<div style="text-align: justify;">The proximate composition and fatty acid profile of five tissues (head, skin, bones, muscle and liver) of juvenile Siganus guttatus fed with Enteromorpha prolifera were investigated. The results indicated that: (1) The content of protein and fat among these five tissues showed a significant differences (P&lt;0.05). The muscle has the highest content of protein and the lowest content of fat. (2) The highest content of fatty acid in SFA is 16:0 in all five tissues, the highest content of fatty acid in MUFA is18:1n-9c (cis) in skin, bones, muscle and liver, while the highest content of PUFA is DHA in muscle. Muscle contained the highest value of DHA and EPA, the total content was more than 100 times in bones. Muscle tissue is rich in many important polyunsaturated fatty acids such as EPA, DPA, DHA, ARA and ALA, which has better nutritional quality and immune and health function.</div>

<div style="text-align: justify;">The present study was conducted to determine the diversity of weed species in wheat fields of the district Rajouri (J&amp;K). For analyzing diversity 20 quadrats of (1m.&times;1m.) were randomly laid down in each block. In every set of quadrat frequency, density and abundance was observed throughout the cropping season and IVI (Important value index) was determined. During the course of field study it was reported that the maximum infestation was shown by grassy weed &nbsp;Avena fatua having maximum density (10.15, 12.12, 7.30, 9.35, 10.6, 8.55 from site 1-6 respectively) and IVI (35.71, 43.49, 30.27, 33.91, 32.59, 32.11 from site 1-6 respectively) in all the selected sites. While the least dominant weeds were Calotropis procera, Conyza japonica, Cannabis sativa, Rumex acetosa, Euphorbia prolifera and Sonchus asper etc. A total of 116 weed species belonging to 3 monocot and 27dicot families were reported from the target site.</div>
