RESUMEN. El camarón de río del sur Samastacus spinifrons, es una de las seis especies de la Familia Parastacidae (Crustacea, Decapoda, Astacidea) que habita las aguas dulces de Chile desde el río Aconcagua hasta la península de Taitao, y actualmente, la única que es considerada atractiva para la acuicultura nacional. En este artículo se revisa su potencial para la acuicultura con fines comerciales o de repoblamiento. Para ello se analizan: a) las ventajas y desventajas biológicas de esta especie ante eventuales actividades de cultivo en confinamiento; b) las experiencias de cultivo que a la fecha se han efectuado en Chile haciendo énfasis en sus respectivos aportes; y, c) las probables causas que han impedido que su cultivo se consolide en el país. Finalmente, de acuerdo a los análisis antes señalados se plantea una propuesta de cultivo que se considera la más adecuada para S. spinifrons. Palabras clave: Samastacus spinifrons, camarón de río, experiencias de cultivo, potencial para la acuicultura, Chile. Culturing freshwater crayfish Samastacus spinifrons: a new alternative for diversifying Chilean aquaculture?ABSTRACT. The freshwater crayfish Samastacus spinifrons, is one of six species of the Family Parastacidae (Crustacea, Decapoda, Astacidea) inhabiting freshwaters in Chile from the Aconcagua River to the Taitao Peninsula, and the only one that is currently considered attractive for national aquaculture. In this article, we review the potential of this species for aquaculture with commercial or restocking purposes. For this, we analyze: a) the species' biological advantages and disadvantages in an eventual situation of confined culture; b) previous culturing experiences carried out in Chile, with an emphasis on their respective contributions; and c) the causes that were likely to have prevented the consolidation of culturing this species in Chile. Finally, the above analyses provided the basis for our proposal of the most appropriate way to culture S. spinifrons.

“…the larval and juvenile phase of H. gammarus. Here we use 18 • C, similar temperatures to Arnold et al (2009), which are optimal for hatching and growth (Wickins and Lee, 2002;Kristiansen et al, 2004) and 10 • C which are less optimal conditions (Schmalenbach and Buchholz, 2013). The temperatures chosen are not a likely climate change scenario but a physiological test.…”

“…Temperature was run at 10 and 18 • C, to simulate a lower limit and an optimum threshold for homarid lobsters, respectively (Wickins and Lee, 2002;Schmalenbach and Buchhoz, 2013). Initially a middle temperature of 14 • C was also included, but due to the limited number of larvae available this had to be excluded.…”

Deformities in larvae and juvenile European lobster (<i>Homarus gammarus</i>) exposed to lower pH at two different temperatures

Abstract. The ongoing warming and acidification of the world's oceans are expected to influence the marine ecosystems, including benthic marine resources. Ocean acidification may especially have an impact on calcifying organisms, and the European lobster (Homarus gammarus) is among those species at risk. A project was initiated in 2011 aiming to investigate long-term effects of ocean acidification on the early life-cycle of lobster under two temperatures. Larvae were exposed to pCO 2 levels of ambient water (water intake at 90 m depth), medium 750 (pH = 7.79) and high 1200 µatm pCO 2 (pH = 7.62) at temperatures 10 and 18 • C. The water parameters in ambient water did not stay stable and were very low towards the end of the experiment in the larval phase at 10 • C,with pH between 7.83 and 7.90. At 18 • , pH in ambient treatment was even lower, between 7.76 and 7.83, i.e. close to medium pCO 2 treatment. Long-term exposure lasted 5 months. At 18 • C the development from stage 1 to 4 lasted 14 to 16 days, as predicted under optimal water conditions. Growth was very slow at 10 • C and resulted in three larvae reaching stage 4 in high pCO 2 treatment only.There were no clear effects of pCO 2 treatment, on either carapace length or dry weight. However, deformities were observed in both larvae and juveniles. The proportion of larvae with deformities increased with increasing pCO 2 exposure, independent of temperature. In the medium treatment about 23 % were deformed, and in the high treatment about 43 % were deformed. None of the larvae exposed to water of pH > 7.9 developed deformities. Curled carapace was the most common deformity found in larvae raised in medium pCO 2 treatment, irrespective of temperature, but damages in the tail fan occurred in addition to a bent rostrum. Curled carapace was the only deformity found in high pCO 2 treatment at both temperatures. Occurrence of deformities after five months of exposure was 33 and 44 % in juveniles raised in ambient and low pCO 2 levels, respectively, and 21 % in juveniles exposed to high pCO 2 . Deformed claws were most often found in ambient and medium treatment (56 %), followed by stiff/twisted walking legs (39 %) and puffy carapace (39 %). In comparison, at high pCO 2 levels 71 % of the deformed juveniles had developed a puffy carapace. Overall, about half of the deformed juveniles from the ambient and medium pCO 2 treatment displayed two or three different abnormalities; 70 % had multiple deformities in the high pCO 2 treatment. Some of the deformities in the juveniles may affect respiration (carapace), the ability to find food, or sexual partners (walking legs, claw and antenna), and ability to swim (tail-fan damages).

