As seawater temperatures rise in the ocean due to global temperature change, altered mean precipitation, and weather patterns, native species face uncertain futures. The alteration thermal tolerance was assessed wild‐captured tropical sea urchins ( Lytechinus variegatus ) from Caribbean Sea then maintained under controlled conditions. Three experiments were performed: (1) favorable growth temperature: after maintaining wild at three different (22, 24 26°C) for 70 days, it observed that 22°C...

Abstract Aquaculture offers solutions to meet the growing global demand for fish, and reports from UN‐FAO indicate that aquaculture production in Latin America (LA) has grown at rates above world average recent years. One of major constraints diversification LA is control reproduction several popular native fish species which difficulties captive propagation have not yet been sufficiently overcome. This article reviews use hormone treatments promote females these species. played a key role...
The knowledge of the chemical composition invertebrates as sea cucumber contributes to improving our understanding these living organisms. This study compared wild Isostichopus sp., between February 2013 and January 2014. Sea cucumbers were captured by hand artisanal fishermen transported alive laboratory Aquaculture Universidad del Magdalena (Colombia), where they subsequently killed taken freeze until analysis. For proximate analysis 20 g muscle used for each sample. (in triplicate) was...
Pitheciids are known for their frugivorous diets, but there has been no broad‐scale comparison of fruit genera used by these primates that range across five geographic regions in South America. We compiled 31 lists from data collected 18 species (three Cacajao , six Callicebus Chiropotes and four Pithecia ) at 26 study sites countries. Together, contained 455 plant 96 families. predicted 1) closely related would demonstrate the greatest similarity lists; 2) pitheciids living closer proximity...
The effects of food deprivation and environmental salinity (<1, 10 20) on survival, fish morphology, organization the digestive system body lipid reserves in European eel Anguilla anguilla during transition from glass to elver, were evaluated. Fasted elvers kept fresh water able withstand starvation for >60 days, while those brackish environments (salinity reached level irreversible at 37 35 respectively. high contained liver inclusions abdominal cavity (perivisceral deposits) might...
<p>Los pepinos de mar tienen un importante papel ecológico en el medio marino, ya que son capaces alimentarse la materia orgánica e inorgánica, con lo cual contribuyen a oxigenación y transferencia energía ecosistema. En general, existe una falta conocimiento morfología básica especies nativas pepino función los órganos vitales. El objetivo este estudio fue describir histología del tracto digestivo (DT) tres holotúridos bahía Rodadero, Colombia. Treinta ejemplares...
Isostichopus sp. is a variety of badionotus, proposed as new species, which has been intensely fished in the Colombian Caribbean, arousing interest for its aquaculture. This study evaluated effect two culture densities (1–3 larvae ml−1), temperatures (23°C and 26°C) microalgae diets (Isochrysis galbana, Chaetoceros calcitrans, Nannochloropsis oculata 1:1:1 I. C. calcitrans 1:1) on survival, development growth larvae. Larval lasted 22 days until metamorphosis to doliolaria larvae, 7 later,...
The aim of the study was to determine effect two photoperiod regimes under artificial conditions on growth performance and survival in European eel Anguilla anguilla during transition from glass elver. fish were held 12-h-light:12-h-dark (12L:12D) continuous darkness (DD) fed fast trials lasting 80 days. Fed kept dark showed higher somatic growth, a better feed conversion ratio, protein lipid content, with significant differences between treatments. Dark environment increased rate comparison...
Isostichopus badionotus and sp. are two holothuroids exploited in the Caribbean region of Colombia. Until recently, they were considered a single species. During one year, 222 individuals 114 I . collected bays Santa Marta to study their reproductive biology collect information on size, weight habitat. Both sea cucumber morphotypes showed an annual cycle, with season from September November, closely related increase water temperature rainfall. In both cucumbers population structure exhibited...
The most relevant changes in Acipenser baeri eye organization were detected between hatching and 5 days post hatch. At this age, the had an anterior chamber, lens, iris, choroid gland, scleral cartilage, cornea a vitreous chamber lined by retina (with two photoreceptors: rods single cones).
Surface morphological structure of the body, and radial organs in sea cucumbers Isostichopus sp. aff badionotus, badionotus morphotype I I. II were characterized by histological techniques. The three morphotypes studied demonstrated differences between them gross morphology distribution body fleshy projections dorsal region. wall consists a layer epidermal cells covered thin cuticle, superficial dermis formed compact with large cytoplasmic contents, slack or delimited connective tissue into...
