Induced breeding of crucian carp, Carassius carassius was conducted in order to determine the optimum dose of pituitary gland (PG) hormone. The research was done at the hatchery of the Freshwater Station, Bangladesh Fisheries Research Institute, Mymensingh. The study was consisted of four different doses of PG treatments (T1, T2, T3 and T4) with three replications of each. In the experiment single dose was used for T1 while double dose used for T2, T3 and T4 to evaluate the efficiency of PG hormone on ovulation, fertilization and hatching rates of C. carassius eggs. Single dose of 6.0 mg PG kg-1 body weight (bw) of female fish had no ovulatory response. The double dose in case of female fish in T2 at the rate of 6.0 mg PG kg-1 bw (1st dose 1.0 and 2nd dose 5.0 mg PG kg-1 bw at 6 h interval) and 2.0 mg PG kg-1 bw of male fish (single dose during the time of 2nd injection of female) in January showed better results in terms of ovulation (96.52±1.53%), fertilization (90.35±1.67%) and hatching rates (78.65±2.84%) compared to other treatments. Considering ovulation, fertilization and hatching rates the double dose of 6.0 mg PG kg-1 bw of female and single dose of 2.0 mg PG kg-1 bw of male can be used in induced breeding of C. carassius during January. The findings of this study indicated that induced breeding of C. Carassius is successful through PG extract and might be useful for large scale seed production in the hatchery operation.J.

Artificial Propagation

Artificial propagation of Mastacembelus pancalus was conducted in order to determine the optimum dose of pituitary  gland (PG) hormone at the hatchery of the Field Laboratory Complex, Faculty of Fisheries, Bangladesh Agricultural  University, Mymensingh. The present study consisted of two trials and each trial had four treatments (T1, T2, T3 and  T4, respectively) with three replications of each. In the experiment single dose and double dose had been used for T1,  T2, T3 and T4, respectively to evaluate the efficiency on ovulation rate, fertilization rate, and hatching rate of M.  pancalus eggs. The hatchlings were reared in aquarium up to 30 days and survival rate was determined. Treatment-3  (T3) of double dose (170mg PG kg-1 and 60mg PG kg-1 body weight of fish for female and male respectively) showed  better results in terms of ovulation rate (90.03±2.56%), fertilization rate (90±0.81%), hatching rate (80±1.84%), and  survival rate (40.00±3.19%) was recorded than other treatments of single and double dose. The water temperature  was recorded 27 to 31°C. In the present study, treatment-3 (T3 in double dose) was the best findings in terms of  ovulation rate, fertilization rate, and hatching rate which can be used in artificial propagation of M. pancalus for the  development of hatchery production. May and June are the suitable months for artificial propagation of the said  species.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.11045   J. Bangladesh Agril. Univ. 9(2): 305–310, 2011

Crucian Carp Carassius Carassius

Among vertebrates able to tolerate periods of oxygen deprivation, the painted and red-eared slider turtles ( Chrysemys picta and Trachemys scripta) and the crucian carp ( Carassius carassius) are the most extreme and can survive even months of total lack of oxygen during winter. The key to hypoxia survival resides in concerted physiological responses, including strong metabolic depression, protection against oxidative damage and–in air-breathing animals–redistribution of blood flow. Each of these responses is known to be tightly regulated by nitric oxide (NO) and during hypoxia by its metabolite nitrite. The aim of this review is to highlight recent work illustrating the widespread roles of NO and nitrite in the tolerance to extreme oxygen deprivation, in particular in the red-eared slider turtle and crucian carp, but also in diving marine mammals. The emerging picture underscores the importance of NO and nitrite signaling in the adaptive response to hypoxia in vertebrate animals.

Crucian Carp Carassius Carassius

Biochemical and histological biomarkers by the adult crucian carp (Carassius carassius (L.)) living in a biologically treated pulp mill effluent were studied. Enocell pulp mill in Uimaharju, Finland, discharges its effluents through a waste water pond to the River Pielisjoki. This pond harbours an introduced crucian carp population that apparently reproduces on site. The objective of the present study was to measure possible hormonal effects of treated pulp mill effluent on crucian carps living in a wastewater pond. Adult fish were collected for analysis by traps. A reference population was sampled from a small natural pond. Blood and bile samples were taken for analyses of hemoglobin, hematocrit, testosterone, triiodothyronine (T3), thyroxine (T4), vitellogenin, organic chlorine compounds, resin acids and neutral wood-based compounds. In addition, a histological analysis of male gonads was made. The exposed fish had higher concentration of organic chlorine compounds, resin acids and β-sitosterol in bile compared to the reference fish. The same compounds could also be found in sediment of the wastewater pond. The exposed male fish had higher liver somatic index (LSI), lower gonad somatic index (GSI), lower haemoglobin and haemocrit, but higher T3 than in the reference fish. In addition, in an average, increased plasma testosterone concentration and decreased thyroxin (T4) levels were found in the exposed male fish. No vitellogenin production was found in the exposed male fish and some females showed decreased vitellogenin levels. The histological structure of the gonads in the exposed males was normal. The results suggest more anti-estrogenic than estrogenic effects of pulp mill effluents on the crucian carp.
