampered by collected root zone soil of all selected weeds except Paspalum paspaloides. The major phytotoxicity was caused by Echinochloa crusgalli over control. The rhizosphere soil of Echinochloa crusgalli significantly diminished radicle length of Neda variety only. The soil collected beneath the roots of selected weeds suppressed hypocotyl length of above test crop while had a weak effect on percentage of germination. In case of Fajer variety, radicle length of paddy seedling was significantly hampered by all the selected weeds. Collected root zone soil of Echniochloa crusgalli proved more inhibitory effect on radicle length of test crop. Hypocotyl length of above test crop was significantly decreased due to all studied weeds while root zone soil of Echinochloa crusgalli had significant inhibitory effect on germination percentage of above test crop only. Root zone soil analysis proved that soil collected beneath the roots of Echinochloa crusgalli had less quantity of Total Nitrogen, Organic Matter, Phosphorus over other weeds and control soil. It indicates that growth of studied weed particularly Echinochloa crus galli changed soil chemistry and reduced soil nutrient content. In general, seedling growth of Fajer variety was more sensitive to allelopathic inhibition of studied weeds over Neda and Tarom varieties.

Keywords: Mudcrab, Scylla, Farming, Maharashtra
Abstract: Mudcrab considered as a very expensive seafood delicacy all over the world. The demand for live crabs in foreign market like South East Asian Countries has prompted efforts to farm large growing species of crab in confinements and harvest them at attractive sizes for exports in live form (Santhanan, 1946;Cheu, 1976). At present in India, crabs used for domestic consumptions well as for exports are largely obtained from the capture fisheries. Among the various species of crabs supporting the commercial fishery, those belonging to genus Scylla of the Family: Portunidae are commonly known as Mudcrab. They are found to grow in nature to a large size of about 22 cm in carapace width and about 2 kg in weight. On Konkan coast of Maharashtra, Mudcrab (Scylla serata) occur commonly in the shallow coastal waters, lagoons, brackish water areas, esturies, intertidal swamps and mangroves (Chappgar, 1957). The seed of this crab is available in good quantity in this region. To study the prospects of mud crab farming in Biologica Research Station, Peth Killa, Ratnagiri. During four-months experiment period, the maximum weight gain in mud crab were observed. In this experiment, the stocking density of crab was kept 4 nos/m2. It was observed that the fish head was most accepted and cheaper feed as compared to other feed forms. An economic studies revealed that the crab farming is a low cost aquaculture technology and can be transferred to the local farmers of Konkan coast of Maharashtra. The detailed experimental observatiosn of Mudcrab and their growth are presented in this paper.

Abstract: Although it is well known that forest vegetation and other environmental factors significantly contribute to the acidic forest soils, but the interplay of minerals from the parent materials or sub lying bed rock can change this scenario of soil pH. Similarly, the pH of the Takht-i-Sulaiman forest soil was observed to be near neutral to moderately alkaline varying between 7.34 and 7.70. The mineralogical assessment from the published literature indicates the occurrence of the feldspar-porphyry in the rocks of the study area. It is therefore speculated that it might be the effect of minerals like feldspars which result in elevating the pH of the soil.

Keywords: Gold fish, Lipid , growth, Maturity, Diet
Abstract: Gold fish popular among aquarium keepers due to its unique shape, coloration and hardiness. It is the most common and sought after species of aquarium fish. Therefore, its trade is ever increasing at the national as well as international level. At present, share of India in the international level is very small. One reason for this is the non-availability of the method for controlled and continues breeding of the gold fish. In the present work, an attempt was made to active growth and maturity the gold fish, C.auratus diets (feed I,II,III,IV,V,VII,VIII,IX) were prepared with differetn combinations fo lipid sources like egg yolk, vegetable oil and shark liver oil combination with wheat flour, prawn shell powder, fish meal, mineral mixture etc. The nine feeds having different lipid levels were separately tested on C. auratus fry having an average length and weight 27 mm and 310 mg respectively. The best average growth 0.448 mm (length) and 36 mg per day was obtained by feed III which was comprised with fish meal, prawn shell powder, wheat flour and mineral mixture along with 15% of lipid (egg yolk). Since feed III (15% yolk based feed) stimulated the faster growth and early maturation within 3 months, it can be used for the production of fry round the year, and can help the industry in the sphere of exports as well as in domestic market.

Abstract: The vermicomposting experiment conducted in earthen pots during June-August, 2004 with one kg each of different institutional wastes like dry grass, dry leaves, paddy straw, waste paper and wood powder mixed with two kg cow dung showed that both multiplication and growth of Eisenia foetida varied differently in different wastes. The increasing rate of earthworm population was found higher in cow dung and lower in dry leaves of Siris tree (Albizzia lebbek) at 30 days after release while at 60 days after release the increasing rate was in the order: Paddy straw>dry grass>saw dust> paper waste>cow dung>dry leaves. Less availability of food due to slow decomposition might be teh reason of lowest increasing rate of earthworm population in dry leaves. Growth of earthworm as recorded by taking weight and volume was found highest in cow dung but lowest in dry leaves. This was obvious as earthworm favoured much the cow dung as palatable food in comparison to slow decomposed dry leaves.

Abstract: Allelopathic effects of aqueous whole plant leachates of dominance weed (Cyperus difformis and Echinochloa crusgalli) and non dominance weed (Paspalum paspaloides and Sagittaria trifolia) on biochemical, physiological, growth and yield parameters of paddy rice (Tarom variety) of northern Iran were examined by foliar application of whole plant leachates of above said weeds. Spraying aqueous whole plants leachates (5%) showed that the content of phenols in flag leaf of treated crop was significantly increased by whole leachates of Cyperus difformis and Echinochloa crusgalli at P=0.05 by ANOVA. The content of total chlorophyll in flag leaf of test crop was significantly decreased by whole leachates of Cyperus difformis and Sagittaria trifolia. This study also showed that whole plant leachates of selected weeds did not show much inhibitory effect on growth parameters (number of total tillers per pot, plant height and elongation of flag leaf). On the contrary elongation of panicle and total filled grain per panicle was inhibited by foliar application of whole leachates of selected weeds. In case of number of effective tillers per pot, Cyperus difformis along Sagittaria trifolia significantly hampered on the number of effective tillers per pot only while 1000 grain weight and the number of grain per panicle were not affected by whole leachates of all treatments. However, whole plant leachates of Cyperus difformis and Sagitta trifolia strongly hampered on grain yield of Tarom variety as compared with control about 30.40 and 29.63% respectively.
