AVAILABILITY AND MARKETING OF DRY FISHES IN SOME SELECTED AREAS OF RANGPUR DIVISION Rased, Md. Mominur A study was conducted to analyze and describe the availability, price and marketing system of dry fishes in Rangpur region. This study was based on a sample survey of 80 dry fish retailers of Rangpur, Dinajpur, Panchagarh and Thakurgaon and 50 wholesalers of Chittagang, Rangpur and Saidpur. The fieldwork covered the period from January, 2013 to June, 2013. Mainly middle aged peoples were involved in this business. The main source of dry fishes for wholesale markets was Chittagang and Khulna and source for the retailers were Saidpur and Rangpur markets. Twenty two types of dry fishes were indentified in Rangpur region of which 15 were fresh water and 7 marine water fish species. It was estimated that the price of dry fishes varies from 215 Tk/ kg to 914 Tk/kg depends on species and quality of the fish. The average income of the dry fish trader ranged between 225 Tk to 437.5 Tk per day. Railway, bus, train, and rickshaw were used for transporting dry fishes. Many problems of the dry fish marketing in Rangpur region was identified such as higher transportation cost, lack of capital, lack of storage facilities, higher loan interest etc and possible measures are suggested for gradual removal of these problems with the help of related administration of the government.

Phylogenetic Relationship of Cyprinidae (Order: Cypriniformes) inferred from Morphological Traits and Mitochondrial Gene Cytochrome b. Alam, Md. Ashraful Cyprinidae is the largest fish family with more than 2000 species grouped in approximately 340 genera. The family belongs to the order Cypriniformes, of whose genera and species the cyprinids make up two-thirds. The phylogenetic relationships of the selected taxa among the cyprinidae family were inferred from the morphological traits (30 taxa) and mitochondrial gene (26 taxa) cytochrome b sequences. The average nucleotide composition were T (U) 28.2%, C 28.1%, A 29.1% and G 14.6% and Transition/Transversion bias (R) is 2.22. Faster rate of transition and transversion showed in the third codon position. Highest genetic distance was observed 0.348 in between B. bendelisis with E. danricus and in Crossocheilus and Labeo (0.350) genera. The genetic distances was 0.087 in between L. calbasu and L. gonius species and Catla and Labeo (0.10) genera. B. bendelisis showed the highest divergence time 7.62 and lowest 2.91 in C. catla and L. rohita. The result from maximum likelyhood (ML) method using morphological traits in MESQUITE and mitochondrial gene cytochrome b in MEGA 6 strongly supported monophyletic lineage of leuciscinae subfamily. L. rohita, C. reba, L. bata, L. calbasu, C. mrigala, C. catla, L. gonius, L. dyocheilus, C. carpio were closely related in both tree. C. latius and G. gotyla from garrinae subfamily were very close in both tree but not monophyletic. S. gora formed polyphyletic clade with R. bola and B. barila in both tree. D. maculatus (schizothoracinae) formed sister group with B. bendelisis in amino acid tree and with B. gonionotus in nucleotide tree. In both trees, rasborinae appeared as polyphyletic group. Combined with analysis of both morphological and molecular data this hypothesis suggested that more study are required in each subfamily that were previously proposed to resolved the phylogenetic relationships among the cyprinid.

EFFECTS OF STOCKING DENSITY ON GROWTH PARAMETERS OF GULSHA TENGRA (Mystus cavasius) IN PONDS ROY, SUSHANTA CHANDRA To know the effect of stocking density on the growth parameters of gulsha fish, an experiment was carried out in six different ponds located at Kachubari, Thakurgaon for a period of five months from 1 March to 30 July, 2015. Three stocking densities of gulsha fish such as 400 individuals decimal-1 , 500 individuals decimal-1 and 600 individuals decimal-1 were stocked as treatment 1 (T1), treatment 2 (T2) and treatment 3 (T3), respectively using Complete Randomized Design (CRD) with two replication of each treatment. Water quality parameters namely temperature, pH, dissolved oxygen and transparency were measured at fortnightly intervals. Results showed a significant difference (p<0.05) among different treatments. From this study it was found that deterioration of water quality occurs due to increasing of stocking density. Water temperature (○C) was higher and dissolved oxygen (ppm) was lower in T3. It was observed that stocking density significantly affected the growth of gulsha fish. The higher growth rate of gulsha fish was found in low stocking density. The highest length (16.5 cm) and weight (33.5 g) were obtained in T1, whereas the lowest length (14.10 cm) and weight (21.11 g) were obtained from T3. In addition, the highest specific growth rate with maximum survival rate of gulsha fish was observed in T1. From this study, it may be concluded that lower stocking density of gulsha fish produce better production and maintaining suitable water quality in pond culture condition.

CONSTRAINTS FACED BY THE WOMEN IN PRACTICING HOMESTEAD AQUACULTURE IN THAKURGAON DISTRICT Ara, Mst. Anjuman The research was undertaken to explore the involvement of rural women in different aquaculture activities and to determine the extent of constraints faced by the women in practicing homestead aquaculture. The survey was conducted in five upazila under Thakurgaon district. For questionnaire interviews, simple random sampling method was use for selection of sample from the population. A total number of 100 women, 20 form each upazila were selected and were interviewed during November 2015 to April 2016. The study was tried to explore the relationships of selected characteristics (independent variables) with constraints for practicing homestead aquaculture (dependent variable). The independent variables were age, educational qualification, family size, knowledge of aquaculture, extension contact, cosmopoliteness, pond size, and marketing orientation. Among the total 13 constraints “unavailability of training on fish culture” occupied the highest (CFI=225) score and is the first in the ranking while “lack of help from family members” had the lowest (CFI=145) score. Slightly around half (49 percent) of the respondents had medium constraints, 17 percent had low constraints and 34 percent of the respondents had high constraints for practicing homestead aquaculture. Among the eight characteristics of the farmer’s educational qualification, aquaculture knowledge, extension contact and marketing orientation showed significantly negative relationship with the constraints. On the other hand age, family size, cosmopoliteness, pond size of the respondents did not show any significant relationship with their constraints.
