Rastrelliger brachysoma is a mariculture candidate species, but reproduction in captive fish has been problematic. This report examines the difference in the HPG axis, the neuroendocrine system and the development of reproductive tissues between captive vs. wild male R. brachysoma. The gonadosomatic index (GSI) of sexually mature male wild R. brachysoma was 1.12±0.34 and 1.94±0.26 during the non-breeding and breeding seasons, respectively. Captive R. brachysoma had a GSI of 1.88±0.17. All wild R. brachysoma were in the late spermatogenic stage irrespective of seasons. Immunostaining results showed that sbGnRH-immunoreactive neurons were distributed in three areas of the brain, namely the nucleus periventricularis, nucleus preopticus and nucleus lateralis tuberis. Follicle stimulating hormone and luteinizing hormone immunoreactivities were also observed in the pituitary gland. The levels of brain sbGnRH and GtH mRNA were not significantly different between the non-breeding and breeding seasons, but captive fish displayed (times or percent difference) lower mRNA levels than wild fish. These results suggest that these hormones control the testicular development in R. brachysoma and that the impaired reproduction in captivity may be due to their relative lower expression levels of follicle stimulating hormone and luteinizing hormone genes.

Though a large number of techniques are available for the study of aquatic bacteria, the aim of this study was to establish a technique for analysing free-living and biofilm prokaryotic cells through laboratory assays. In particular, we wished to analyse the efficiency of ultrasound to detach and disrupt biofilm, to obtain an efficient stain treatment for quantifying free-living and biofilm prokaryotes in flow cytometry (FC), and to compare epifluorescence microscopy (EFM), scanning electron microscopy (SEM) and FC for quantifying free-living and biofilm prokaryotes#. Marine-grade plywood substrates were immersed in natural marine water that was conditioned for 12 days. At 6 and 12 days, water aliquots and substrates were removed to estimate free-living and biofilm prokaryote density. Ultrasound efficiently removed marine biofilm from substrates (up to 94%) without cell damage. FC analysis (unstained) reliably quantified marine plankton and young or mature biofilm prokaryotes compared with other staining (acridine orange, 4′,6-diamidino-2-phenylindole, propidium iodide and green fluorescent nucleic acid), EFM or SEM techniques. FC and SEM achieved similar results, while a high variability was observed in the EFM technique. FC was faster and more precise than SEM because the count is not dependent on the observer.

We determined the efficacy of marking the otoliths of three small-sized progenetic gobies to validate their increment periodicity. These small gobies have high mortalities and rearing difficulties, making direct validation difficult. The otoliths were marked by immersing the fish in a bath of alizarin red S. The fishes were euthanatized and the number of increments in their otoliths laid down after the fluorescent mark were counted and compared with the number of elapsed days. The results validated the daily periodicity of Aphia minuta and Pseudaphya ferreri. The high mortality hindered the validation of Crystallogobius linearis.

The present study was conceptualized to study the muraenid species (moray eels) occurring around the volcanic archipelagos of the Azores, Madeira, Selvagens, Canary and Cabo Verde islands (eastern-central Atlantic). The biogeographic patterns of these species were analysed and compared. We then hypothesized that this fish family is an ideal group for testing at small-scale the coherency of Macaronesia and its direct biogeographic units: i.e. the Azores, Webbnesia and Cabo Verde, as proposed in recent scientific literature. Additionally, this paper provides for the first time separate fishery statistics for this group in the region that were analysed to contrast the biogeographic results.

There is growing demand for the territorial tube-building genus Marphysa (Eunicidae: Polychaete), commonly known in Portugal as “goose”, for use as fishing bait, and it is being harvested all around the world for that purpose. Effects of intraspecific density on juvenile growth were studied over a four-month period in laboratory facilities. Three polychaete densities (low, 50 worms; medium, 150 worms; and high, 250 worms) were used in a 0.25 m aquarium containing sandy sediment and recirculating water. Total length, dry weight and number of segments were recorded for 60% of the initial population. All polychaetes were also counted to determine mortality rate and territorial behaviour through the existence of body lesions and broken and regenerating posterior segments. The results obtained in this study showed that density had a significant effect (p<0.001) on growth rates in any of the densities studied and that growth was significantly higher at lower densities (p<0.001). For all density levels, estimated daily growth was higher in the first month, decreasing progressively over time. The high aggressiveness and territorial behaviour of Marphysa “sp.” juveniles, well evidenced by the highest mortality (35%) under high density and by the presence of worms with lesions under low density (30%) observed in the first month, suggests that territoriality is probably the main factor involved in the organization and spatial arrangements of individuals within a population. Marphysa juveniles probably compete for burrow space. The results reveal that Marphysa juveniles have a very territorial and aggressive behaviour that should be considered if the species is used for aquaculture production. Additional studies are required to determine the density effects for different developmental stages.

The age and growth patterns of the mesopelagic fish Ceratoscopelus maderensis (family Myctophidae) of the western Mediterranean Sea were described throughout its entire life cycle (from larvae to adult stages) using the sagittae otoliths of 59 individuals collected in December 2009. Three characteristic zones were identified along the cross-section of the sagittae (larval, metamorphic and juvenile-adult zones). Assuming growth rings as daily increments, the age of the analysed individuals (from 3.5 to 64 mm standard length [SL]) would range from 7 to 332 days. The relationship between the number of increments and the fish SL was fitted to a von Bertalanffy growth model (SL=70.5899A~(1–exp(–0.0501(t+2.6705))). The growth pattern of C. maderensis in the western Mediterranean Sea was similar to that reported for this species in the northeast Atlantic Ocean. Though from a body size of 40-45 mm SL, growth rates declined more slowly in individuals from the western Mediterranean Sea, growth differences between these individuals and those from the northeast Atlantic Ocean were not statistically significant. This study provides new insights into the age and growth patterns of one of the most abundant mesopelagic fish species in the Mediterranean Sea that have clear implications for the study and management of marine ecosystems.
