A pictorial key has been prepared for the SPECIES OF BANGLADESH. Bang. J. Life Sci.,
identification of the local nymphaild butterflies of
the forest areas of Chittagong and Cox's Bazar
collected from July 1999 to June 2002. The key is
based on the wing venation of the butterflies. The
wing venations of 719 collected nymphalid
specimens were used for the key construction in
which 17 genera with 32 species of the butterflies
were included. In the key, the specimens have been
divided into two distinct groups on the basis of
discoidal cells which are either fully closed or
partially closed in both the wings. Only three
genera have fully closed discoidal cells and the rest
have different patterns of discoidal cells.

Chittagong). FATTY ACID COMPOSITION OF
THREE MARINE FISHES OF THE BAY OF
BENGAL. Bang. J. Sci. Ind. Res., 2006, 41 (1 &
2), 47-54.
Oil samples collected from three fishes namely
Sting Ray (Dasyatis uarnak), Anchovy (Setipinna
taty), and Eel (Congresox talabonoides) from the
Bay of Bengal were analyzed to determine their
fatty acid composition with the aid of Gas Liquid
Chromatography (GLC). The saturated fatty acid
contents were 52.95, 45.28 and 52.29%; and the
unsaturated fatty acid contents were 43.97, 54.72
and 33.39% in D. uarnak, S. taty and C.
tatabonoides respectively. The highest
polyunsaturated fatty acid content was found in
S.taty (13.65%) and the lowest was in D. uarnak
(8.06 %). The ω-3 fatty acid contents were 4.58,
3.65 and 9.91 % and the ω-6 fatty acid contents
were 3.48, 10.00 and 5.50 % in D. uarnak, S. taty
and C. talabonoides respectively. Two essential
fatty acid linoleic acid (4.12 %) and arachidonic
acid (5.32 %) contents were found higher in S. taty
whereas another essential fatty acid linolenic acid
(8.98 %) found higher in C. talabonoides.
Another important polyunsaturated fatty acid
eicosapentaenoic acid (2.12%) found higher in D.
uarnak.

STUDY OF OSTEOLOGY IN SOME CHANNA

2006, 18 (1), 111-116.
From osteological study, it was found that the skull
of the four experimental species were more or less
similar in shapes, sizes and thicknesses. On the
other hand, the visceral skeleton i.e., the bones of
oromandibular region and hyoid-opercular region
were totally different from each other. But, the
branchial arches were almost identical within the
four studied species.

BIO-NUTRIENTS AND MINERALS CONTENT
OF BODY MUSCLES OF NILE TILAPIA
(OREOCHROMIS NILOTICUS) AND ITS
CHANGES WITH SEASON. Bang. J. Life Sci.,
2008, 20 (1), 23-28.
Bio-nutrients and mineral contents of body
muscles of Nile Tilapia (Oreochormis niloticus)
varied in different seasons of the year viz., winter,
summer, and monsoon. Average values of
moisture, protein, fat, and ash were 81.64±l.91%,
17.49±1.67%, 1.53±.24%, 1.48±.16% respectively.
In winter season the highest concentration of
protein (19.8l±.94%) and fat (1.8±.19%), and
lowest concentration of moisture (78.73±1.12%)
and ash (1.43±.19%) were obtained in monsoon.
The mineral contents also showed same
seasonal fluctuations. The maximum amount
of calcium (2l5.52±10mg%) and phosphorus
(177.27±23mg%) were recorded in winter, and the
minimum 121.291±.17mg% and 112.91±.49mg%
of calcium and phosphorus respectively were
found in monsoon.

identified, of which four were trematodes:
