Who Can Apply for BTSC Fisheries Extension Officer?
The most important eligibility condition is the educational qualification.
Candidates must possess a 4-year Bachelor’s degree in Fisheries Science (B.F.Sc.) from a College of Fisheries under an Agricultural University recognised by the Indian Council of Agricultural Research (ICAR), New Delhi.
A general graduation degree does not replace the specifically prescribed Fisheries Science qualification. Candidates should also ensure that the required qualification is held within the prescribed eligibility period.
The candidate must be an Indian citizen.
Bihar Domicile and Reservation
The reservation rules are particularly important in this recruitment. Reserved-category benefits are available only to eligible permanent residents of Bihar.
The 35% horizontal reservation for women also applies to female candidates who are permanent residents of Bihar. Candidates from outside Bihar may apply where otherwise eligible, but they should not claim Bihar’s reserved-category benefits unless they satisfy the prescribed domicile requirements.
BTSC Fisheries Extension Officer Age Limit
Age is calculated as on 1 August 2026.
| Candidate Category | Maximum Age |
|---|---|
| Unreserved Male | 37 years |
| Unreserved Female | 40 years |
| BC/EBC | 40 years |
| SC/ST | 42 years |
| Minimum Age | 21 years |
Additional upper-age relaxation is available under specific conditions, including certain provisions for persons with disabilities, eligible Bihar Government employees, contractual employees, and ex-servicemen.
Only the applicable relaxation permitted under the recruitment rules should be claimed. Candidates should keep the relevant certificate ready where an age relaxation is being claimed.
Reservation Certificates Matter
Candidates claiming reservation should pay attention to the certificate requirements rather than relying only on their category selection in the online form.
Depending on the claim, candidates may need documents such as:
- Bihar permanent residence certificate
- Caste certificate
- BC/EBC creamy-layer exclusion certificate
- EWS income and asset certificate
- PwBD certificate with the prescribed benchmark disability
- Freedom fighter dependent certificate
- Ex-servicemen documents
The relevant certificates must satisfy the authority’s prescribed conditions and dates. A candidate who selects a reservation category but cannot establish the claim during document verification may lose the corresponding benefit.
How the Selection Process Works
The recruitment uses a combination of written-test performance and eligible contractual work experience.
Computer Based Test
The CBT consists of:
- 100 objective questions
- 100 marks
- 2 hours
- Hindi and English medium
- 1 mark for each correct answer
- 0.25 mark deducted for each wrong answer
The minimum qualifying requirement is 30% in the CBT for all categories.
Where the examination is conducted in multiple shifts, BTSC may apply normalization while preparing the score.
Work-Experience Marks
Up to 25 additional marks are available for eligible contractual experience on the same post in a Bihar Government or statutory body.
The final selection calculation therefore gives:
| Component | Maximum Marks |
|---|---|
| CBT | 75 |
| Eligible contractual work experience | 25 |
| Total | 100 |
CBT marks are converted to 75 marks. For example, a candidate scoring 60% in the CBT would receive 45 marks in the CBT component.
Experience marks are considered only for candidates who qualify the CBT and must be supported by the prescribed Salary Payment Certificate.
CareerAlert24 Insight: The B.F.Sc. Requirement Is the First Check
For this recruitment, the first question should not be the number of vacancies or the exam date. It is whether the candidate has the specific 4-year B.F.Sc. qualification recognised under the notification.
The second important distinction is the merit calculation. The CBT contributes 75 marks after conversion, while eligible contractual experience can contribute up to 25 marks. Therefore, candidates claiming experience marks should not treat the experience certificate as a routine document. It must meet the prescribed requirements and be issued in the specified format by the competent fisheries authority.
The reservation rules also deserve attention because several benefits are linked specifically to Bihar domicile.
Documents to Keep Ready
Candidates should prepare clear copies of the documents applicable to their candidature, including:
- Class 10 certificate for date-of-birth proof
- B.F.Sc. degree certificate
- B.F.Sc. marksheets
- Provisional degree certificate, where applicable
- Bihar domicile certificate, where applicable
- Caste certificate
- BC/EBC creamy-layer exclusion certificate, where applicable
- EWS income and asset certificate
- PwBD certificate, where applicable
- Freedom fighter dependent certificate, where applicable
- Ex-servicemen certificate, where applicable
- Prescribed work-experience or Salary Payment Certificate, if claiming experience marks
- Valid photo identity document
- Recent photograph and signature
Candidates should upload the documents in the prescribed fields rather than assuming that missing documents can be added later during verification.

Application Mistakes Candidates Should Avoid
1. Applying without the required B.F.Sc. degree
A general Bachelor’s degree should not be treated as an alternative to the specifically prescribed Fisheries Science qualification.
2. Claiming Bihar reservation without the required domicile
Reservation benefits are subject to the prescribed Bihar domicile conditions.
3. Selecting an experience claim without the required certificate
Experience marks depend on prescribed supporting documentation. An unsupported claim may not receive marks.
4. Uploading unclear certificates
Blurred or incomplete scans can create problems during verification.
5. Entering an incorrect category
The category selected in the application can affect reservation and merit-related benefits. Candidates should verify the applicable category before final submission.
6. Waiting until the final date
The application window closes on 23 October 2026. Technical, payment or document-upload problems near the deadline can leave little time for correction.
Application Fee
The examination fee specified for this recruitment is ₹100.
The payment should be completed through the online process provided by BTSC. Candidates should retain the payment confirmation and final application copy.