“…Therefore, some of these animals have been increasingly subject to farming to supplement those caught by fishing (Wickins & Lee, 2002). One recent candidate for aquaculture development has been the European shore crab, Carcinus maenas, which is valued as bait for sport angling and eaten in continental Europe.…”

A novel bacterial disease of the European shore crab, Carcinus maenas – molecular pathology and epidemiology

A novel bacterial disease of the European shore crab, Carcinus maenas -molecular pathology and epidemiology Several rickettsia-like diseases have been reported in arthropods (insects and crustaceans), some of which result in significant losses of economically important species such as shrimp and crabs. This study reports on the molecular pathology of a recently emerged disease of the European shore crab, Carcinus maenas, termed milky disease -named as a result of the unusual milky appearance of the haemolymph (blood). This disease was more prevalent (.26 %) during summer months when the water temperature in a pilot crab farm was approximately 19 6C. The putative causative agent of the disease was a Gram-negative bacterium that could not be cultured on a range of agar-based growth media. Diseased crabs showed significant reductions in free blood cell numbers and total serum protein. Such animals also displayed raised levels of glucose and ammonium in blood. Ultrastructural and in situ hybridization studies revealed that the causative agent associated with milky disease multiplied in the fixed phagocytes of the hepatopancreas (digestive gland), ultimately to be released into the haemolymph, where the circulating blood cells showed little response to the presence of these agents. Attempts to induce the infection by short-term temperature stress failed, as did transmission experiments where healthy crabs were fed infected tissues from milky disease affected individuals. Sequence analysis of the 16S rRNA gene from the milky disease bacteria indicated that they are a previously undescribed species of a-proteobacteria with little phylogenetic similarity to members of the order Rickettsiales. INTRODUCTIONThere is increasing interest in the likely effect of global climate change on diseases in both wild and cultured organisms (Harvell et al., 1999(Harvell et al., , 2002Lafferty et al., 2004). In particular, aquatic animals are highly sensitive to temperature change and it is widely accepted that elevated temperatures can lead to reduced oxygen tension in the water, higher microbial growth and immunosuppression, resulting in higher prevalence of disease (Le Moullac & Haffner, 2000). For example, brown trout in alpine rivers and streams have been found to show increasing prevalence of proliferative kidney disease caused by the myxozoan parasite Tetracapsuloides bryosalmonae over the last 20 years (Hari et al., 2006). These increased temperatures drive the proliferation of T. bryosalmonae in its intermediate bryozoan host (Tops et al., 2006). Equally at very low water temperatures, some aquatic animals may become immunocompromised as a result of a failure of the immune system to mount an effective immune response to bacterial challenge (Chisholm & Smith, 1994).One potentially important result of climate change will be alterations in the effectiveness of aquaculture as a method of supplementing fish and shellfish for human and animal consumption taken from the wild (Alborali, 2006). Currently, it is thought that at least 15 ...
