| Stage | Process Name | Selection Process Details |
| Stage-I | Written Exam (CBT) | 100 MCQs in Hindi and English, 100 Marks, 2 Hours, +1 for Each Correct Answer, 0.25 Negative Marking, Min 30% Qualifying Marks, Normalisation for Multi-Shift Exams. Weightage: 75 Marks. |
| Stage-II | Experience Weightage | Max 25 Marks for Satisfactory Contractual Service on the Same Post (Proportionate Marks for Part of a Year). Only Candidates Qualifying the Written Exam Get These Marks. |
| Stage-III | Document Verification | Qualified Candidates Appear on the Category-Wise Merit List and Bring All Original Certificates. |
💡Important Note: You need 30% to qualify, but 231 seats mean the real cut-off will likely sit much higher, and negative marking punishes guesses. Revise core Fisheries Science topics like aquaculture and fish health until BTSC publishes the syllabus.
