Dept of Limnology & Fisheries, RAU, Udaipur

ABSTRACT

The present study was carried out to elucidate the effects of Testosterone undecanoate (TU) on sex ratio and Gonadosomatic index (GS) of common carp, Cyprinus carpio var. communis.  The androgen was orally administered in three dose levels i.e. 200, 400 and 600 ppm per kg feed to 10 days old hatchings for 30 days. Fishes fed with T.U., 400 ppm resulted in 78% sterility and 19% males. The Gonadosomatic indices of sterile fishes were significantly lower (P < 0.01) than the male and female fishes of the same treatment group. This hormone was also found more economical at the recommended dose i.e. 400 ppm/kg feed, compared to some other prevalent hormones, used for the purpose of inducing sterility and maleness.

Key words: Cyprinus carpio, Testosterone undecanoate, Gonadosomatic index.

Stomach Contents of Tilapia (Oreochromis mossambicus)
from Lake Jaisamand, Udaipur (Rajasthan)
with particular reference to carp fishery

Dept of Limnology & Fisheries, RAU, Udaipur

ABSTRACT

Stomach contents of the Tilapia from commercial catches of Lake Jaisamand, Udaipur were analyzed during fishing  year 1996-97. In this Lake the species was found to feed mainly on phytoplankton (filamentous algae 5-10%, cellular algae Anacystis, 50-60%), zooplankton (10-15%) and other food items like plant tissue, insects etc. (20-30%). The amount of feed consumed varied in different samples, thus indicating the lack of preference for a particular type of diet. Further, the gastrosomatic index for different size groups ranged between 0.909 to 2.619. On the basis of this study it can be inferred that being omnivorous in feeding habit the food chain of Tilapia overlaps with those of indigenous economically valuable carps and thus likely  to affect age old traditional carp fishery. Appropriate remedial measures for sustaining carp fishery needs to be adopted.

Dept of Limnology & Fisheries, RAU, Udaipur

ABSTRACT

Satavri (Asparagus recemous Wild) herb is widely used as Ayurvedi medicine for growth and vigour as it enhance general metabolism. The conventional fish diet (@6% body weight per day (bwpd) was supplemented@ 0.1, 0.2 and 0.3 gm/kg bwpd and fed to fry of Labeo rohita (average initial weight 0.546 gm) in cement cisterns (200 l capacity). Satavari dose @ 0.2 gm/kg bwpd gave the higher (119.6%) weight increment in fry reared for 45 days. The weight increments at the doses of 0.1 and 0.3 gm/kg bwpd were 69.63% and 57.29% respectively. In control, the weight gain was 30.4%. ANOVA indicated with average weight gain and growth / day were3 significantly higher (P < 0.05) in all the treatments compared to control. Highest Sp. growth corresponds with lowest FCR and maximum GCE

ABSTRACT

A feeding trial was conducted on Indian major carp, Cirrhinus mrigala (Ham.) to evaluate the impact of the herb, Bala (Sida cordifolia) mixed with conventional diets of fish (groundnut oil cake and rice bran in 1:1) in the glass levels (excluding control) i.e. 0.06 (B1), 0.10 (B2), 0.14 (B3) and 0.18 (B4) gm/kg body wet/day and control diet was kept without herb. Experimental diets including control were fed @ 2% body weight of fish per day for 60 days. Fingerlings fed with diet B3 containing Bala @ 0.14 gm/kg body weight/day indicated relatively better growth in terms of weight gain to the extent of 26.50% whereas fingerlings fed with B1, B2, B4 and C (control) diets showed  the weight gain of 18.00, 20.94, 25.54 and 12.22% respectively. The growth per day in per cent body weight, FCR, GCE and SGR were also superior with herb supplemented diets as compared to the control.

Use of Sewage Sludge as Supplementary Diet
for the carp, Cyprinus carpio (L)

V.P. Saini and L.L. Sharma
Dept. of Limnology & Fisheries, RAU, Udaipur


ABSTRACT

Sewage sludge – a common urban refuse was tried as supplementary feed for the fish (Cyprinus carpio L average weight 4.9 g) @ 0, 50, 75 and 100%. The fish was raised on the experimental diet in plastic containers of 65.1 capacity for 60 days. Common carp fed on 100% sewage sludge failed to indicate appreciable growth. However, partial replacement (\50%) was favourable and resulted in high growth (4.58 g). Fish reared with 50% sewage sludge supplemented diet also attained high (9.12%) protein level (wet weight basis) as compared to control (9.05%) and other treatments. The bacterial load in the selected body tissues was well below the safe levels prescribed by WHO for human consumption. The values of total coliforms, faecal coliforms, E. coli and streptococci ranged between 0-7, 0-3, 0-1 and 0-3 MPN/g respectively in fish skin and muscles.

Comparative Physico-Chemical Limnology of Lakes Pichhola and Fatehsagar, Udaipur (Rajasthan)

Surendra Kumar and L.L. Sharma
Dept. of Limnology & Fisheries, RAU, Udaipur


ABSTRACT

Physico-chemical limnology of two lakes of Udaipur, Rajasthan was studied during June-August, 1987 representing late summer and monsoon periods. The comparative data on physico-chemical factors such as pH, dissolved oxygen, electrical conductance, total alkalinity and nitrates in both the water bodies were more or less the same and thus find limited use for comparing trophic status of water bodies in question. The orthophosphate concentration, however, indicated notable difference in the two lakes and justified higher productivity status of Pichhola than Fatehsagar and thus could serve as an important index of assessing trophic level besides productivity data.
Key words: Freshwater ecology, limnology, physico-chemical factors.

