I. A.1 DEMERSAL RESOURCES SURVEY, ASSESSMENT AND MONITORING OF FISH STOCKS ALONG NORTH MAHARASHTRA AND GUJARAT COAST BETWEEN LAT. 18°N - 23°N

Project Coordinator

Shri Ashok S. Kadam, Fisheries Scientist

Project Components

• Exploratory survey of Demersal resources using fish trawl in 100 – 500 m depth.
• Monitoring of Demersal resources using fish trawl in 30-100 m depth.
• Exploratory survey using shrimp trawl in 30-100 m depth.
• Experiments for assessment of fishing gear efficiency.
• Mesh selectivity studies with cod-end cover.

Period : April 2021 - March 2022

Project Objectives

• Preparation of species inventory of Demersal finfish and shellfish resources.
• Estimation of abundance indices of Demersal resources and major components thereof with emphasis on Sciaenids, Threadfin breams, Catfish, Bulls eye, Barracuda. Ribbon fish, Horse mackerel, Scads, Squids and Cuttlefish.
• Identifying spatio-temporal distribution pattern of above resources.
• Study of biological aspects of important resources.
• Stock assessment of important species/resources.
• Study of suitable mesh size for important species.

Survey Strategy

• Stratified random sampling
• The survey area to be divided into two sectors viz.
  • Sector I (Lat18°N - 20°N)
  • Sector II (Lat 20°N - 23°N)
• Survey cruises to be conducted alternatively in each sector. In each cruise, sampling shall begin from the farthest Latitude as far as possible.

Monofilament long line with 7/8 hooks per basket.

Survey Strategy

• The survey area to be divided into four sectors viz.
  • Sector I (Lat 4°N - 9°N), Sector II (Lat 9°N - 14°N),
  • Sector III (Lat 14°N - 18°N) and Sector IV (Lat 18°N - 23°N).
• Survey cruises will be conducted alternatively in each sector.

Operational target per cruise

IV	Lat. 18°N – 23°N	6,10,2	16

Survey area: Lat. 4°N-23°N

Collection of Environmental Data

Besides the catch and biological data being collected in longline survey, data on environmental parameters will be collected as follows:

• Salinity, Temperature and Depth (STD) data per day per set.
• Sea Surface Temperature (SST) data at specific time, one observation per set especially during immersion.
• Data on current direction and speed, one observation every day (sets are to be made at specific depth).
• Secchi disc observation (3 readings) for every set made after setting the line.
