AQUAAIRX MATSYA CHALLENGE 2026

Phase 1: Idea & Solution Report

Project Title: MATSYA-Node (Marine Telemetry, Species Yield & Acoustic Node)

Track: Open Marine Innovation & Sustainable Fisheries

Host Organization: AquaAirX Autonomous Systems Pvt. Ltd.

Knowledge & Scientific Partner: ICAR - Central Marine Fisheries Research Institute (CMFRI)

Academic Partner: CHRIST (Deemed to be University), Bangalore

Executive Summary

India possesses an 8,118 km coastline, an Exclusive Economic Zone (EEZ) of 2.02 million km², and over 40 lakh marine fisherfolk operating approximately 2.5 lakh fishing vessels. While traditional coastal fishermen accumulate profound ecological intuition, their knowledge remains unquantified and fragmented. Concurrently, fishers face escalating operational diesel expenditures, uncertain catch yields, and extreme oceanic safety hazards, while marine research organizations like ICAR-CMFRI lack high-resolution, near-real-time spatiotemporal observations across India's territorial waters.

MATSYA-Node resolves this dual challenge through a 4-tier, clip-on marine telemetry and zero-touch Edge AI logging architecture. Clamped to any mechanized or motorized craft in 60 seconds without permanent hull alterations, MATSYA-Node autonomously measures sea surface and depth temperature gradients, water turbidity, and bio-acoustic signatures. Using an automated triple-sensor fusion trigger, the system detects net immersion, tracks catch depth profiles, and uses an overhead camera running an INT8-quantized YOLOv8-seg model to identify dominant commercial fish species and estimate biomass using ICAR-CMFRI length-weight allometric equations.

To ensure adoption and address commercial sensitivity, MATSYA-Node operates on a Dual-Ledger Privacy Architecture: precise GPS coordinates of fishing grounds remain AES-256 encrypted on the fisherman's mobile companion, while regional, privacy-sanitized telemetry aggregated into ~8–10 km Uber H3 hexagonal bins is synchronized to the ICAR-CMFRI scientific intelligence cloud upon returning to port. At an estimated prototype Bill of Materials (BOM) cost of ₹5,450 (scaling to ₹3,600 at production volume), MATSYA-Node provides immediate 15–25% fuel savings to fishers, peer-to-peer offshore LoRa emergency communications, and a self-sustaining data pipeline for Indian marine science.

Section 1: Problem Understanding

1.1 The Macro Context: Indian Marine Fisheries

Marine fisheries form the socioeconomic backbone of India's coastal economy, contributing over ₹65,000 crore annually to the national GDP and sustaining more than 4 million livelihoods. Over 1 lakh mechanized and motorized fishing craft venture into the Arabian Sea and Bay of Bengal daily.

Despite official advisories such as INCOIS Potential Fishing Zones (PFZ) derived from satellite Ocean Colour Monitors and Sea Surface Temperature (SST) maps, small-to-medium mechanized craft (gillnetters, purse seiners, small trawlers) experience systemic operational inefficiencies:

High Fuel Expenditure: Fuel accounts for 60% to 75% of variable trip operational costs. Searching blindly for schooling fish burns ₹8,000 to ₹35,000 in diesel per voyage.
Coarse Satellite Resolution & Cloud Cover: Satellite-derived SST and chlorophyll maps suffer from optical latency and 1–4 km spatial grid coarseness, deteriorating completely during the monsoon cloud cover when coastal upwelling is most dynamic.
Data Vacuum in Fisheries Science: Research institutes such as ICAR-CMFRI rely heavily on landing center enumerations at designated harbours. While rigorous, this landing-site data cannot capture sub-surface oceanographic conditions, catch-per-unit-effort (CPUE) dynamics across depth strata, or localized environmental degradation at the exact moment of harvest.

      2.5 Lakh Boats Traversing Millions of Nautical Miles Everyday
                   Without Telemetry or Logging

1.2 Target Vessel Demographics

The proposed solution targets three dominant vessel classes operating in Indian shelf waters:

Mechanized Trawlers / Purse Seiners (35–65 ft): Multi-day vessels operating 15 to 60 nautical miles offshore, equipped with 12V/24V battery systems.
Motorized Fiberglass (FRP) Crafts (25–32 ft): Single-day gillnetters and line boats using 9.9–25 HP outboard motors (OBMs).
Traditional Country Crafts (Allu / Kandani): Non-mechanized or small motor-assisted coastal vessels operating within 12 nautical miles.

Powered by a 12V boat battery tap with an integrated 10,000mAh LiFePO4 thermal buffer battery and an optional 10W trickle solar panel.

