We conducted monthly visits to the coastal community of Mata de Limón (December 2011 to November 2012) in central Pacific of Costa Rica for assessment the extraction of the burrowing shrimp called coloncho Callichirus seilacheri, a species intensely caught as bait for fishing along the Pacific coast of Central America. The outcomes indicate that fishery effort varied between 4 and 14 harvesters day-1 with a high percentage of them from the same community (70-100%). Daily catch varied between 76 and 1120 shrimps and its value was strongly correlated with catches realized for the local harvesters (R2= 0.88). The shrimps density and total abundance in Mata de Limón was estimated in 1.2 ± 0.88 ind m-2 and 49,607 ± 3,638 individuals, respectively. Ovigerous females were exclusively present between May and November, peak in September. According to our outcomes, population of C. seilacheri in Mata de Limón could be in risk of overfishing if the daily catches exceed 800 individuals. The main results of the present study allow recommend the implementation of a total fishing ban during the reproduction peak of C. seilacheri directed to protection and conservation of this local resource for its sustainable harvesting. Also, we suggest the establishment of a management program between the community of Mata de Limón and the Instituto Costarricense de Pesca y Acuicultura (INCOPESCA) in order to optimize and legalize the extraction of this important resource.

The Family

The Panamic biogeographic province has long been thought to harbour a rich pyramidellid fauna. In the compilation of Keen (1971) the family is second only to the Turridae in being the most speciose gastropod family in the region, and no less than 350 species are listed. However a number of these have later been recognized to be synonyms, and in the update of the compilation by Skoglund (2002) the number of pyramidellids was reduced to 258.

A New Species

A redescription of Pagurus albus (Benedict, 1892) is presented together with a description of a new species of hermit crab, Pagurus pseudoalbus sp. n., from the Pacific coast of Costa Rica. Pagurus pseudoalbus sp. n. differs from P. albus and P. perlatus by the length of antennal acicles, which do not exceed the distal margin of the 4th antennal segment, whereas in the latter two species, the antennal acicles exceed the 4th antennal segment; the antennular peduncle is proportionally longer than the ocular peduncle in the new species compared to P. perlatus, but shorter than in P. albus; the palm of the right cheliped in P. pseudoalbus sp. n. is 1.3 times as long as broad, while in P. albus and P. perlatus it is 1.0 and 1.4 times as long as broad, respectively. Including the new species, the genus Pagurus in the Eastern Tropical Pacific currently includes 16 species.

AbstractDespite there is a growing interest in studying the presence and effects of microplastics (MP) in fishes and other aquatic species, knowledge is still limited in tropical areas. In this study, we examined the presence of MP in the gastrointestinal content of 30 filter feeders of thread herring, Opisthonema complex (Clupeiformes: Clupeidae) from the Central Pacific coast of Costa Rica. We detected the presence of MP in 100% of the individuals with an average of 36.7 pieces per fish, of which 79.5% were fibers and 20.5% particles. To our knowledge, this is the first study in Costa Rica that demonstrates the presence of MP in planktivorous fishes. The effects of microplastics ingestion by O. libertate and its transit through aquatic food webs should be studied in greater detail, with greater number of sampling points at different times of the year. However, our work confirms that contamination by microplastics is having direct effects on the marine life of Costa Rica.CapsuleThis is the first multidisciplinary study in Costa Rica demonstrating the presence and nature of microplastics in the digestive tract of planktivorous fish.

The neotropical viperid snake genus Lachesis Daudin, 1803 accomodates four venomous species that occur in forested areas from Central America, in Nicaragua and Costa Rica, to most of South America, southwards into southeastern Brazil and Bolivia (Campbell & Lamar 2004). This genus is unique among neotropical crotalines in having a high number of ventrals, dorsal, and cephalic scales, while also being oviparous (Campbell & Lamar 2004). Lachesis melanocephala Solórzano & Cerdas, 1986 is a large-sized viper, distributed from the Pacific coast of southwestern Costa Rica to northwestern Panama (Campbell & Lamar 2004). This species reaches up to 2.4 meters of total length, and can be diagnosed based on its uniformly black dorsal head pattern and inconspicuous postocular black stripe (Fig. 1; Campbell & Lamar 2004).
