Some feeding experiments were therefore conducted to test the effect of two different types of rations on the milch cattle (buffaloes), one consisting of groundnut cake in combination with
Results obtained show the following:-
Inclusion of cotton seed in the ration fed to which buffaloe does not show any particular advantage over a ration consisting of groundnut cake and
Average daily milk yields of the various animals were neither adversely affected nor particularly improved by the exclusion or inclusion of cotton seed in their daily diet and no characteristic variations in the percentage of fat in the milk were observed. These results are significant as they definitely show that the quality (commonly understood as the percentage of fat) of the milk is not in any way lowered by the exclusion of cotton seed from the diet,
Cotton seed, however, significantly affects the characteristics of the butter fat by increasing its melting point, and by lowering the proportion of the volatile water-soluble and insoluble fatty acids contained in it.
These results further establish the important fact that market samples of genuine butter and

In the rainy season (from June 15th to the end of September) the Weather Was less settled and there were thunder storms and heavy showers of rain. There was a considerable disturbance in the sea and the water was mixed over great depths during this period. In the remaining part of the year the winds were lighter and the mixing of water less pronounced. The sky was overcast with clouds for the most part of the. rainy season and there was a bright sun light from October to the end of May 1945.
The temperature of Water varied between 24° C. and 32.5° C. The maximum temperature of air was recorded as 103.1° F. on 24th March, 1945.
The salinity was low in the rainy season.—23.56‰ on 17th July, 1944 and high in the summer—38.4‰ on 21st May, 1945.
The range of Hydrogen-ion concentration was 7.8 to 8.35.
Phosphates were found in quantities varying between 13.04mg./m3 and 37.8mg./m3. It was as high as 51.9mg./m3 in one sample.
The amount of dissolved silica was greater than any other chemical constituents recorded here. The lowest value was 315mg./m3 and the highest 1953mg./m3.
The minimum and maximum quantities for nitrite were 4.60mg./m3 and 167.1 mg./m3 and for ammonia 9.84mg./m3 and 156.3 mg./m3 respectively.

In the present investigation extending over a period of two years from June 1945 to June 1947, the stomach contents of 2,188 young fishes belonging to 21 species were examined for determining their food and feeding habits.
The young forms of almost all the species are surface plankton feeders, and are carnivorous, except
Planktonic prawn larvae mostly belonging to the genus
Diatoms in fairly high percentages were taken by
Amongst the Percidæ, the amphipods formed an important item of food in addition to prawn larvæ and copepods.
The younger forms of all the Sciænids take prawns as their main food, and the percentage of their fish food goes on slowly increasing as they grow in size.

2. The female fish have been classified as Immature, Maturing, Mature and Spent, with reference to the condition of their ovaries. The mature ovum contains a single oil globule generally measuring between 0·13 mm. and 0·15 mm. in diameter.
3. A study of the maturation cycle brought out three phases in the life of the fish:

6. The smallest male specimen with ‘mature’ testes measured 224 mm. The males attain a relatively smaller size, the maximum size noted being 273 mm.
7. The number of mature eggs liberated in a single spawning has been found to vary from 16,682 to 166,130 in sizes of fish ranging between 184 mm. and 340 mm. in total length.

1. Seasonal gonadal changes in adult mussels were observed.
2. The spawning starts in the month of March and continues up to October indicating a prolonged breeding period.
3. After the start of the spawning, lipid globules appear in the lumen of the follicles.
4. In the male, spermatocytical morulae appear after the start of the spawning.
5. No indeterminate sex condition or hermaphroditism is noticed.
