Title: Age and growth in the estuarine clam Katelysia opima (Gmelin) from the Vellar Estuary Authors: Kalyanasundaram, M; Than, R Kasina Abstract: Age and growth in K. opima was determined by various methods, viz. length frequency distribution, probability plot, Von Bertalanffy's equation and Ford-Walford graph. The results showed that the clam attain a length of 26.65, 36.2 and 43.15 mm during 1st, 2nd and 3rd year respectively. Page(s): 247-248

Title: Meiofauna of some sandy beaches of Andaman Islands Authors: Ansari, Z A; Ingole, B S Abstract: Comparatively high meiofauna numbers were recorded from beaches having fine sand particles than those having coarse to medium sand particles. The fauna was dominated mainly by nematodes (53.7%), harpacticoids (13.7%) and polychaetes (12.8%). On all the beaches, meiofauna concentrated in the upper 4 cm layer of the sediment. Nematodes, polychaetes and oligochaetes were present throughout the column of 10 cm core. Page(s): 245-246

Title: Uptake of plutonium by Alga Dunaliella and bivalve Meretrix Authors: Matkar, V M; Mathew, E; Chhapgar, B F; Mulay, C D; Pillai, K C Abstract: Plutonium uptake from seawater by Dunaliella indicated kd (ratio of Pu in alga to that in seawater) factors of 10⁴ similar to those obtained for sediments. However transfer ratios for Pu from contaminated sediments for Meretrix was 10^-4 for short term periods ranging up to 20 days. Page(s): 243-244
