Fish Detection using Machine Learning

Looking for an expert’s professionals touch for your Machine Learning projects. gives scholars the best guidance for all research encounters that you may encounter with. Our team comprises of qualified professionals to assist you in all paper writing services. The trending topics will be suggested by us from latest IEEE papers of the current year. The fish detection using machine learning is a beneficial application in particular fields like aquaculture, marine biology, and environmental monitoring. Some of the thesis ideas are also shared stay inspired by our work.

 Let us build a fish detection system through the given guidelines,

Objective Definition

We create a machine learning model which is portable for identifying fish in images or videos and it is the initial objective of this system.

Data Collection

  • Data Source: From underwater cameras, divers, drones or other sources, we fetch the images or video footage. The data are merging of images with fish and without fish for making a binary classification setup. If species-level classification is required, then collect images for each fish pieces.

Data Preprocessing

  • Annotation: Around the fish, the images are being tagged with wrapped boxes or label them with their species names. Label box or VGG Image Annotator is involved tools we utilize in this process.
  • Image Augmentation: Augmentation methods like contrast adjustments, rotations, brightness, zooming, and flips are used by us for transforming the dataset and ignoring the over fitting.
  • Normalization: The pixel values are standardized typically the range as [0, 1].

Model Selection and Development

Let us consider the following object detection models for detecting the fish using fish detection system,

  • SSD (Single Shot Multibox Detector )
  • YOLO (You Only Look Once )
  • Faster R-CNN

The classical image classification model such as CNN (Convolutional Neural Network) is used for detecting the fish species.

Training the Model

  • Split the Data: We categorize the dataset into training, validation and test sets.
  • Training: By observing the loss and accuracy for some metrics like IoU for detection tasks, we train the model on the training dataset on the validation test.

Model Evaluation

Some generally used metrics which involves Intersection over Union (IoU), accuracy and Mean Average Precision (mAP). To perform classification task the metrics include such as, accuracy, precision, recall, and F1-score.  Our model is examined on the test dataset and observing the symptoms for class imbalance problems or over fitting.

Optimization & Hyper parameter Tuning (if required)

Based on validation set, the model architecture, learning rate, batch size or other hyper parameters are altered by us.

The tools deployed like transfer learning, here the models are pre-trained on a large dataset like ImageNet is making improvements in the fish dataset. If the fish dataset is relatively small in particular dataset, it provides us best results.


Once we get satisfied with the model, the model is used on edge devices such as cameras on underwater drones or fishing boats or the servers for batch processing of videos and images.

TensorFlow Lite or ONNX are such frameworks used on edge devices.

User Interface (if applicable)

 We are supposed in making a software tool, then design an UI (User Interface) that permit users for transferring the videos for fish detection or classification. It offers the perfect result which indicates fish with clear vision.

Conclusion & Future Enhancements

Make an outline for our project achievements and challenges faced by them. The developments which enhance our system such as,

  • Differentiating between more fish species.
  • Estimating the size or age of detected fish.
  • Real-time processing for live video streams.


In underwater process, lighting and turbidity are might different. It is critical challenge for us in making detection. So, make confirm that our dataset catches this variability.

For utilize such system, then evaluate about some ethical implications particularly for fishing activities. We must establish the system with balanced and responsible for fishing practices.

A machine learning- based fish detection system provides us more beneficial insights and techniques for the collaborators in the advancing field in marine such as, marine conservation and sustainable fishing practices. Many projects are now handled by us under machine learning our experts give scholars a brief description of the research ideas.

            We utilize the CNN method to automate fish detection and to find the kind of species from underwater image or video. We have to use several machine learning methods to test the detection of species but the size of the data has to improve and ML gives less accuracy. In ML classification methods we have the chance of arising overfitting problem when the data size is long we try to improve the method by utilizing CNN to efficacy of our proposed method.
