Asymptotic length (L∞) ranged from 36.23 cm ( Brycinus macrolepidotus ) to 18.8 cm ( Hemichromis fasciatus ). Growth rates (K) varied between 1.6 yr -1 and 0.66 yr -1 with growth performance index (Φ’) ranging from 2.4 to 3.1. Theoretical age at length zero (t 0 ) varied -0.95 year for Marcusenius senegalensis to -0.59 year for Shilbe intermedius . Except for B. macolepidotus , total mortalities were higher than 2 year -1 and length at first capture (L 50 ) ranged 7.72-12.09 cm. Marcusenius senegalensis and S. intermedius showed one annual peak of recruitment, whereas H. fasciatus , Oreochromis niloticus and B. macrolepidotus displayed two peaks. The results indicated that the stocks of these five species were underexploited. However, the low length at first capture (L 50 ) recorded for some species, requires the implementation of early fisheries management scheme to assure a sustainable exploitation of these fishes.","PeriodicalId":36975,"journal":{"name":"International Journal of Aquatic Biology","volume":"22 1","pages":"332-341"},"PeriodicalIF":0.0,"publicationDate":"2019-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86856470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fish with an average weight of 5.52±0.45 g were exposed to different concentrations of un-ionized ammonia (UIA) to determine median lethal concentration (96-h-LC 50 ). The fish were exposed to six different concentrations of UIA (control, 0.16, 0.31, 0.62, 0.94 and 1.25 mg/l UIA). The control group was not challenged with ammonia (0.0008 mg/l UIA). The results showed that the 96-h-LC 50 of UIA in Persian sturgeon was 0.46 mg/l. According to 96-h-LC 50 ,mid-term exposure to sub-lethal UIA was examined. In the chronic examination, the fish were exposed to different levels of sub-lethal ammonia; control (0.0008 mg/l UIA), 10% of LC 50 (0.05 mg/l UIA), 5% of LC 50 (0.025 mg/l UIA) and 1% of LC 50 (0.005 mg/l UIA) for 30 days. Final length, final weight, weight gain, specific growth rate, daily weight gain and body weigh index decreased significantly in the fish exposed to 0.05 and 0.025 mg/l UIA.

The plant material was collected in a tributary of the Rio Igaracu, Parnaiba, Piaui State, Brazil. A botanical description of the species was made using individuals collected in the study area. For the germination tests, a total of 1400 seeds were harvested and three experiments were conducted, varying the amount of available water, light and temperature. The results showed that the highest percentage of germination is occurred with seeds pre-washed with distilled water, sown on filter paper with abundant water (enough to form a sheet of water) and exposed to alternating light at an average temperature of 37°C. Germination began on the fourth day after sowing, marked by the appearance of the cataphyll. After 22 days, the seedling stage was completed. Vegetative propagation of this species is efficient and fast. In 50 days, a total of 134 new vegetative shoots were recorded in just one individual. The results showed that the germination rate is related to the amount of light and temperature.","PeriodicalId":36975,"journal":{"name":"International Journal of Aquatic Biology","volume":"26 1","pages":"322-331"},"PeriodicalIF":0.0,"publicationDate":"2019-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89727532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
