A última carta que D. Pedro dirigiu a seu pai traz um trecho que justifica o cuidado das Cortes em não divulgar esses documentos, além do necessário para informar os deputados. Diz ele: "hei por bem declarar tods os decretos preteridos dessas facciosas,orrorosas, machiavélicas,desorganizadoras, ediondas e pestiferas Cortes, nullos, irritos e enexequiveis". Adiante, diz: "Triunfa e triunfará a Independência Brasílica ou a morte nos hade custar".

The objective of the present study was to determine the most suitable extender and their respective dilution ratios for African catfish sperm for artificial induced breeding and cryopreservation purposes. Three natural extenders were tested i.e. coconut water, sugarcane water and soybean solutions, at three different levels of sperm to extender dilutions of 1:20, 1:30 and 1:40. While Ringer solution was used as a control Diluted sperm were fertilized with ready isolated eggs to assess the fertility and hatching rate at 0, 6 and 12 hour intervals. The results showed that the eggs hatched approximately 19 to 27 hours after fertilization. In general, the fertilization and hatching rates decreased with increasing dilution ratio. With respect to natural extenders, the coconut water showed the highest fertility and hatching rates at 1:20 dilution ratio. Therefore, coconut water at 1:20 dilution ratio was the optimal condition for African catfish spermatozoa among the natural extenders investigated.

A total of 45 Male and 5 female Clarias gariepinus bred and reared in the hatchery in sunning for one year were obtained for this experiment. The fish were then housed separately according to their sexes and maintained on trout diet at 10% body weight for two days before they were subjected to induction. These were then induced using both human chorionic gonadotropin (hCG - 500iu) and carp pituitary suspension (CPS -3mg kg super(-1) suspended in 0.9% saline) either as priming or resolving doses. The milt produced was used to fertilize eggs tripped from females. The results indicated high milt production, motility and fertility in most males

Mature adult Clarias gariepinus were obtained at the ABRU hatchery in Sonning (UK), where they had beenbred and reared for several years. These were exposed to two concentrations of dieldrin in water (2.4 mu g super(-1) and 4.0 mu g super(-1). The residue analysis of diedrin in three tissues exposed for on moth at two concentrations was carried out. These were subjected to GLC analytical process. The results indicated significantly (P<0.05) higher residues in liver than in muscle and brain. The results also showed that residue levels were dependant on exposure concentration

Samples of C. gariepinus collected from the wild and cultured populations in Plateau and Niger States of Nigeria were analyzed for length-weight relationship and organ indices (Gonadosomatic index (GSI), hepatosomatic index (HSI), renalsomatic index (RSI) and somatic fat deposit index (PDI). High correlation and linear relationship between body length and body weight was observed in all sample population (P<0.05). A significant difference was observed between the GSI of males and females of both wild and cultured population and also between females of the wild and cultured population,(P < 0.05).There was no significant difference in HSI, CSI RSI and PDI of all the sample populations (P < 0.05).The importance of length-weight relationship and organ indices in fish production are discussed
