This report presents findings from the spring of 2018, focusing on zooplankton biovolumes, ichthyoplankton composition, distribution, and frequency, particularly emphasizing Engraulis ringens and euphausiids eggs and larvae. The study spanned a vast area from Punta Mero (Tumbes) to Morro Sama (Tacna), covering a distance of up to 115 nm. Zooplankton biovolumes ranged widely from 0.005 to 6.76 mL/ m³, with a median of 0.26 mL/m³. Predominant biovolumes, falling within the range of 0.001 to 0.25 mL/m³ (48.0%), were primarily located within the continental shelf. This vast region stretched from Punta Sal to Punta La Negra and from the south of Pimentel to Morro Sama, reaching a maximum distance of 110 nm off the coasts of Paita, Malabrigo, and Pisco. Regarding ichthyoplankton (eggs and larvae), the families Engraulidae and Myctophidae stood out, accounting for 85 % and 50 % of the observed frequencies, respectively. Additionally,
the family Phosichthyidae exhibited a frequency of 45 %. Euphausiids in the calyptopis and furcilia stages were prevalent, with frequencies of 72 % and 75 %, respectively. Among the euphausiids, 4 genera and 14 species were identified, with Euphausia mucronata being the most common species, observed in both adult (34 %) and juvenile (26 %) stages.
