The Ray Project - Shark, Skate and Ray Egg case Records

This dataset is comprised of the variety of skate and ray egg casings found on Wexford beaches through survey work. It includes the number of egg casings found from each species that has been identified in the process of the examination of the casings. The species found include Small-spotted catshark (Scyliorhinus canicular), Thornback ray (Raja clavata), Small-eyed ray (Raja microocellata), Blonde ray (Raja brachyura), Spotted ray (Raja montagui), Undulate ray (Raja undulata) and Cuckoo ray (Leucoraja naevus).



Geographic Coverage: The geographic extent and coverage include the described transects on the following beaches on the coast of Wexford, Cahore South Beach, Morris Castle Beach, Curracloe beach, Old Bawn Beach, Ballinoulart Bay Beach, Askingarran Lower Bay Beach, Ballinoulart Bay Beach and Fodagh Bay Beach.



Temporal Coverage: 25th of April to the 21st of July 2021



Species Groups recorded: cartilagenous fish (Chondricht



Dataset Status: Complete

Purpose

The data was originally collected to establish what species of ray and skate are still present off the coast of Ireland specifically Wexford. The data collected in this study also has the potential to lead to thorough searches being conducted all around the Irish coast along with further research on Elasmobranchs specific breeding habits, depending on the species found.

Statement

The same methodology and search effort was followed during each survey. All casings stored for 24-hour water soakage were labelled so as to avoid confusion and ensure accuracy. The process of identification was completed with the use of a widely accepted and utilised identification key sourced from Shark Trust. The same process was used for each egg casing and a photograph was taken for certainty of correct species identification. All calculations were checked by two members for accurate records of species numbers.



Data Capture Method: All survey sites were located on beaches along the coast of Wexford. The methodology conducted involved following two transect lines along the site. The first line is located 1m away from the present embryonic dunes and the second is located along the upper strand line. Egg casings are collected approximately 3 metres either side of the transect lines. This ensures egg casings present throughout the beach are collected in a similar manner each collection. The egg casings then need to be soaked in water for 24hrs before attempting to identify them. Separating the prominent species, then each egg casing is placed into a right-angle ruler on a white background. A photo is taken whilst species identification takes place by studying the size, presence of keel and presence of attachments of each casing. Once all egg casings have been identified and divided, the average size is recorded, and all information is uploaded to the egg hunt form.



Data Capture Purpose: The data was originally collected to establish what species of ray and skate are still present off the coast of Ireland specifically Wexford. The data collected in this study also has the potential to lead to thorough searches being conducted all around the Irish coast along with further research on Elasmobranchs specific breeding habits, depending on the species found.



Original Format: The data was stored in a pdf survey record sheet and excel document.