Dept. of Limnology & Fisheries, RAU, Udaipur


ABSTRACT

The present study describes the water quality of Bore well water of Udaipur city. The result of the bacteriological study exhibited high total coliform count (817 MPN/100 ml) in the first category and the lowest (308) in the third category. The faecal coliform, however, showed an interesting result of lowest value (19 MPN/100 ml) in highly polluted area (second category). These results clearly indicate that Bore-well water of Udaipur is not free of  contamination as seen by the presence of total and faecal coliform and horides.

Water Quality and Zooplankton Production in Waters Fertilized on the Basis of P:N Ratios

O.P. Sharma, V.K. Rajbanshi and L.L. Sharma
Dept. of Limnology & Fisheries, RAU, Udaipur


ABSTRACT

The action of two fertilizers mixed to get different ratios of P:N as Q:1, 1:2, 1:4 and 1:8 were investigated in cement cisterns. The former was single superphosphate fertilizer having P as 16% P2O5 while the latter) ammonium nitrate) contained 26% nitrogen. The results of the experiments showed that the 1:4 ratio of P:N produced greater numbers of total zooplankton  dominated by cladocerans. Interestingly, no rotifers were observed throughout the experimental period. Results also showed that addition of higher amount of nitrogen in waters is merely a wastage of the nutrient elements. Thus, it seems that the fertilizers containing P and N in the ratio of 1:4 would be an efficient chemical fertilizer for the production of cladocerans

Secretary, Udaipur Environmental Group, Udaipur


ABSTRACT

Udaipur city lies between 75'42' E longitude and 24.34N latitude in a saucer shaped valley surrounded by the hills of Aravali chain. The average rainfall is 700 mm and once upon a time had a dense forest as a natural resource. Availability of flat land is a rarity. Being sloppy land, such a physical   configuration makes only 1/5 of land available for cultivation. At times very useful agricultural land has been used for the urban growth. The area of old city is heavily crowded and people are living under sub-human conditions.

Dept. of Limnology & Fisheries, Sukhadia University, Udaipur


ABSTRACT

With a water spread of 7286 ha and a maximum depth of 32 meters, Lake Jaisamand is the largest sheet of water in southern Rajasthan. Once supporting a lucrative major carp fishery, indiscriminate fishing for a long period has changed the productivity structure of this lake. Due to lack of appropriate reservoir management strategy, the important major carp fishery has dwindled with appreciable rise in minor carps and cat fishes in the catch. The paper highlights necessary conservation measures for full utilization of productivity potential of this lake.

Growth of Common Carp (Cyprinus carpio communis L.)
                            in Waters Fertilized with NPK 

O.P. Sharma, L.L. Sharma, V.K. Rajbanshi and S.B. Karki
Dept. of Limnology & Fisheries, Sukhadia University, Udaipur

ABSTRACT

Growth studies were made for a period of 28 days for common carp fry stocked after 14 days of the day of fertilization. The waters were fertilized with varying doses of NPK mixture (18:18:10). The growth was directly proportional to the amount of fertilizer added. However, unfertilized cisterns indicated lowest fish growth. The survival was cent per cent in all the cisterns and Duncan's New Multiple Range Test revealed that the growth of fish in control differed significantly from that of the growth in treated cisterns (P < 0.01).

Some Aspects of Limnology of Amarchand Reservoir, District Rajsamand, Rajasthan: Physical Parameters

L.L. Sharma and M.C. Gupta
Dept. of Limnology & Fisheries, RAU, Udaipur

ABSTRACT

Key words: Limnology, Water quality, planktons.

A perennial reservoir in the southern Rajasthan was studied for selected limnological aspects viz temperature, turbidity and humidity to assess role of these factors on the overall productivity status.  Air temperature fluctuated between 13.4 to 41.7oC at reservoir site during study period (Dec. 90 to Nov. 91). Water temperature varied between 14.50 to 38.60 considering the entire water body. The vertical gradient in temperature was 2oC thus exhibiting a weak thermal stratification. Based on thermal characters it is presumed that mixing   occurs frequently but only partially. Complete mixing occurs only during winter, thus indicating a situation of monomictic-cum-meromictic. Water clarity values between 66.0 – 336 cm indicate comparatively clear water status and the reservoir can be placed under mild-eutrophic category following classification on the basis of water clarity. Inter-relations of temperature and turbidity have been discussed in the paper.

Significant Research and Development Achievements of
Dr. L.L. Sharma

v     For the first time bred Labeo gonius in captivity by induced breeding technique (Instl. Jorn. Acd. Ichthyol. 7(2):33-66).

v     Had been actively contributing time and energy for the growth and development of Deptt. of Limnology and Fisheries since its inception in 1979 and preparatory phase, while working as SRF in the ICAR scheme and Asstt. Professor, Zoology.

v     Designed, developed and fabricated three types of under water samplers which have been appreciated widely and published in reputed journals Current Science, Research and Industry and proceedings of 2nd Asian Fisheries Forum (Tokyo, Japan).

v     Designed and developed five types of water filters for the SWACH/UNICEF Project, one of this filter has been accepted by the UNICEF for distribution in Dracunculosis prone areas and so far over 3 lakh such filters have been distributed by the SWACH (Pollution Research) 12(3):119-125).

v     Together with other associates, developed a low cost convenient water quality (bacteriological and cyclops incidence) analysis kit which has been accepted by the UNICEF (Pollution Research) 12(3):183-185.

v     Contributed significantly on Reservoir Limnology of Rajasthan especially of Udaipur lakes. In July 1993 the District Collector, Udaipur formed a technical committee for eradication of water hyacinth from Pichhola Lake. As a member of this three member committee conducted field biological survey and submitted detailed report. Considering this report the District Administration installed two conveyer belts for removing about 10,000 metric tones of water hyacinth. The hyacinth was removed within a record period of about 2 months.
