Conceptual
Isostichopus badionotus and you may Isostichopus sp. are a couple of holothuroids rooked in the Caribbean area for Colombia. Up until now, they were felt one varieties. While in the one year, 222 folks of Isostichopus sp. and you can 114 of I. sexy runners dating badionotus had been accumulated in two bays of one’s Santa Marta part to analyze its reproductive biology and you may collect information regarding the size, pounds and you will environment. Each other water cucumber morphotypes showed a yearly reproductive period, which have a great reproductive year regarding September so you can November, directly about the increase within the water temperature and you can rain. Both in ocean cucumbers the people design displayed an excellent unimodal delivery including adult people and an intercourse proportion of just one:1. Isostichopus sp. got the typical size and you will weight (193 ± 52 mm and you may 178 ± 69 grams) and proportions and you may pounds in the beginning readiness (175 mm and you can 155 g) which was dramatically reduced than I. badionotus (correspondingly, 324 ± 70 mm and you can 628 ± 179 g; 220 mm and you will 348 grams). When you find yourself 98% off Isostichopus sp. people were obtained on upper dos.5 meters, to your rugged soles ranging from breaks, 73% off We. badionotus individuals were discovered between 3 and you can eight.8 yards breadth, started with the sandy soles. This type of distinctions mean that government tips (e.g. lowest connect dimensions) shouldn’t be a similar both for sea cucumbers morphotypes.

step 1. Addition
Whether or not sea cucumber angling is not a classic activity for the Colombia, for nearly twenty years it’s become an extra supply of money to have indigenous groups and you may anglers into Colombian Caribbean coastline, exactly who extract it financial support which have virtually no controls [1–4]. Angling expertise in surrounding places, particularly Panama, Mexico and Ecuador have indicated new susceptability out-of ocean cucumbers in order to over-exploitation due to reasonable recruitment pricing, late readiness and you can occurrence-founded breeding [5–7]. However, in Colombia so it passion remains achieved dishonestly to the additional types and you will is generally generally unregulated and unquantified , encouraged by expanding request of Far eastern locations, in which sea cucumber is considered a beneficial gastronomic glee of large monetary really worth [8–10].
Present facts on this subject fishery and confiscations made by Colombian environmental authorities indicate that one of the species normally trapped as well as ideal concern for the cover and you will maintenance try Isostichopus badionotus [1, step 3, 11], because it is probably one of the most valuable about Caribbean interacting with cost into the Western avenues between 132 and you will 358 USD Kg -step 1 . Unfortuitously, anglers which offer sea cucumbers in order to intermediaries discover an average of just step three USD Kilogram -1 [step 1, 3].
