An experiment was carried out for quality seed production of indigenous climbing perch, Anabas testudineus using cross breeding technique. Live fingerlings of A. testudineus were collected from three wild sources such as Kailla beel of Mymensingh (Mk), Salakandi beel of Mymensingh (Ms) and Shamganj beel of Netrokona (Ns) of Bangladesh. The collected wild A. testudineus were separately reared for a year in three replicated cages installed in separate earthen ponds for each stock. Forty eight mature broods (16 from each wild source stock with 1:1 sex ratio) were successfully induced bred with carp pituitary extracts following cross-breeding technique for producing three conspecific and three heterospecific cross groups. Three conspecific groups were designated as Line-1, Kailla beel ♀ × Kailla beel ♂ (Mk♀ × Mk♂); Line 2, Salakandi beel ♀ × Salakandi beel ♂ (Ms♀ × Ms♂) and Line 3, Shamgonj beel ♀ × Shamgonj beel ♂ (Ns♀ × Ns♂); whereas three heterospecific groups were designated as Line 4, Salakandi beel ♀ × Shamgonj beel ♂ (Ms♀ × Ns♂); Line 5, Kailla beel ♀ × Salakandi beel ♂ (Mk♀ × Ms♂) and Line 6, Shamgonj beel ♀ × Kailla beel ♂ (Ns♀ × Mk♂). In general, heterospecific crossbred groups (Line 4–6) showed higher reproductive performances than the conspecific crossbred groups (Line 1–3). More precisely, Line 4 (Ms♀ × Ns♂) showed the significantly (p |
