In the present study, histological studies of the digestive system and SEM study of radula of Fusinus nicobaricus was evaluated. The digestive system contains proboscis, oesophagus, stomach, hepatopancreas, intestine, rectum and anus. The digestive tract of Fusinus nicobaricus encloses a buccal mass at the anterior region which contains a chitinous radula. The oesophagus leaved the buccal mass dorsally and passed the food into an extensible stomach. A pair of salivary gland lied with mid-oesophagus region. Digestive gland secreted digestive enzymes into the lumen of the stomach into mid region. Intestine was thin walled, usually long and possess loop through the digestive gland tissue and leaves as short rectum. Hepatopancreas was also implicated in storage and excretion of inorganic reserves, lipids and carbohydrate metabolites. Radula, a specific character and part of the appendices of digestive system of majority of molluscs. It was observed that the type of radula in F.n is rachiglossate with radular formula of 1+R+1.

Cellular Factors

The bactericidal and metabolic function of the phagocytic system requires integration of several complex humoral and cellular factors responding to different regulators. Polymorphonuclear leukocytes are highly mobile cells, capable of phagocytosis of bacteria or fungi with formation of a "cellular digestive system" containing reactive oxygen radicals, hydrogen ions, and digestive enzymes. The unique metabolism of oxygen in neutrophils results in release of energy as light (chemiluminescence), a response closely associated with microbial killing. Neonatal neutrophils cope with normal bacterial challenges in vitro as efficiently as adult neutrophils; however, these cells have decreased capacity for locomotion, decreased deformabiity, decreased phagocytosis in low serum concentrations, and decreased chemiluminescence. These subtle defects in function can be amplified by exaggerated challenge which may be related to a higher incidence of sepsis during the neonatal period.

The embryonic and larval development of local Guchibaim, Mastacembelus pancalus (Hamilton) was studied during May to October 2007. This study presents preliminary observations on the embryonic and larval development of Mastacembelus pancalus under laboratory conditions. The parents stock was collected from different places of Mymensingh district. The eggs were obtained through induction of spawning by use of hormones. At fertilization; the eggs were 0.50 mm in diameter. Samples were taken every 10 minutes interval till completion of morula and then every 1 hour interval up to hatching. After hatching, daily observations took place until the attainment of the fingerling stage. The eggs presented coloration varying from yellow to brownish-green. They were spherical, demersal and adhesive. The stages of embryonic development observed with cleavage, followed by blastula, morula, early gastrula, middle gastrula, late gastrula and until hatching of non-pigmented larvae which displayed total average length of 1.3 mm ± 0.22, 35 hours after fertilization. First cleavage was recorded within 1.05 hrs after fertilization and the embryonic rudiments of developing eggs appeared at 24.30 hrs at 27.0-31.0°C. The yolk sac was completely absorbed at 67 hrs during embryonic development on attainment of 5.50 mm total length. At the same time the digestive system became fully developed and the larvae searched for feeding. Keywords: Embryo; Larvae; Guchibaim; Mastacembelus pancalus DOI: 10.3329/jbau.v7i1.4984 J.
