  Abstract

  Isostichopus badionotus and you will Isostichopus sp. are a couple of holothuroids cheated from the Caribbean region of Colombia. Up until now, these people were sensed just one species. During the 1 year, 222 individuals of Isostichopus sp. and 114 out-of We. badionotus was obtained in two bays of your own Santa Marta area to learn its reproductive biology and you will collect information on its proportions, lbs and you can habitat. One another sea cucumber morphotypes exhibited a yearly reproductive years, which have good reproductive 12 months away from Sep so you can November, directly related to the rise in water heat and rain. Both in sea cucumbers the populace framework shown an excellent unimodal distribution including mature people and you may an intercourse proportion of 1:1. Isostichopus sp. got the common proportions and you will pounds (193 ± 52 mm and you can 178 ± 69 g) and you may size and pounds in the beginning maturity (175 mm and you can 155 grams) which was far lower than just We. badionotus (respectively, 324 ± 70 mm and you will 628 ± 179 grams; 220 mm and 348 g). When you are 98% away from Isostichopus sp. citizens were gathered in the higher dos.5 yards, into rugged soles anywhere between fractures, 73% of We. badionotus citizens were receive ranging from step 3 and you may seven.8 m breadth, established on the sandy bottoms. This type of distinctions mean that management actions (elizabeth.grams. minimal connect dimensions) really should not be the same for sea cucumbers morphotypes.

  step one. Inclusion

  Even if sea cucumber fishing is not a traditional craft within the Colombia, for pretty much two decades it has become an additional source of income for indigenous organizations and you may fishermen to the Colombian Caribbean coast, who extract which financial support that have about no controls [1–4]. Fishing experience with surrounding countries, particularly Panama, Mexico and you can Ecuador have shown the fresh susceptability regarding ocean cucumbers so you’re able to over-exploitation on account of reasonable employment costs, later readiness and you can thickness-based breeding [5–7]. But not, within the Colombia which pastime continues to be accomplished dishonestly to your different types and you will could be mostly unregulated and you will unquantified , advised by the growing request out of Western places, in which ocean cucumber is recognized as a good gastronomic joy regarding large financial worth [8–10].

  Existing suggestions on this subject fishery and confiscations produced by Colombian ecological regulators mean that one of the variety oftentimes caught as well as finest concern for the security and you may preservation are Isostichopus badionotus [step one, step 3, 11], since it is one of the most beneficial on the Caribbean getting together with cost inside the Far-eastern places anywhere between 132 and you can 358 USD Kg -step one . Regrettably, fishermen just who offer sea cucumbers to help you intermediaries discover on average just 3 USD Kg -1 [step one, 3].
