Introduction

Prior to their commercial exploitation, the rorquals (Mysticeti

Balaenopteridae) were one of the dominant, top trophic level components of

the pelagic ecosystem throughout the Southern Ocean. The six species of

this family are characterized by a suite of unique anatomical

characteristics that adapt them for filter-feeding on dense swarms of

eoipelagic macroplankton.lc crustaceans by a method referred to as "gulping"

or "engulfment" (Nemoto, 1959), Five of the six species have a

cosmopolitan distribution and are symoatric throughout much of the Southern

Ocean during the summer. These five species are the blue whale

(Balaenoptera musculus), the fin whale (B. physalus), the sei whale

(B. borealis), the minke whale (B. acutorostrRta), and the humphack whale

(Megaptera novaeangliae) (Mackintosh, 1965; Brown and Lock-yer, 1984).

From 1925/26 to 1984/85, the pelagic fishery for baleen whales in

the Southern Ocean (south of 40°S latitude) killed over one million whales

of these five species. In less than 50 years, the populations of four of

these species (all except the minke whale) were reduced by 90% or more

(Tonnessen and Johnsen, 1982: Mizroch, 1984). The catch records thus

provide an unparalleled set of data for evaluating the original

distribution patterns, movements, and relative abundance of these species.

These data were gathered by the Committee for Whaling Statistics in

Sandefjord, Norway, a function recently assumed by the International

Whaling Commission in Cambridge, England. A copy of these data is kept on

computer tape at the National Marine Mammal Laboratory in Seattle.

Although the current abundance and population trends of depleted

stocks are somewhat uncertain (e.g., Breiwick and Braham, 1984), management

efforts have been directed at encouraging a recovery of these orotected

species. As organizations such as the International Whaling Commission

(IWC) and the Commission for the Conservation of Antarctic Marine Living

Resources (CCAMLR) consider management and conservation strategies, they

will require information on interactions among whale stocks, their prey,

and commercial fisheries, In particular, data on the soatial and temporal

distribution of these components will be desirable.

- 116 -

To date , there have been no summaries of the whale catch data in a

convenient, readily available format. Therefore we have produced a

preliminary atlas that depicts the seasonal and geographical distribution

of the pelagic catches of each of these five species.

One purpose of the atlas is to facilitate management decisions

regarding the recovery of depleted whale stocks and possible competition

with commercial fisheries for their preferred prey. For example, these

data may help identify feeding areas that may be of importance to various

whale species. The atlas may also provide a stimulus for further analysis

of distribution and food habits data potentially available from whaling

catch records.

Methods

A series of computer-generated maps of the Southern Ocean was

produced. The pelagic catch data are displayed on a grid of 1° latitude by

2° longitude (111.1 x 170.4 kilometers at 40°s, 111.1 x 111.l kilometers at

60°S, and 111.l x 38.9 kilometers at so 0 s) with catch density gradients

represented by four distinct shading patterns. The shadings were designed

to represent the relative abundance of catch records within each map; hence

the numerical divisions between shading patterns differed depending on the

overall number of whales caught, and the absolute densities are not

comparable between maps. The class interval was calculated as a 4-step

geometric progression (base 2) with an open-ended upper interval, and the

upper limit of the first interval was set at the median (Evans, 1977). The

legend on each map indicates the calculated intervals, but since the upper

interval was open-ended, the actual maximum was indicated parenthetically.

The catch data shown on the maps are the pelagic data collected by

the Bureau of International Whaling Statistics (BIWS) from 1931/32-1979/80 .

Catches north of 40°S and from land stations were not included. Latitudes

and longitudes represent the noon position of the processing ship. The

computerized BIWS data were provided by the computing facility of the IWC.

- 117 -

Subsets of the B~WS files were selected to help elucidate spatial

and temporal relationships of catch records. Two groups of subfiles were

analyzed :

1) general distribution of catches by month (all years pooled),

and

2) inter-annual changes in the distribution of catches (using fin

whales as an example).

The first group of maps focuses on the distribution patterns within

scaGons. The Gecond group of maps was produced to help assess the extent

to which areas of high whale catches changed between seasons. This topic

seems particularly important in light of the recent results of surveys for

Antarctic krill (Euphausia superba), a pre ferred prey of several whale

species. Those surveys suggest a marked inter-annual variation in the

observed abundance of krill at selected study sites.

The maps were produced using a mapping computer package called

"WORLD Projection and Mapping Program, Version 3.51" (Philip M. Voxland ,

University of Minnesota, Minneapolis) on a Burroughs 7800 mainframe

computer at the Northwest and Alaska Fisheries Center, Seattle. The

coastline and i ce shelf data came from the "World Data Bank II" files (U.S.

Central Intelligence Agency, Washington, D,C,).

Results

A total of 57 maps were produced

l) A set of 24 maps (Figs 1-24) depicting the catches, all years

combined, for each of the five species in each of the five

summer months from December through April (December through

March for minke whales as there were no catches in April),

- 118 -

2) A set of 33 maps (Figs 25-57) depicting the catches of fin

whales for each season from 1952/53 through 1961/62, in each

month from January through March, plus catches for all ten

seasons combined for each of the three months.

Discussion

Valid interpretations of the information on these maps can be made

only if they are evaluated in the broad context of the life history and

ecology of each species, and of the history of whaling operations

throughout the Southern Hemisphere. There are striking differences in

overall latitudinal distribution of the different whale species; these

maps depict this gross difference clearly. As whalers shifted their

attention from one species to another, the geographic focus of operations

changed and hence the distribution of catches. In order to interpret these

data properly, it is important to differentiate between distribution

patterns influenced by natural factors, such as prey distribution, and

operational factors, such as a shift in target species.

In the second phase of this project we plan to undertake the

following:

1) A summary of the biology of each species especially their food

habits, migration, and the annual cycles. Included will be a

review of published mark-recapture data.

2) A review of the history of whaling throughout the Southern

Hemisphere. This will include complete tabulations of catches

(other than the pelagic data which form the basis of the maps)

of the following three fisheries (a) the 19th century

open-boat fishery (relevant only for humpback whales); (b) 20th

century winter catches north of 40°S; and (c) 20th century

shore station catches during the summer south of 40°S. Also

included will be a description of technological and legal

changes that affected the operations of the whale fishery .

example

- 119 -

3) Description of the data base for pelagic whaling in the

Southern Oce,an, an explanation of the computerized mapping

procedure, and the rationale for the cartographic conventions

that we have used.

4) A detailed statistical analysis for each species (including

summary maps, graphs, and tables) of changes in latitudinal and

longitudinal distribution and abundance both generally and by

sex and reproductive class. This should illuminate migration

and segregation patterns.

5) A detailed comparison (including summary maps, graphs, and

tc1blPs) of tPmporai anrl spa t ic1l di ff erence,; be twePn spe("ip,;.

Several additional topics have been suggested by this work, for

1) Analysis of food habits data by area and date. A qualitative

comparison of prey items recorded in harvested whales may

provide insight into seasonal changes in prey and distribution.

2) Comparison of whale and krill catches . Plotting the temporal

and spatial relationships between these groups may assist in

identifying potential conflicts between recovering whale stocks

and their prey.

3) Fine scale comparison of minke whale catch and sea ice

distribution. Satellite records of sea ice distribution are

available from years during which minke whaling was active. A

comparison of these data sets may elucidate the influence of

ice on the distribution of this species.

We hope that this atlas will help illuminate the ecological

relationships of these species not only to each other, but also to

physical, chemical, and biological features of the entire Southern Ocean

ecosystem. Moreover, we hope that it will stimulate further questions that

could be answered by detailed analysis of this large data base.
