“…According to Berté et al (2008), the length of first maturity of D. rostratus in Bandama River was 39.6 cm SL for males and 46.3 cm SL for females. In this work, higher age at maturity (tm) values were reported for female 3.78 years.…”

“…According to Berté et al (2008), the size of first maturity of D. rostratus from Bandama River is 46.3 cm SL for females and 39.6 cm SL for males. This result shows that fishes were caught at smaller sizes before they had the chance to grow large enough and to breed to contribute substantially to stock biomass.…”

Growth and mortality parameters, exploitation rates and annual recruitment patterns were estimated using FiSAT program from monthly length-frequency and weight samples of Distichodus rostratus captured from the hydrosystem located between the hydroelectric dams of Kossou and Taabo (Bandama River). Samples were collected from July 2004 to June 2005. The aim was to estimate growth parameters, mortality rates, exploitation rate and recruitment pattern of D. rostratus for sustainable management. The von Bertalanffy growth parameters asymptotic length L∞ (cm) and growth constant K (per year) were 69.30 and 0.27 respectively. Goodness of fit (Rn) was 0.27. The growth performance index (φ') value was 3.11. Age at maturity was estimated at 2.87 years for males and 3.78 years for females. The maximum age estimated was 11.095 years. The annual rate of fishing mortality (F = 0.10) was low compared to the relatively high natural mortality (M = 0.60). The exploitation rate (E = 0.14) shows that the species was not over-exploited in the Bandama River.

“…L'une pré forestière au nord et l'autre forestière à savanes incluses au sud (Groga, 2012). On distingue deux saisons des pluies (une grande allant d'avril à juin, une petite de septembre à novembre) et deux saisons sèche (la plus longue de décembre à mars et la petite de juillet à septembre (Berté et al, 2008). En outre, une grande partie du lac est occupée par des végétaux aquatiques (Aliko et al, 2010).…”

A study of Synodontis punctifer (family: Mochokidae) of Taabo Lake was conducted from October 2015 to September 2016. This was carried out so as to evaluate its quantity (biomass) caught by fishing and also its morphological characteristics. The fish were caught using gillnets at 4 sites of the lake and different measurements were made. The fishing effort was 23 to 11 fishermen / day in Taabo city, 17 to 11 fishermen / day in Courandjourou, 13 to 5 fishermen / day in Ahondo, and 8 to 3 fishermen / day in Taabo village. The catch per unit effort (CPUE) ranged from 17.7 to 3.7 g / fisherman / day, 9.2 to 1.2 g / fisherman / day, 8.3 to 0.7 g / fisherman /day, 8 to 1g / fisherman / day at Ahondo, Courandjourou, Taabo city and Taabo village, respectively. The overall annual production was estimated at 2199.3 kg, i.e. 817 kg (40%) at Ahondo, 788.3 kg (35%) at Courandjourou, 462.5 kg (20%) at Taabo, and 131.5 kg (5%) in Taabo village. The overall sex ratio (1: 1.33) was in favor of females. Individuals have negative allometric growth at all sites with values ranging from 1.72 to 2.89. The condition factor does not vary significantly between different categories of individuals (ANOVA, F = 2.79, p ˃ 0.05). A significant difference was observed between the average sizes of the individuals of the different sites (test, p˂0,05). The large size specimens were captured at Ahondo, mean (avg = 15.38 ± 1.68 cm FL). In Courandjourou, the sizes were intermediate (avg = 13.63 ± 1.64 cm LF). Smalls sizes have been observed in Taabo city (mean= 12.37 ± 1.24 cm FL) and Taabo village (mean= 15.58 ± 1.58 cm FL).

“…Many organs were rapidly removed, washed with 0.1 M phosphate buffered saline (pH 7.4), weighed and stored at -20°C for the determination of organo-somatic indexes and glutathione metabolising parameters. The organo-somatic indexes show the weight of each organ as a percentage of body weight [17]. The reduced glutathione was determined spectrophotometrically, according to the Weckbecker and Cory method [18], the glutathione S-transferase activity was estimated by Asaoka and Takahashi method [19] and the content of total protein by the method of Bradford [20].…”