Tier 3: Fisherman Vernacular Companion

An offline-first progressive web application (PWA) / native Android app communicating with the Deck Box over local Wi-Fi / BLE.
Pre-caches INCOIS PFZ maps, delivers real-time vernacular audio alerts (Tulu, Kannada, Malayalam, Tamil) when the vessel intersects oceanographic thermal fronts, and maintains a local cryptographic vault for catch logs.

Tier 4: Scientific Intelligence Platform

Ingests store-and-forward batch telemetry when vessels return to cellular coverage or harbour Wi-Fi gateways.
Employs spatial obfuscation algorithms mapping catches into Uber H3 Resolution 5 hexagons (~8–10 km diameter) and temporal 6-hour windows, populating a TimescaleDB/PostGIS time-series database for ICAR-CMFRI researchers.

Section 3: Value Proposition for Fishermen

Judges explicitly assess: "Why would a fisherman use it and what benefit it provides?" An extractive monitoring tool that provides no immediate financial benefit will be discarded. MATSYA-Node delivers tangible return on investment from Trip 1:

+-----------------------------------+--------------------------------------------+

3.1 Direct Fuel Optimization Through Local Thermal Front Sensing

Satellite PFZ maps indicate potential fish aggregations based on sea surface temperature gradients and chlorophyll boundaries. However, satellites pass overhead hours prior to departure, and ocean currents constantly shift these boundaries.

MATSYA-Node merges static pre-cached INCOIS PFZ maps with real-time in-situ water temperature sampled by the DS18B20 probe. When the vessel intersects a sharp thermal gradient ($\Delta T \ge 0.4^\circ ext{C}$ over 200 meters), the system issues a clear voice prompt over the deck speaker in the skipper's local dialect:

"Target thermal boundary reached. High probability pelagic schooling zone. Prepare gear."

By validating satellite forecasts with live ground-truth telemetry, search time is reduced by 1.5 to 3 hours per trip, saving 15 to 40 litres of diesel (₹1,400 to ₹3,800 saved per single-day voyage).

3.2 100% Hands-Free Autonomous Operation

Fishermen working in heavy swells with salt-covered hands and rubber gloves cannot type on mobile screens. MATSYA-Node requires zero operational intervention:

Net deployment is detected automatically via hydrostatic pressure switches.
Deck sorting is recorded automatically via edge vision.
Crew members never handle scales, cables, or interface screens while on water.

3.3 Free Offshore Emergency LoRa Mesh

Beyond 15 km from shore, cellular signals vanish. Satellite communicators (e.g., Inmarsat, Iridium) require costly hardware (₹40,000–₹80,000) and monthly subscriptions (₹3,000–₹8,000). MATSYA-Node uses Semtech SX1262 LoRa transceivers on the license-free 865–867 MHz band, forming an ad-hoc boat-to-boat mesh over 5 to 15 km sea ranges.

In events of engine failure, water ingress, or sudden squalls, a single button press on the companion app broadcasts an emergency distress packet containing vessel ID and GPS coordinates across all neighboring vessels, relaying the alert hop-by-hop back to shore.

Section 4: Data & Insights Generated (The 5 Ocean Pillars)

MATSYA-Node maps directly to the five mandatory ocean intelligence pillars outlined in the MATSYA 2026 guidelines:

Ocean Pillar	Technical Module Responsible	Measured Parameters	Scientific Output for ICAR-CMFRI
1. WHAT is present?	Sony IMX219 Camera + Edge YOLOv8n-seg + Hydrophone	Fish morphological contours, tail fork length, acoustic clicks	Species composition breakdown, juvenile bycatch percentage, biodiversity indices.
2. WHERE are they located?	u-blox NEO-M8N GPS + MS5837 Pressure Sensor	Latitude, longitude, fishing depth (m), speed, heading	3D bathymetric resource map showing species presence across depth strata.
3. HOW MUCH is available?	Optical Biomass Pipeline + Haul Duration Logger	Individual lengths ($L$), crate fill volumes ($V$), haul duration	Catch Per Unit Effort (CPUE) in kg/haul-hour, standing biomass estimates.
4. HOW do patterns change?	TimescaleDB Spatiotemporal Engine	Continuous SST, depth thermocline, turbidity, boat drift	Seasonal migration models, thermocline shift correlations, upwelling tracking.
5. WHAT does it mean?	Edge Decision Engine & Cloud Dashboard	Multivariable environmental cross-referencing	Micro-zone sustainable yield limits, juvenile protection advisories, stock health.

