	In this&amp;nbsp; study, we have studied the length-weight relationship, condition factor (Kr), gonado-somatic index (GSI) and size at first maturity of two Cichlidae species (&lt;em&gt;Tilapia zillii&amp;nbsp;&lt;/em&gt;and&lt;em&gt;&amp;nbsp;Hemichromis bimaculatus&lt;/em&gt;) from two lakes (Megarine and Temacine) of the northern Sahara (Algeria). Some 159 specimens of&amp;nbsp;&lt;em&gt;H. bimaculatus&lt;/em&gt;&amp;nbsp;and 52&amp;nbsp;&lt;em&gt;T. zillii&lt;/em&gt;&amp;nbsp;were sampled between September 2012 and July 2013. The length-weight relationship revealed an isometric value b (3.0) for&amp;nbsp;&lt;em&gt;H. bimaculatus&lt;/em&gt;&amp;nbsp;from Lake Megarine, while there was no significant difference for&amp;nbsp;&lt;em&gt;T. zillii&lt;/em&gt;&amp;nbsp;from Lake Temacine. We noted a negative allometric growth pattern (b&amp;lt;3) of males and females of&amp;nbsp;&lt;em&gt;H. bimaculatus&lt;/em&gt;. Both sexes of&amp;nbsp;&lt;em&gt;T. zillii&lt;/em&gt;&amp;nbsp;grew isometrically. The Kr did not differ significantly between months for the two studied species. It was less than 1 only in November and July for&amp;nbsp;&lt;em&gt;H. bimaculatus&lt;/em&gt;. For&amp;nbsp;&lt;em&gt;T. zillii&lt;/em&gt;, the monthly mean of Kr was always greater than 1 for all the studied period. The first sexual maturity of 50% of males was observed at 52.75mm in&amp;nbsp;&lt;em&gt;H. bimaculatus&lt;/em&gt;&amp;nbsp;and 61mm in&amp;nbsp;&lt;em&gt;T. zillii&lt;/em&gt;. The smallest mature female had a total length of 60.26mm and 66mm for&amp;nbsp;&lt;em&gt;H. bimaculatus&lt;/em&gt;&amp;nbsp;and&amp;nbsp;&lt;em&gt;T. zillii&lt;/em&gt;&amp;nbsp;respectively. The reproduction period of&amp;nbsp;&lt;em&gt;H. bimaculatus&lt;/em&gt;&amp;nbsp;and&amp;nbsp;&lt;em&gt;T. zillii&lt;/em&gt;&amp;nbsp;begins in March with an extended spawning period. The overall sex ratio was in favor of females (1: 0.7) in&amp;nbsp;&lt;em&gt;H. bimaculatus&lt;/em&gt;, and in favor of males in&amp;nbsp;&lt;em&gt;T. zillii&lt;/em&gt;&amp;nbsp;(1: 1.33). For both species, the sex ratio varied according to months and size classes.
