Isostichopus badionotus and you will Isostichopus sp. are two holothuroids taken advantage of about Caribbean region of Colombia. Up until now, they were noticed just one kinds. While in the one year, 222 people of Isostichopus sp. and you can 114 from I. badionotus had been collected in two bays of the Santa Marta region to review their reproductive biology and you may assemble information on its dimensions, pounds and you may habitat. Each other sea cucumber morphotypes exhibited an annual reproductive years, that have an effective reproductive season of September to help you November, directly related to the rise within the water temperature and you will rainfall. Both in ocean cucumbers the people construction presented good unimodal delivery composed of adult anyone and you can a sex ratio of just one:step 1. Isostichopus sp. got the typical size and you may lbs (193 ± 52 mm and you will 178 ± 69 g) and you will dimensions and you may lbs in the beginning readiness (175 mm and you will 155 grams) which was far lower than simply I. badionotus (correspondingly, 324 ± 70 mm and you may 628 ± 179 g; 220 mm and 348 grams). Whenever you are 98% from Isostichopus sp. people were compiled regarding the top dos.5 yards, toward rocky soles ranging from splits, 73% away from We. badionotus people were found ranging from step 3 and you may eight.8 yards depth, open toward sandy soles. These differences mean that management tips (elizabeth.g. lowest connect size) really should not be an equivalent for both ocean cucumbers morphotypes.

Even if water cucumber angling isn’t a timeless craft from inside the Colombia, for almost two decades it is an additional way to obtain money to have local organizations and anglers into Colombian Caribbean coastline, whom pull so it investment with very nearly no controls [1–4]. Fishing knowledge of surrounding Seeking Arrangements tips countries, particularly Panama, Mexico and you may Ecuador have demostrated this new vulnerability out-of ocean cucumbers to over-exploitation due to reasonable recruitment costs, later maturity and you will density-created breeding [5–7]. However, within the Colombia so it hobby remains carried out illegally into the different variety and you will can be mainly unregulated and unquantified , recommended by the expanding request of Far-eastern areas, in which sea cucumber is recognized as an effective gastronomic pleasure out of high monetary worth [8–10].
Present details on this subject fishery plus confiscations made by Colombian ecological bodies imply that among kinds usually trapped and of greatest matter because of its cover and you can maintenance try Isostichopus badionotus [step 1, step 3, 11], since it is probably one of the most valuable throughout the Caribbean reaching prices inside Asian markets between 132 and you may 358 USD Kg -step one . Unfortunately, fishermen whom offer water cucumbers so you can intermediaries located normally simply step three USD Kilogram -step one [step 1, 3].
