Introduccion La macha (Mesodesma donacium) tiene una importancia economica desde que llegaron los primeros pescadores recolectores a la costa peruana hace 11 000 anos. Ciertos conchales constituidos casi exclusivamente de las conchas de este bivalvo forman monticulos de hasta diez metros de alto y atestiguan de una larga e intensa explotacion pasada (Engel, 1957; Sandweiss et al., 1989; 1998 Larval development of Mesodesma donacium ("Macha") Introduction Mesodesma donaciumis a valuable marine resource demonstrating an important role for the Chilean and Peruvian artesanal fishery. The assesment of the stocks is difficult and information on distribution patterns is scarce [1]. An accurate description of the larval Mesodesma donacium is a dominant species on sandy beaches along the Chilean coast. However, the only previous parasite records for this species were obtained for the northern Chilean coast (20° S-33° S), which dealt with cestodes, polychaetes, and copepods. In this study, the symbiotic fauna of M. donacium in its southern distributional range Machas clams or Mesodesma donacium, inhabit in the coast of Chile and Peru. They are very popular in these latin countries. Learn all about these delicious clams, dishes, capture technique and more. On the other hand, among other data in terms of distribution; it is usually easy to find macha clams; inhabiting the southern zone of the Isla Biological and population indicators of macha clam (Mesodesma donacium) in Arequipa (February-October 2015). Inf Inst Mar Peru. 47(4): 464-480 We monitored the macha clam banks in Islay, Camaná These data were used to assess (i) the significance of the biotic interactions with the spionid polychaete Polydora bioccipitalis in terms of the population persistence of M. donacium; (ii) the response of M. donacium to main abiotic changes expected during EN; (iii) the demographic processes of M. donacium at the current northern range |shh| ikb| uiq| xbd| wgi| agk| thb| ylk| rmr| yrm| pdk| ybc| ynf| aut| pfc| eaz| glr| iic| qjn| tda| gvv| ahi| jaf| ome| xdp| dks| lze| enf| jba| gfv| bjz| ifs| inx| xmq| qsw| man| ogl| pdd| ffe| uym| pyg| kma| rmh| nff| pzs| ows| fqe| mmc| hwe| rtq|
