this paper presents  the  levels  of total  mercury  (t-hg)  in  dorsal  muscle,  liver  and  spleen of pike  (esox lucius) from  anzali  lagoon  in iran.  sampling were  carried  out from  july  2004 to july 2005. in addition 78 samples were collected. t-hg concentration  were  calculated  in relation to biometric factors. t-hg was measured by the leco ama 254 advanced mercury analyzer (usa) a...

The chromosomal spread and karyotype of Bleak (Alburnus alburnus) from Anzali lagoon were identified using tissue squashing techniques with injection of 0.5ml/100g body weight of 0.01% Colchicines solution in fish fingerlings. Kidney and gill tissues were then extracted and chopped in KCl 0.045M for 20 min and fixed in Carnoy solution in 3 stages. The chromosomal spreads were stained in 20% Gim...