4.1 Detailed Mathematical Working: Dual-Mode Catch Weight Estimation

To determine catch biomass without mechanical scales, MATSYA-Node implements a two-tier optical pipeline:

                         ▼
        [ Instant Catch Weight Log (kg) ]

Method A: Allometric Length-Weight Relationship (LWR) for Individual Fish

The overhead camera maintains a fixed vantage point with a calibrated optical scale ($1 ext{ pixel} = 0.8 ext{ mm}$). YOLOv8n-seg isolates visible individual fish and calculates fork length ($L$ in cm). Fish weight ($W$ in grams) is calculated using species-specific growth constants established in ICAR-CMFRI published literature:

$$W = a \cdot L^b$$

Indian Mackerel (Rastrelliger kanagurta): $a = 0.0051,\; b = 3.12$
Oil Sardine (Sardinella longiceps): $a = 0.0063,\; b = 3.04$
Seer Fish / King Mackerel (Scomberomorus commerson): $a = 0.0078,\; b = 2.92$
White Prawn (Fenneropenaeus indicus): $a = 0.0082,\; b = 2.98$

Method B: Volumetric Packing Density for Bulk Schooling Catch

When hundreds of pelagic fish are hauled simultaneously into standard 35–40 kg plastic fish crates (~50–60 L volume), the edge camera segments crate boundaries, computes fill percentage, and estimates weight via bulk wet packing density:

$$W_{ ext{crate}} = V_{ ext{fill}} imes
ho_{ ext{species}}$$

(Where bulk wet packing density $
ho pprox 0.85 ext{ to }0.90 ext{ kg/L}$ for Indian oil sardines and mackerel).

Section 5: Real-World Feasibility & Hardware Architecture

5.1 Zero Hull Modification Mounting

MATSYA-Node requires zero structural alterations, holes, or welds:

Deck Box: Secured using an adjustable 316 stainless-steel C-clamp to the wheelhouse roof, cabin canopy pipe, or mast at a height of 1.8m to 2.5m, angled downward at 45°–60° across the deck sorting pen.
Wet Sensor Pod: Suspended over the gunwale or secured to the transom outboard motor frame using an anti-abrasion braided lanyard and stainless carabiner.
Net Depth Clip: Attached directly to the net headrope or wing rope using a snap-carabiner.

5.2 Automatic Net-Drop Triggering Mechanism

The device avoids manual buttons through Triple-Sensor Fusion:

Hydrostatic Pressure Threshold: As the net enters the water, the MS5837-30BA sensor registers hydrostatic pressure exceeding 1.05 bar ($>0.5 ext{m}$ depth). Gold-plated conductivity pins verify saltwater immersion.
Kinematic Deceleration Profile: GPS and IMU data confirm the vessel has slowed from cruising velocity (7–10 knots) to shooting/towing velocity (1.5–3.5 knots), with IMU pitch and roll registering net-tow resistance.
Automated State Transition: The system records EVENT: NET_DEPLOYED, logs timestamp and location, starts the haul timer, and records deep thermocline temperatures. Upon retrieval (pressure $<1.05 ext{ bar}$, winch vibration ceasing), EVENT: NET_RETRIEVED triggers the deck camera to log the catch sorting.

+--------------------------------------------------------------------------------+

With single-day voyages burning ₹8,000–₹15,000 in fuel and multi-day voyages burning ₹40,000+, a modest 15% fuel reduction saves ₹1,200 to ₹6,000 per voyage, achieving full capital expenditure amortization within 1 to 4 trips.

Section 6: Innovation & Scalability

6.1 Technological Novelty

Passive Decoupled Sensing: Eliminates manual data entry by extracting vessel activity, net status, and fuel proxy purely through IMU vibration, speed, and hydrostatic pressure.
Marine-Calibrated Optical Biomass Estimation: Bridges industrial computer vision with ICAR-CMFRI length-weight growth parameters on low-power edge hardware.
Zero-Airtime Mesh Networking: Replaces prohibitive satellite airtime with collaborative 865–867 MHz LoRa mesh networks for offshore safety and sensor telemetry.

 • NEVER leaves vessel     • Zero competitor can locate secret reefs!

7.1 The Dual-Ledger Cryptographic Split

MATSYA-Node enforces an architectural separation between local operational data and external scientific contributions:

Private Local Vault: Stored on the fisherman's personal device under AES-256 encryption. Contains exact GPS tracks ($\pm 2 ext{m}$), gear deployment coordinates, and trip revenues. This ledger cannot be accessed remotely or exported without explicit biometric/passcode consent.
Scientific Cloud Ledger: Before telemetry leaves the boat via cellular or harbour Wi-Fi, exact GPS coordinates are mathematically stripped. Position coordinates are converted to Uber H3 Resolution 5 hexagonal indices (representing ~8–10 km diameter cells) and timestamps are bucketed into 6-hour time bands.

This aggregation level provides marine researchers with regional abundance, biomass shifts, and environmental indicators while making it mathematically impossible for external actors to pinpoint a fisherman's private fishing spot.

Section 8: Team Composition & Execution Roadmap

8.1 Multi-Domain Skill Matrix (Maximizing Team Rubric Points)
