Abstract
Isostichopus badionotus and Isostichopus sp. are a couple of holothuroids exploited on Caribbean area for Colombia. Up until now, they were experienced one kinds. During the 1 year, 222 folks of Isostichopus sp. and you may 114 of We. badionotus have been compiled in 2 bays of your own Santa Marta area to examine its reproductive biology and you may collect information on their size, lbs and environment. Each other sea cucumber morphotypes displayed a yearly reproductive years, that have good reproductive season out-of September in order to November, directly connected with the increase in the water temperature and you can water. In water cucumbers the populace build demonstrated an excellent unimodal distribution composed of mature individuals and you may a gender proportion of 1:step one. Isostichopus sp. got the average dimensions and you may lbs (193 ± 52 mm and you may 178 ± 69 grams) and proportions and you may pounds to start with readiness (175 mm and you will 155 g) which had been dramatically reduced than simply I. badionotus (correspondingly, 324 ± 70 mm and you can 628 ± 179 g; 220 mm and you can 348 grams). When you find yourself 98% away from Isostichopus sp. people were built-up about upper dos.5 m, to your rocky bottoms between breaks, 73% of I. badionotus people were found ranging from step three and you will seven.8 m depth, unsealed towards the exotic bottoms. This type of variations signify management methods (age.grams. lowest catch dimensions) should not be an equivalent https://datingmentor.org/escort/rockford/ both for ocean cucumbers morphotypes.

1. Introduction
Even when water cucumber angling is not a vintage passion inside the Colombia, for nearly two decades it’s become an extra way to obtain money to possess indigenous organizations and you may anglers to your Colombian Caribbean shore, which pull it investment that have very nearly zero controls [1–4]. Fishing experience in surrounding nations, including Panama, Mexico and you can Ecuador have shown the brand new vulnerability away from ocean cucumbers so you’re able to over-exploitation on account of lowest recruitment rates, later readiness and you can thickness-oriented reproduction [5–7]. However, in Colombia this passion has been carried out dishonestly into the different types and may be mostly unregulated and you will unquantified , encouraged of the growing consult away from Far-eastern areas, where sea cucumber is known as an effective gastronomic joy away from large monetary really worth [8–10].
Current info on this fishery along with confiscations produced by Colombian environmental government signify one of the varieties frequently trapped as well as top question for the cover and you may maintenance are Isostichopus badionotus [step 1, step three, 11], because it is probably one of the most rewarding regarding the Caribbean interacting with cost in the Western places anywhere between 132 and you may 358 USD Kilogram -1 . Sadly, fishermen whom sell sea cucumbers in order to intermediaries found typically only step three USD Kilogram -1 [1, 3].
