SOME BIOLOGICAL ASPECTS OF THREE ENDANGERED FISH: Barilius bendelisis, B. barna AND B. tileo FROM THE ATRAI RIVER, DINAJPUR, BANGLADESH ARA, MOST. IFFAT- The present research was undertaken to estimate the length-weight relationship, condition factors and food habits of Barilius bendelisis, Barilius barna and Barilius tileo. Samples were collected monthly from Atrai river for six months from November 2015 to April 2016. Monthly relationships between total length (TL) and body weight (BW) as well as determination of growth pattern was performed for Barilius bendelisis, B. barna and B. tileo separately. Among 243 individuals B. bendelisis were 57, B. barna were 102 and B. tileo were 84. The total length and body weight of B. bendelisis ranged from 7 to 15.6 cm and from 3.55 to 34.1 g respectively. The total length and body weight of B. barna ranged from 4.9 to 7.9 cm and from 1.2 to 5.25 g respectively. The total length and body weight of B. telio ranged from 6.2 to 10.8 cm and from 2.61 to 11.94 g respectively. For B. bendelisis the generalized relationship of pooled data over the study period was BW = 0.020TL2.77. The study revealed high values of coefficient of determination in all months (r2 ≥ 0.869). At 95% confidence limits the „b‟ value revealed that the growth in January was isometric, and the growth in other months were allometric. B. bendelisis exhibited a higher condition factors (K) value (1.245±0.084) in February, 2016 and a lower K value (1.182±0.053) in April, 2016. For B. barna the generalized relationship of pooled data over the study period was BW = 0.017TL2.76. The study revealed high values of coefficient of determination in all months (r2 ≥ 0.820). At 95% confidence limits the „b‟ value revealed that the growth in January and April were isometric, and the growth in other months were allometric. B. barna exhibited a higher K value (1.201±0.110) in February, 2016 and a lower K value (1.110±0.226) in January, 2016. For B. tileo the generalized relationship of pooled data over the study period was BW= 0.026TL2.62. The study revealed high values of coefficient of determination in all months (r2 ≥ 0.833). At 95% confidence limits the „b‟ value revealed that the growth in January was isometric, and the growth in other months were allometric. B. tileo exhibited a higher K value (1.258±0.249) in February, 2016 and a lower K value (1.089±0.164) in April, 2016. The higher and lower mean RLG ± standard deviation (S.D.) of B. bendelisis in April and December were 2.01 ± 0.21 and 1.57 ± 0.17, respectively. The higher and lower mean RLG ± standard deviation (S.D.) of B. barna in November and January were 1.93±0.123 and 1.01±0.012, respectively. The higher and lower mean RLG±standard deviation (S.D.) of B. tileo in April and November were 1.78±0.21 and 1.25±0.180, respectively. Finally it was concluded that they are omnivore feeder. The present findings of length-weight relationship, condition factors and food habits of Barilius spp. in Atrai river might be used in future analyses of other population parameters and stock assessment of these valuable small indigenous species in Bangladesh.

FOOD HABIT AND REPRODUCTIVE BIOLOGY OF THREATENED FISH SPECIES, Cirrhinus reba (Hamilton, 1822) AKTAR, MOST. RASHADA Cirrhinus reba known as Khorkia bata or Bhagna belongs to the family cyprinidae. A study was conducted on the food habit of C. reba collected from Atrai river of Dinajpur district for a period of 6 months from September, 2015 to February, 2016. Different items of food were determined by the frequency of occurrence method. It was found that debris (22.41%) was the most dominant food item in the gut of C. reba followed by mud (18.56%) and sand (14.97%). The other food items were phytoplankton (30.85%) and zooplankton (4.31%). It was omnivorus fish with relative length of gut was (5.36 ± 1.22). Another experiment was conducted on the fecundity and GSI from March to August, 2015. Gonadosomatic index was calculated and the fecundity was determined by gravimetric method. The highest gonadosomatic index (37.38 ± 2.31) was found in the month of July. The lowest fecundity 406.67 was recorded in the fish having 16.3 cm length and 39.83 g body weight. The highest fecundity (167325) was recorded in the fish having 19.6 cm length and 93.3 g body weight. The fecundity was found to increase with the increase total length following the equation, F = 0.046 TL + 2.339 (r = 0.645) and the fecundity was also found to increase with the increase of body weight following the equation, F = 0.262 BW + 1.231 (r = 0.934). It was also found that the fecundity was increasing with equation, F = 0.700 OW - 4.817 (r = 0.853). The relationship between fecundity and total length, body weight, and ovary weight were found to be linear and significant. The investigation revealed some aspects of feeding and reproductive biology of the threatened fish C. reba. Further details investigation including histology is high required for the feeding and reproductive biology of C. reba. A THESIS BY MOST.

SEXUAL DIMORPHISM AND BODY SHAPE ANALYSIS OF GONGOTA LOACH, CANTHOPHRYS GONGOTA (HAMILTON, 1822) USING LANDMARK-BASED GEOMETRIC MORPHOMETRICS FROM THE ATRAI RIVER, DINAJPUR, BANGLADESH AKTER, MOST. MOUSUME Geometric morphometric method was used to examine sexual dimorphism and body shape variations between the sexes of Canthophrys gongota. A total of 128 (64 male and 64 female) individual of this species was collected from the Atrai river in Dinajpur district of Bangladesh. Shape data was extracted by recording 24 landmark points on two dimentionals pictures of specimens. Sexual dimorphism was found through MANOVA and ANOSIM analysis in PAST software. Discriminant function analysis (DFA) showed little overlapping of plots which were remarkably separated 99.22% the male from female. The findings in the discriminnant function analysis showed substantial variance between body shape of the sexes where female exhibited wider abdomen than male. Relative warp scores analysis indicated variation on head region, pectoral and pelvic fins between both sexes. The canonical variate analysis (CVA) scatterplots also illustrated the sexual dimorphism in the body shape of C. gongota. From this study, sexual dimorphism and variation of morphological structure of C. gongota were determined through the application of geometric morphometrics. A THESIS BY MOST.
