A Litopenaeus vannamei shrimp dataset with images and corresponding weight-size measurements for the development of artificial intelligence-based biomass estimation and organism detection algorithms

Description

This dataset was compiled with the ultimate goal of developing non-invasive computer vision algorithms for assessing shrimp biometrics and biomass estimation. The main folder, labeled "DATASET," contains five sub-folders—DB1, DB2, DB3, DB4, and DB5—each filled with images of shrimps. Additionally, each sub-folder is accompanied by an Excel file that includes manually measured data for the shrimps pictured. The files are named respectively: DB1_INDUSTRIAL_FARM_1, DB2_INDUSTRIAL_FARM_2_C1, DB3_INDUSTRIAL_FARM_2_C2, DB4_ACADEMIC_POND_S1, and DB5_ACADEMIC_POND_S2. Here’s a detailed description of the contents of each sub-folder and its corresponding Excel file: 1) DB1 includes 490 PNG images of 22 shrimps taken from one pond at an industrial farm. The associated Excel file, DB1_INDUSTRIAL_FARM_1, contains columns for: SAMPLE: Reflecting the number of individual shrimps (22 entries or rows). LENGTH (cm): Measuring from the rostrum (near the eyes) to the start of the tail. WEIGHT (g): Recorded using a scale. COMPLETE SHRIMP IMAGES: Indicates if at least one full-body image is available (1) or not (0). 2) DB2 consists of 2002 PNG images of 58 shrimps. The Excel file, DB2_INDUSTRIAL_FARM_2_C1, includes: SAMPLE: Number of shrimps (58 entries or rows). CEPHALOTHORAX (cm): Total length of the cephalothorax. LENGTH (cm) and WEIGHT (g): Similar measurements as DB1. COMPLETE SHRIMP IMAGES: Presence (1) or absence (0) of full-body images. 3) DB3 contains 1719 PNG images of 50 shrimps, with its Excel file, DB3_INDUSTRIAL_FARM_2_C2, documenting: SAMPLE: Number of shrimps (50 entries or rows). Measurements and categories identical to DB2. 4) DB4 encompasses 635 PNG images of 20 shrimps, detailed in the Excel file DB4_ACADEMIC_POND_S1. This includes: SAMPLE: Number of shrimps (20 entries or rows). CEPHALOTHORAX (cm), LENGTH (cm), WEIGHT (g), and COMPLETE SHRIMP IMAGES: Documented as in other datasets. 5) DB5 includes 661 PNG images of 20 shrimps, with DB5_ACADEMIC_POND_S2 as the corresponding Excel file. The file mirrors the structure and measurements of DB4. The images for each foler are named "sm_n", where m is the number of shrimp sample and n is the number of picture of that shrimp. This carefully structured dataset provides comprehensive biometric data on shrimps, facilitating the development of algorithms aimed at non-invasive measurement techniques. This will likely be pivotal in enhancing the precision of biomass estimation in aquaculture farming, utilizing advanced statistical morphology analysis and machine learning techniques. CHANGES FROM VERSION 1: The cephalothorax metric is the length rather than the width. That was an error in the first version. The name in the columns also had a typo, which has been corrected (from CEPHALOTORAX to CEPHALOTHORAX).
