Vacancy Details: 231 Posts

Advertisement No. 28/2026 lists 231 Fisheries Extension Officer vacancies. The category-wise distribution reported for the notification is below. Candidates should cross-check the roster and any horizontal reservation details in the official PDF before selecting their category in the online form.

Category	Vacancies
Unreserved (UR)	96
Economically Weaker Section (EWS)	23
Scheduled Caste (SC)	35
Scheduled Tribe (ST)	2
Extremely Backward Class (EBC)	41
Backward Class (BC)	27
Backward Class Women (BCW)	7
Total	231

The notification also contains horizontal reservation and provisions for eligible persons with disabilities and descendants of freedom fighters. Such provisions are subject to the advertisement’s definitions, required certificates and Bihar domicile/residency conditions. Do not add horizontal-reservation figures to the main total unless the official roster explicitly treats them as additional posts.

Educational Qualification

The essential qualification is a four-year Bachelor of Fisheries Science (B.F.Sc.) degree from a College of Fisheries under an agricultural university recognised by the Indian Council of Agricultural Research (ICAR), New Delhi, as prescribed in Advertisement No. 28/2026.

Read the qualification clause in the official advertisement, not just a short summary on a job portal.
Check that the degree title, course duration and institution meet the exact notification conditions.
Keep the degree certificate, all relevant marksheets and any required recognition or institution documents ready for upload and later verification.
Do not assume that a general B.Sc. degree, an unrelated agriculture degree or work in fish farming automatically satisfies the essential qualification.

Age Limit and Relaxation

The minimum age is 21 years, with the age cut-off specified as 1 August 2026. The maximum age varies by category and gender under the recruitment rules. The published summary gives the following broad limits:

Category	Reported upper-age limit
Unreserved male	37 years
Unreserved female	40 years
BC/EBC candidates	Generally up to 40 years, subject to the notification
SC/ST candidates	Generally up to 42 years, subject to the notification

Additional relaxations may apply to specified groups such as eligible persons with disabilities, ex-servicemen, regular Bihar Government employees or eligible contractual personnel. The conditions and supporting documents differ. Use the official advertisement to calculate your age and confirm whether a relaxation applies to you; do not rely only on the table above.

Salary and Pay Level

The post is listed under Pay Level 7. The applicable basic pay, allowances, probation or service conditions and deductions must be understood from the relevant Bihar Government pay rules and the official advertisement. The actual monthly take-home amount may vary based on posting, allowances, deductions and prevailing orders. Treat salary figures on third-party websites as indicative unless the official notification states the exact amount.

Selection Process

The published selection structure combines a computer-based test with marks for eligible contractual work experience. The final merit structure is reported as 100 marks:

Component	Maximum marks
Computer-based test (CBT), converted from the written score	75
Eligible contractual work experience	Up to 25
Total	100

Experience marks are not an automatic benefit for every candidate who has worked in fisheries. The experience must meet the notification’s specific conditions and be supported by the prescribed certificate. Candidates without eligible experience should focus on meeting the educational and age conditions and preparing for the CBT.

CBT Exam Pattern

Question type: objective multiple-choice questions.
Reported paper size: 100 questions for 100 marks.
Duration: two hours.
Language: Hindi and English, as specified in the recruitment information.
Marking: one mark for a correct answer and a reported deduction of 0.25 mark for a wrong answer.
Minimum qualifying requirement: reported as 30%; confirm the precise rule in the official advertisement.
If the test is conducted in multiple shifts, the commission may apply the prescribed normalisation method.

The CBT score is reported to contribute up to 75 marks to final merit, with eligible experience contributing up to 25. For example, a score of 60 out of 100 would correspond to 45 marks in the 75-mark CBT component under a 0.75 conversion. This example illustrates the reported conversion method; the official commission’s calculation and final result will govern.

How Contractual Experience Marks Work

Experience marks are intended for candidates whose contractual service satisfies the post-specific conditions in the advertisement. The published recruitment summaries describe a maximum of 25 marks, with marks awarded proportionately according to eligible service. A candidate should not count private-sector, unrelated or undocumented work as qualifying experience unless the official rules expressly permit it.

Before claiming experience marks:

Read the exact definition of eligible contractual service in the PDF.
Check the permitted employer, post and service period conditions.
Obtain the salary/payment or experience certificate in the prescribed format from the designated authority.
Ensure that dates, designation and service details match the supporting records.
Upload the certificate only in the manner and within the deadline allowed by the application portal.

If you cannot prove that your service meets the advertisement’s conditions, do not assume it will be counted. The commission’s scrutiny and official rules determine eligibility for these additional marks.

Application Fee

Recruitment summaries report an application fee of ₹100 for all candidates, payable online, with payment-provider or bank charges potentially additional. Confirm the fee shown on the official BTSC application portal before payment. A payment receipt alone does not prove that the final application was submitted successfully.

Documents to Keep Ready

Recent photograph and signature in the portal’s required file format and size.
Valid identity and date-of-birth proof.
B.F.Sc. degree certificate and relevant marksheets.
Category certificate, if claiming a reserved category.
Bihar residence/domicile and other reservation documents, where required.
Income and asset certificate, if applicable to the EWS claim.
Disability certificate or other special-category certificate, if applicable.
Prescribed contractual-service and salary/payment certificate, if claiming experience marks.
Active mobile number, email address and online payment method.

This is a preparation checklist, not a replacement for the official document list. Upload only the documents requested by the application system and ensure each file is legible.

How to Apply Online

Open the official BTSC Advertisement No. 28/2026 page.
Download and read the complete advertisement PDF, including eligibility, age, reservation, experience and document requirements.

Register with accurate contact details and retain the registration credentials securely.
Enter personal, educational and category details exactly as supported by your certificates.
Upload the photograph, signature and documents in the specified format and size.
Review the entire form before submission. Correct any mismatch before final submission, because post-submission changes may not be allowed.

Submit the completed form and save the final confirmation page, application number and payment receipt.
Keep a copy of the final submitted application and uploaded documents for future reference and document verification.

Common Application Mistakes to Avoid

Applying with a degree that does not match the essential B.F.Sc. requirement.
Using an incorrect date of birth or calculating age against the wrong cut-off date.
Selecting a reservation category without a valid certificate or required Bihar eligibility.
Claiming contractual experience without the prescribed supporting certificate.
Uploading blurred documents, cropped signatures or files that do not meet portal specifications.
Waiting until the final hours, when network or payment problems may delay submission.
Assuming that a successful fee debit means the form has been finally submitted.
Trusting an unofficial exam date or result date before BTSC publishes it.

What Should Applicants Do Next?

As of 12 October 2026, the listed application deadline is 23 October 2026. Candidates who appear eligible should check the official notice now, prepare their certificates and submit the application well before the deadline. After applying, monitor BTSC for the syllabus, examination schedule, admit card, notices and any corrections. Do not treat a date published by a third-party website as confirmed unless it matches an official BTSC notice.

Applicants who have already submitted should retain their application and payment confirmation and periodically check the official portal. If a correction notice or clarification is issued, follow the commission’s instructions rather than editing information based on unofficial advice.
