  Isostichopus badionotus and you can Isostichopus sp. are two holothuroids cheated from the Caribbean area for Colombia. Up until now, these people were considered just one kinds. During the one year, 222 individuals of Isostichopus sp. and you will 114 of We. badionotus was in fact accumulated in 2 bays of Santa Marta area to study the reproductive biology and assemble information about their proportions, weight and you will habitat. Both ocean cucumber morphotypes presented a yearly reproductive duration, that have a beneficial reproductive 12 months away from Sep in order to November, closely related to the rise in water temperatures and rainfall. Both in ocean cucumbers the populace structure displayed a good unimodal shipments composed of adult some body and you may an intercourse proportion of just one:step one. Isostichopus sp. had the typical dimensions and you can weight (193 ± 52 mm and 178 ± 69 grams) and proportions and you will pounds to start with readiness (175 mm and 155 g) that has been dramatically reduced than simply We. badionotus (correspondingly, 324 ± 70 mm and you will 628 ± 179 grams; 220 mm and you may 348 g). If you find yourself 98% regarding Isostichopus sp. citizens were obtained about higher dos.5 meters, on the rugged bottoms between cracks, 73% away from I. badionotus everyone was discovered between 3 and you may eight.8 meters breadth, established towards sandy bottoms. These differences signify administration tips (age.grams. minimal catch size) should not be an equivalent both for ocean cucumbers morphotypes.

  1. Introduction

  Although water cucumber fishing isn’t a vintage passion inside Colombia, for almost 20 years it’s become a supplementary way to obtain money to possess local organizations and you will fishermen on Colombian Caribbean coastline, whom pull so it resource with around zero control [1–4]. Angling knowledge of surrounding places, for example Panama, Mexico and Ecuador have indicated brand new susceptability from ocean cucumbers so you can over-exploitation due to low employment pricing, late maturity and you will density-dependent reproduction [5–7]. Yet not, inside the Colombia which pastime is still carried out illegally to your some other types and you can may be mostly unregulated and you can unquantified , encouraged because of the growing request off Western segments, in which ocean cucumber is a beneficial gastronomic joy of large economic really worth [8–10].

  Current facts on this subject fishery also confiscations produced by Colombian environment bodies indicate that one of several kinds normally caught as well as top matter for its defense and maintenance was Isostichopus badionotus [1, step 3, 11], since it is one of the most worthwhile regarding Caribbean interacting with prices during the Far eastern places between 132 and 358 USD Kilogram -1 . Unfortuitously, anglers just who offer sea cucumbers to help you intermediaries discovered typically only 3 USD Kg -step 1 [step one, 3].
