Studies of filter feeding carps of commercial importance in Bangladesh with particular emphasis on the use of automated counting methods

The filter feeding capabilities of the Indian major carp Labeo rohita (Ham.) and Catla catla (Ham.) and the Chinese carp Hypophthabmichthys molitrix (Val.) were studied under laboratory conditions. An ultrastuctural and histological study of the pharyngeal apparatus associated with filter feeding of laboratory reared fish between 30 and 90 mm standard length (SL) showed that a large number of mucus cells, both small goblet and large clavate cells, were present in the bucco-pharyngeal region of all species studied and on the wall of the suprabranchial organ of H. molitrix. The density of taste buds was observed to be much greater on the roof of the pharynx and comparatively low on the roof of the mouth in all species. Among the carps studied, H. molitrix had the greatest concentration of taste buds on both the roof and floor of the bucco- pharyngeal region. An important part of the study was the development of a sound methodology for counting algal cells and colonies. An automated electronic particle counter, the Coulter Multisizer, was used to increase the speed of counting. A study was also carried out to determine the effects of the preservatives Lugol’s iodine and buffered formalin at different concentrations on both long-term and short-term storage of Pediastrum boryanum. Microcystis aeruginosa and Chlorella vulgaris. Both Lugol's iodine and buffeted formalin of different concentrations caused significant decreases in the numbers of cells and colonies during preservation. Lugol's iodine of different concentrations caused cell shrinkage in C. vulgaris and M. aeruginosa after 24 h of preservation. The abilities of carp fry and fingerlings to ingest a range of algal species were investigated. H. molitrix was found to be the most efficient among the carps studied in ingesting P. boryanum and M. aeruginosa, although C. catla was found not to be able to ingest M. aeruginosa. Ingestion rate was found to be positively correlated with algal density. It was also observed that algal size had a positive effect on ingestion rates. In a separate trial it was found that silver carp did not ingest a toxic strain of M. aeruginosa. An attempt was also made to evaluate whether these filter feeding carp could detect and ingest unattached bacteria by exposing them to the bacterium Chromobacterium violaceum in suspension. Examination of the gut contents of the exposed fish showed that the numbers of H. molitrix and L. rohita ingesting viable bacteria increased with the concentration of the bacterial suspension and with exposure time. However C. catla ingested far fewer bacteria per unit time than the other two species

Effects of stocking density on growth and production of GIFT (Oreochromis niloticus)

The study was carried out to assess the effects of stocking density on growth and production of GIFT for a period of 100 days. Three stocking densities were used 150, 200 and 250 fish/decimal; designated as treatment T1, T2 and T3 respectively having two replicates for each. Commercial pellet feeds were fed at the rate of 30% body weight up to first 10 days and then gradually it was readjusted to 22%, 18%, 15%, 12%, 10%, 8%, 6%, 5% and 4% respectively after every 10 days interval. The result showed that the fish in the treatment T1 stocked with the lowest stocking density (150 fish/dec) resulted in best individual weight gain (148.65g) followed by those in treatment T2 and T3 respectively. The specific growth rates (SGR) at every 10 days were ranged from 6.59 to 1.11 in different treatments during the experimental period. The food conversion ratio (FCR) values ranged between 1.82 to 2.03 with treatment T1 showing the lowest FCR. The survival rate ranged between 84 to 92%. Treatment T1 and treatment T2 showed significantly higher survival than Treatment T3. The fish production rate in treatment T1, T2 and T3 were 18.58, 23.87 and 26.78 kg/decimal respectively

Analisis Faktor Risiko Kejadian Pneumonia pada Balita di Wilayah Kerja Puskesmas Sidorejo Kota Pagar Alam

Background : Pneumonia is an infectious disease that remains a public health problem in Indonesia, the third cause of death in Indonesia after cardiovascular and tuberculosis. The high incidence of pneumonia mainly attacks in the age group of infants and children under five years old. In Pagar Alam city in 2009, there were 671 cases (IR = 4.9%). The purpose of this research was to determine the relationship between the house physical environment factor and individual faktor of children with pneumonia incidence in working area of Public Health Center, Sidorejo, Pagar Alam city. Method: This research was an observational study using case control design. While variables studied among other things are nutritional status, immunization status, history of breastfeeding, type of house flooring, proportion of bedroom ventilation, occupancy density, the presence of smoking family members, type of fuel used for cooking, the presence of family members suffering from respiratory tract infections. Subject of the research consists of two groups, namely case group and control group, each of which is consisting of 54 subjects. Data was collected by interview, observation, and measurement. Data analysis used analysis of univariate, bivariate with chi square, and multivariate with logistic regression, using a significant level of 0.05 (5%) to determine the risk of the independent variables on the dependent variables and the estimation of the risk (odds ratio) of the cause of pneumonia incidence on children under five years old. Result : The results of this research show that of the 9 risk factors studied, there are 3 variables with the risk of the incidence of pneumonia on children under five years old, namely a history of breastfeeding (OR = 8.958, 95% CI : 2.843 - 28.232), type of house floor (OR = 10.528, 95% CI : 2.612 - 42.441) and the presence of smoking family members (OR 8.888, 95% CI : 1.738 - 45.437). The variable at greatest risk of pneumonia incidence on children under five years old is type of house flooring. In conclusion, this research indicates that nutrition status, immunization status, breastfeeding history, type of house flooring, size of room ventilation, occupancy density, type of fuel used for cooking, and the presence of smoking family members are closely related to the incidence of pneumonia.
